VOC

Volatile Organic Compounds

Volatile Organic Compounds are inherent in the automotive refinishing trade. Everyday bodyshops across the country are releasing VOC’s into the atmosphere during the course of automotive refinishing chiefly through the evaporation of solvents. VOC,s are primarily found in the solvents used to thin or reduce automotive refinish products however, a small amount is also released from Primers, Sealers, Colorcoats, Clearcoats and the Activators associated with them. Once the VOC’s are released they combine with automobile emissions, dust and natural sunlight producing atmospheric pollutants referred to as photochemical smog. The release of VOC’s in industry continues to contribute to the ongoing problem of air pollution and as a result have led to increasingly stringent regulations governing the emissions of VOC’s into the atmosphere at both the federal and state level.

VOC Regulations and the BodyshopVOC regulations were first adopted in the State of California in the 1980’s. These regulations were originally developed to minimize VOC emissions and subsequently minimize the level of air pollution in the Los Angeles Basin. Since they were implemented they have had a dramatic impact on the air quality in Los Angeles. Bodyshop emissions regulations are now enforced by the Environmental Protection Agency and as a result a two-part plan was established in order to control the emissions of VOC’s. This two part plan functions at both the federal and state levels. The National Rule was adopted by the federal government for the entire country and consists of mandated limits set for the allowable VOC emissions for each specific product category. On the State Level the National Rule still applies however, each state is required to adopt it’s own clean air program. A states clean air program may be equal to the National Rule in areas less polluted and more stringent in areas determined to be heavily polluted. A state may not enact a clean air program more lenient than the National Rule established by the EPA. In either case state regulations will take precedence over the National Rule if they are more stringent.

Since 1998 the paint manufacturers have been required to produce VOC compliant products for use in the automotive refinish industry. Prior stocks of non-compliant products were allowed to be sold until their existing inventories were depleted to prevent from incurring a considerable amount of waste paint in the supply chain. As a result a multitude of newly developed VOC compliant products has been introduced to the refinish industry. In addition new technologies in spray guns have also improved the overall transfer efficiency of automotive refinish products. The spray guns available today boast a transfer efficiency of 65% plus while the paint guns of yesterday would typically lose 85% of their overall content to the atmosphere in the form of overspray. These two developments alone have significantly lowered the VOC emissions once considered acceptable in the industry.

slide6

Current VOC RegulationsThe current “National Rule” establishes the following allowable limits for “as applied” VOC’s for the following product types:

These “National Rule” limits have been established by the EPA for allowable VOC emissions across the United States of America.

    • National VOC Regulations
    • PRODUCT TYPE VOC/lbs./gal.
      • Pretreatment / Wash Primer 6.5
  • Primer Surfacer 4.8
  • Primer Sealer 4.6
  • Single Stage & Basecoat** 5.0
  • Tricoat & Quad-coats 5.2
  • Specialty Coating 7.0
  • ** The Single Stage & Basecoat category include the Clearcoat as a part of the allowable VOC Limit
slide7

California VOC Regulations

The State of California has been the model for the rest of the country in enacting clean air laws and they continue to further develop their clean air program setting attainable goals for the continuing reduction of pollutants released in the refinishing process. Let’s examine California’s Clean air program to identify how, where and why additional regulations are enacted at the state level. The map below identifies the Air Quality Management Districts developed by the State of California and the corresponding chart on the next page identifies the rule governing the district in addition to the allowable clearcoat VOC for each area.

Air Quality Management Districts in California

Air Quality Management Districts in California

slide8

Each county in the State of California is a part of an Air Quality District either by itself or joined by other counties to form an Air Quality District. These districts each have a specific rule developed to contribute to minimizing the VOC’s released through automotive refinishing. As you can see parts of California are subject to the “National Rule” while others are not. Each area is analyzed by its geography, population, pollution level and VOC emitting facilities to determine an acceptable level of emissions for that specific geographic area.

slide9

Additional Regulatory Requirements

  • The development of regulations governing paint products have also produced additional requirements designed to coincide with regulatory requirements such as
  • Inspections to insure repair facilities are complying with established VOC regulations
  • Record keeping and reporting of sprayed VOC’s by the bodyshops
  • Use of High Volume Low Pressure paint application equipment
  • Bodyshop registrations
  • In many cases failure to adhere to these requirements will incur a monetary penalty designed to financially penalize the business for failing to comply with regulations designed to improve air quality and minimize pollution.
  • Calculating VOC
  • VOC.s are measured in pounds of VOC per gallon in its “ready to spray (RTS)” form, meaning that all the necessary components have been mixed together to make the product “ready to spray”. Matrix System publishes VOC information on Technical Data (TDS), Material Safety Data Sheets (MSDS) and on the AccuShade™ Formula Retrieval Program to help with VOC reporting requirements. In addition, to make it easy all VOC’s are reported in RTS fashion to eliminate the guesswork.
  • To Calculate Sprayed VOC’s:
  • We will use 1Qt of basecoat and 2 Qt of clear for our example:
  • MPB Basecoat = 6.6 lbs./gal. (RTS)
  • MS-42 Clearcoat = 4.2 lbs./gal. (RTS)
  • Divide the amount of paint mixed by the reported pound of VOC per Gallon
  • Divide the amount of clearcoat mixed by the reported pound of VOC per gallon
  • Combine the results for a sprayable VOC for the products

Example

2Qt / 6.6 = 3.3

1Qt / 4.2 = 1.05

Total Sprayed VOC’s = 4.35

slide10

Matrix System has offered National Rule and additional VOC compliant products since January of 2000. Many of these products meet the National Rule and others have been developed especially for areas requiring more stringent VOC levels such as the State of California. These products have continued to undergo development in order to provide body shops with the highest performing, productive and profitable VOC compliant products available to meet a wide range of bodyshop situations.

slide14

Equipment Selection

Equipment selection is a very integral part of automotive refinishing. Just as a mechanic uses specialized, or specific tools to accomplish a variety of repairs the same is true for the painter. Materials used at the various levels of refinish require differing equipment in order for them to be properly applied. In addition, a single refinish material such as MP-600 may spray better or worse depending on a specific manufacturers spray gun and the way in which it is set up. Paint and equipment manufacturers typically offer performance settings charts recommending certain, air caps, fluid nozzles, air pressure, and fluid pressure settings to be used as starting points to produce the best atomization and gun performance (see figure 1). Using the incorrect tool for a specific task can oftentimes be the difference between delivering a flawless finish and creating additional refinish work.

Figure 1

Sharp Manufacturing Recommendations

slide15

ApplicationThe application of automotive paint can be challenging for a novice and relatively simple for a seasoned professional. Learning the skills required to successfully paint an automobile takes time and practice. Every manufacturer product sprays slightly differently and to further complicate this every paint gun is also unique. For example, with all things being equal (mix ratio, hardener selection, reducer if added) MS-42 high solids clearcoat will spray differently through a Sata paint gun than it will in a Devilbiss model. It is these variables that require practice in order to correctly apply automotive refinish products.

Anatomy of a Paint Gun

Selecting the proper paint gun setup is simply a matter of using the correct tool for the specific task at hand. Just as a mechanic uses specialized tools to complete a repair so will a painter. There are two distinct paint gun setups common throughout the multitude of paint gun manufacturers. These gun setups typically offer a setup for topcoat applications (Topcoat setups typically offer a fluid nozzle, needle and air cap set up for 1.2-1.4 mm sizes) and a slightly different setup for undercoat applications (undercoat setups typically offer a fluid nozzle, needle and air cap set up for 1.6-2.0 mm sizes). This is chiefly due to the different nature of the products being applied.

slide16

Proper Paint Gun Techniques

Using The proper spray gun technique is very important. These simple techniques involve the following:

Spray Gun Angle

Distance from Surface

Gun Travel Speed

Spray gun angle is essential to the application of an evenly distributed paint film being applied across the surface being painted. A recommended angle of 90° to the surface is the optimal angle at which to operate a paint gun. When the paint is applied at this angle an even film is applied to the surface. When the gun is held at angles other than 90° and uneven film is generally the outcome.

Distance from Surface is also an essential element to correctly apply automotive paint. Generally, the recommended distance from the surface to operate the paint gun is 8-10 inches. This allows the paint to evenly atomize as it is applied to the surface of the vehicle. Holding the gun too far away will cause the atomized paint to widely separate and likewise holding the gun to close will restrict the atomization size of the particles.

Gun Travel Speed Should be enough to allow for a 40-60% overlap of the paint products and provide an even film build without overly wetting the surface as to cause runs.

The following pages contain reference information for the application and mixing of Matrix System products.

slide17

slide29

Solvent Selection

Using the correct solvent for the application temperature plays a key role in the application of automotive paints. Solvent is the vehicle by which the paint is transported from the paint gun to the surface of the vehicle. In addition, solvent evaporates from the newly applied finish at a rate dictated by the ambient air temperature and the solvent speed itself. The rate at which the solvent evaporates is critical to eliminating problems in the application process.

Cooler temperatures cause paint products to flash and dry at a rate slower than normal, therefore faster solvents are used in cooler temperatures to help speed the evaporation rate. Using too slow a solvent in cool temperatures may cause the following conditions:

  • Sags
  • Runs
  • Solvent Pop
  • Wrinkling
  • Blistering
  • Cracking
  • Loss of gloss**

**For every 15° decrease in temperature the dry time will double

Conversely, hotter temperatures cause paint products to flash and dry at a faster rate than normal, therefore slower solvents are used in hotter temperatures to help slow the evaporation rate. Using too fast a solvent in hot temperatures may cause the following conditions

  • Loss of adhesion
  • Dry Spray
  • Mottling
  • Clouding
  • Orange Peel
  • Pinholing

** For every 15° increase in temperature the dry time will be cut in half

slide33

Blending

Blending is a method by which basecoat; single stage color or clearcoat is sprayed so that the edge of the color or clearcoat “melts” into the surrounding area. Blends are used mostly in spot and panel repair to trick the eye and conceal the repair. Blending a color creates an illusion that minimizes a color, texture, or metallic flop mismatch. Always be prepared to blend! It should be standard procedure to blend all repairs. Blending is the most effective color-matching tool in the painter’s arsenal. A good blend should be smooth, gradual and virtually invisible to the eye. There should be no telltale ring or pronounced shaded perimeter around the repair.

Techniques for blending are available for both color and clearcoat applications and are relatively simple to master with a little practice. Additionally, there are many different methods of panel preparation. The following method is recommended for blending basecoat color:

Matrix System Color Blending Procedure

Wash area thoroughly with soap and water to remove contaminates that solvent based cleaners cannot remove effectively.

Clean repair are with MX-9000 Wax and Grease Remover or MXW-9001 where VOC regulations require use.

Sand repair area with 400-600grit sandpaper or equivalent.

Sand beyond the repair area with 1200-1500 wet/dry ultra fine sandpaper or scuff beyond the repair area with a scotchbrite while utilizing 3/M 6014 Prep and Blend to prepare the adjacent panels for color blending and clearcoat application.

Reclean repair area with MX-8000 pre-paint cleaner or MXW-9001 where VOC regulations require use. Wipe off any MXW-9001 residue with a clean damp cloth.

Clean the surface with a tack cloth to remove contaminates prior to paint application.

slide34

Color Blending Cont’d

Apply 2-3 coats of Matrix System basecoat or until hiding is achieved directly to the repair area gradually extending each coat 4-6” past the previous coat. Allow a 10-minute flash time between coats, and 15-30 minutes for the final coat to dry prior to applying clearcoat.

*** Note MPB-500 may be used as an initial basecoat providing metallics, micas and pearlescents with a proper base for optimal orientation of these products***

Once hiding has been achieved the color must be blended into the existing OEM finish on the adjacent panels to smooth the color transition. Fan the color outwards from the repair area by applying color at a 90° angle to the surface at the beginning of the stroke and graduating the angle of the fan on the outer edge of the repaired area until the fan is parallel to the paint surface.

Continue blending the color until an undetectable blend has been achieved.

Allow the basecoat a 15-30 minute flash time before applying a clearcoat.

Apply clearcoat to the overall repair and blend area. Follow the manufacturers specific instructions for correct clearcoat application instructions.

Color Blending Tips:

Prepare adjacent panels for blending at the start of the repair rather than in the middle

Consider the following appearance issues when blending color

Color (Hue, Value, Chroma)

Texture (Amount of Orange Peel)

Gloss (Distinctness of Image)

Metallic Distribution (On the Face, Flash and Flop)

slide35

Matrix System Clearcoat Blending Procedure

Wash area thoroughly with soap and water to remove contaminates that solvent based cleaners cannot remove effectively.

Clean repair area with MX-9000 Wax and Grease Remover or MXW-9001 where VOC regulations require use.

Sand repair area with 400-600grit sandpaper or equivalent.

Sand beyond the repair area with 1200-1500 wet/dry ultra fine sandpaper or scuff beyond the repair area with a scotchbrite while utilizing 3/M 6014 Prep and Blend to prepare the adjacent panels for color blending and clearcoat application.

Reclean repair area with MX-8000 pre-paint cleaner or MXW-9001 where VOC regulations require use. Wipe off any MXW-9001 residue with a clean damp cloth.

Clean the surface with a tack cloth to remove contaminates prior to paint application.

Apply 2-3 coats of Matrix System basecoat or until hiding is achieved directly to the repair area gradually extending each coat 4-6” past the previous coat. Allow a 10-minute flash time between coats, and 15-30 minutes for the final coat to dry prior to applying clearcoat.

*** Note MPB-500 may be used as an initial basecoat providing metallics, micas and pearlescents with a proper base for optimal orientation of these products***

Once hiding has been achieved the color must be blended into the existing OEM finish on the adjacent panels to smooth the color transition. Fan the color outwards from the repair area by applying color at a 90° angle to the surface at the beginning of the stroke and graduating the angle of the fan on the outer edge of the repaired area until the fan is parallel to the paint surface.

slide36

Clearcoat Blending Procedure Cont’d

  • Continue blending the color until an undetectable blend has been achieved.
  • Allow the basecoat a 15-30 minute flash time before applying a clearcoat.
  • Apply adequate amount of clearcoat to the overall repair and color blend area stopping just short of the designated clearcoat blending area.
  • Blend the clearcoat by dusting the clearcoat edge with a mixture of your clearcoat and a slow reducer mixed as follows:
  • Clearcoat 1 Part
    • Slow Reducer 2 Part
  • Apply an additional coat of reduced clearcoat to the same area extending 1”-3” past the previous coating.
  • When the clearcoat has cured properly, polish the clearcoat edge with a fine or non-aggressive polish to eliminate the visible clearcoat edge.
  • Clearcoat Blending Tips:
  • Blend clearcoat only when you cannot clear an entire panel or no clear break point exists.
  • Warranty repairs for O.E.M. specify to extend the application of clearcoats to the nearest panel edge whenever lacking a clear break line or edge on which to stop.
  • Choose the smallest area available when blending clearcoat.
  • Use a slow reducer when blending clearcoat to provide additional time for the reducer to bite into the old finish.
  • When blending clearcoat it may be helpful to lower your air pressure and narrow your fan pattern to optimize the blend.
slide37

Sanding

Sanding surfaces for paint is perhaps the most important part of the repair process as cars are prepared for paint. Sanding is carried on throughout the entire repair process from fixing vehicle damage to wet sanding the final coat of clear. Sandpaper performs the function of smoothing the surface for the next layer or coat to be applied. A repair may begin with 36 grit sandpaper used for grinding the sheet metal and eventually graduate to 2000 grit sandpaper when the final buff of the clearcoat takes place. For every layer of the repair process that builds a surface up to be sanded smooth there is an appropriate sandpaper required to properly complete the current task and take the repair to the next level.

The following recommendations for sanding are based on each specific coating applied to finished body filler work throughout the repair and preparation process as the vehicle damage is gradually sanded to the point of topcoat application.

slide38

Matrix System Sanding/Preparation Procedure

  • Remove any wipers, emblems, bodyside moldings, pinstriping from the area(s) to be refinished. Place these items in a plastic bag for storage to prevent loss.
    • This operation will save time and materials when masking and make it easier to de-wax and prepare the repaired area(s) for paint application in addition to producing better overall quality in the final results.
  • Wash the repaired area(s) thoroughly with soap and water to remove contaminates solvent based cleaners cannot remove effectively.
    • Washing a car prior to starting body or paint work is done to remove contaminates such as dust, dirt, insects etc. A clean car provides the technician a good look at the condition of the paint to identify any additional dents, dings, chips, scratches or otherwise that may have been missed when initially inspecting an automobile for repairs. Washing the car will not remove contaminates such as sap, road tar, road paint, asphalt, grease etc. These contaminates can be removed by means of a chemical wax and grease remover, Goof Off® or other types of products designed specifically for the removal of these common contaminates.
  • Clean the repaired area(s) with Matrix MX-9000 Strong Wax and Grease Remover or MXW-9001 where VOC regulations require use.
    • Removing additional contaminates acquired from daily driving such as sap, road tar, road oils, asphalt, wax, silicones, grease and etc. is accomplished by using Wax and Grease removers specifically formulated for the chemical cleaning of these contaminates and others. Removal of these contaminates is essential to insure a flawless finish, failure to remove grease or additional contaminates can cause a myriad of problems once the application of paint begins.
slide39

Final sand all body filler and feather-edge adjacent areas to the body filler with 180 grit or equivalent sandpaper.

  • Finish sand the body filler and feather-edge the old finish ½” minimum for each coat of substrate with 180 grit or finer sandpaper to remove all the rough sanding operation scratches, once completed clean with compressed air and solvent clean with MX-9000.
  • Sand beyond the repair area with 1200-1500 wet/dry ultra fine sandpaper or scuff beyond the repair area with a scotchbrite while utilizing 3/M 6014 Prep and Blend to prepare the adjacent panels for color blending and clearcoat application.
    • It is much easier to prepare adjacent panels for blending prior to the paint operation in order to minimize the likelihood of going back and preparing additional panels for blending in the middle of the paint operation.
  • Apply 1 medium coat of Self Etching Wash Primer to the area(s) consisting of body filler, bare metal and the adjacent feathered edge of the old finish. Allow a 30 minute flashtime prior to applying the subsequent primer surfacer.
    • Applying an etching primer over the body filler, bare metal and feather-edge provides corrosion protection and adhesion for the following undercoats.
    • Matrix System MP-600 is recommended
  • Apply 2-3 coats of two-component primer/surfacer to the area(s) covered by Self Etch Primer. Use 40-50 PSI at the gun or 5-10 PSI at the air cap when using HVLP. Allow a 10-15 minute flash time between each subsequent coat.
    • Primer/Surfacers serve the function of filling imperfections and build a surface up to be sanded level and smooth.
    • Matrix System 2KPB is recommended.
slide40

Apply alight coat of contrasting color over the primer surfacer prior to sanding to use as a “Guide Coat”

    • Guide coats identify high, low areas and imperfections in the primer/surfacer as it is sanded level and smooth. The contrasting color makes these areas easily visible in the sanding process.
  • Machine sand the primer/surfacer level and smooth with 320 grit or equivalent sandpaper to remove the 180 grit scratches used to final sand the body filler.
    • Sand at a low flat angle to minimize undulations.
    • Turn down the sander speed to maintain control in sensitive areas.
    • Don’t apply excessive pressure when using a DA, let the machine do the work for you.
  • Apply an additional 2-3 coats of two-component primer/surfacer to the area(s) sanded. Use 40-50 PSI at the gun or 5-10 PSI at the air cap when using HVLP. Allow a 10-15 minute flash time between each subsequent coat.
    • Priming the repair area(s) again will build the surface up to be final sanded before applying a topcoat
  • Final sand by machine or hand with 600 grit or equivalent sandpaper to remove the 320 grit sand scratches. The primer/surfacer should be level and smooth when completed and ready for paint.
    • Sand longitudinally with the car to minimize sand scratch visibility
    • When cross cutting with sandpaper change directions by 30°, 45° and 90° angles to provide the best leveling action, however the last few strokes should be longitudinal to minimize sand scratch visibility.
  • Use a sanding block when sanding by hand to minimize undulations caused by uneven finger pressure when sanding
slide41

Masking

  • Masking is most often thought of as a means to prevent overspray from reaching nearby surfaces. However, it also serves a purpose of protection from accidental damage created by sanding or otherwise preparing surfaces for paint. It is wise to mask off areas of the car not being repaired even if you are not using power tools for repairs. An accidental swipe with sandpaper can leave permanent marks on chrome, moldings, emblems etc.
  • Matrix System Masking Procedure
  • Blow out the automobile interior, door jambs, underhood, decklid, wheels and wheel wells with compressed air.
  • Steel wool all exterior glass and chrome trim around the automobile.
    • This will ensure all the glass and chrome on the automobile is clean and free of overspray from body repair. In addition, the masking tape will adhere better and be less likely to blow off during the paint process.
  • Wash the entire automobile exterior with soap and water.
    • Rinse off the entire car prior to washing to remove any loose dirt that may scratch the finish when washing.
    • Begin washing the top of the car and work towards the bottom to keep the dirt rinsing downwards.
    • Rinse the washcloth frequently to keep excess dirt from accumulating on the rag and possibly scratching additional body panels.
    • Blow the residual water off the automobile using compressed air.
  • .
slide42

Allow the automobile to completely dry prior to masking.

    • Masking tape will not stick to wet surfaces and will likely blow off if applied to a wet surface.
  • Keep the masking machine with you and begin at the front of the automobile and work your way around the automobile panel by panel.
  • To eliminate overspray all masking must be done as tightly as possible. Loose tape or excessive paper may cause the tape to blow off during the painting process.
    • A right-handed person should hold the tape roll in their right hand and guide the tape with the left hand (the opposite applies for left-handed people).
  • Masking specific parts can require different methods of application and specific paper sizes. The following is a guide to use when masking certain parts of the automobile.
    • Windows
    • Select the appropriate paper size
    • Windshields – 36”
    • All other windows – 18”
    • The length of the paper selected should be 6” longer than the window being masked
    • Place the tape edge along the top of the window and center it
    • Fold the excess up the sides and secure
    • Tape down any creases
    • Grilles
  • Start at the bottom and work your way up
    • Wheel wells and Rocker Panels
    • Use 6” paper
    • Tuck paper underneath
    • Secure the ends
    • Mirrors
    • Outline base
    • Cover with 6” paper
slide43

Bumpers

Use a sheet of paper long enough and wide enough to cover the bumper

Tuck excess paper underneathSecure the ends

Antenna

Outline base

Cover tube with 3” paper

Body Side Moldings

Mask with ¾ “ tape

Mask larger body side moldings with appropriate size paper

Emblems, Letters

Mask with 1/4 “ Tape

Two-Tones Stripes/ Stickers

Use fine line brand tape sizes appropriate for the job

Jambs

Use 6” paper around the jamb

Secure any loose paper

Tips for Masking:

After applying a piece of tape, go back and tightly press it to the surface to prevent paint from getting underneath the tape.

If the tape will not stick to a surface utilize a wax and grease remover to clean the surface, this may also be used sparingly on rubber moldings.

Whenever applying a two-tone follow the manufacturers recommendations regarding masking freshly painted surfaces.

Do not remove tape from a wet paint job. Follow the manufacturers recommended dry times and remove the tape after the new paint has dried.

When possible cut the tape as opposed to tearing it as this can cause the tape to lift and stretch.

Never peel up when removing masking tape, instead peel back away from the car and over the tape itself.

Never allow tape to remain on a car for more than a few days, in direct sunlight or when it gets wet, as this will cause the tape to become extremely difficult to remove requiring hours of painstaking labor.

Mixing Automotive Paint

  • The following information is designed to aid in the identification and mixing of automotive paint according to a specific manufacturers color code information for both domestic and import automobiles.
  • A paint formula is a distinct order of operations that must be completed in order to properly mix the correct color. There are two distinct methods for mixing automotive paint. The first method relies on mixing the paint by adding a specified amount of grams for each of the toner colors required to mix the formula, the second is an accumulating method for completing the same task.
  • Matrix System Color Identification and Mixing Procedures
  • Locate the Vehicles Color Information
  • Color code locations vary from manufacturer to manufacturer, however most manufacturers remain consistent to their individual color code placements on automobiles. Matrix System has provided the attached charts for domestic and import color code locations by manufacturers.
  • Identify the Correct AccuShade™ Formula
          • Enter the manufacturers color code in the OEM Paint Code: search field
          • Enter the paint type you prefer in the Paint Type: search field
          • Enter the vehicle manufacturer in the Manufacturer: search field
          • Enter the manufacturer model year in the Model Year: search field
          • Select the Search Icon or press Enter to begin the formula search you have specified
slide45

Once the formula has been identified double check the following formula information

          • Manufacturer is correct
          • Vehicle production year is correct
          • Color name (If known) is correct
          • AccuShade™ Formula Retrieval Tips:
          • When searching for formulas, providing more information refines searches, while providing less information will broaden search results
          • Common or known formulas can be entered directly into the Formula No: search field to quickly access commonly used formulas
          • AccuShade™ color chips have the formula number for the specific color chip you are viewing printed on the reverse side of the color chip for easy formula access in the AccuShade™ Color Retrieval Disk
          • Always pay special attention to the notes field of every formula as some may contain special instructions for the specified formulation
  • Double Check the Corresponding AccuShade Color Chip to The Vehicle
        • Once the automobile color code has been identified, and the corresponding formula has been accessed pay special attention to the area on the formula screen that identifies the corresponding color chip information.
        • Compare the color chip to the vehicle to insure a color match can be obtained
        • If the color chip is a close match to the vehicle determine if a variance of the standard will be required to more closely match the vehicles color
        • IF THE COLOR CHIP DOES NOT MATCH THE CAR, DOUBLE CHECK THE COLOR CODE AND FORMULA INFORMATION BEFORE MIXING ANY PAINT!
slide46

Individual Gram Measurements

Cumulative Gram Measurements

  • Mix the Paint
    • A paint formula is a distinct order of operations that must be completed in order to properly mix the correct color. There are two distinct methods for mixing automotive paint. The first method relies on mixing the paint by adding a specified amount of grams for each of the toner colors required to mix the formula, the second is an accumulating method for completing the same task.
    • Individual gram mixes require the scale to be reset to zero at the start of the mix and in between the addition of each and every toner until the formula is mixed
    • Cumulative mixes require the scale to be reset to zero when at the start of the mix and subsequently adding each toner listed to the weight required by the formula in an accumulating fashion until the entire formula is mixed
  • ** Do not reset the scale to zero at any point in this operation!
slide47

Paint Mixing Tips:

      • Thoroughly agitate the intermix system toners for 15 minutes 3 times daily. Do not attempt to mix paint without properly agitating intermix toners, failure to do so can result in mismatched color mixes.
      • Slowly open the pour spout as you begin to add toner to your mix. It is very easy to accidentally over pour when adding toner.
      • Check your inventory to make sure you have enough toners to complete the mix once you begin.
  • Wrong Color? Double Check the Following
      • The color code from the vehicle is correct?
      • Does the car have a secondary color code?
      • Is the color part of a scheme?
      • The formula is correct to the color code, year and make of the vehicle?
      • The color chip (if available) matches the vehicle to the paint formula?
      • Does the color code or vehicle identification number suggest a variant of the standard formula is
      • the correct color code?
      • Are the toners regularly agitated?
      • Was the mix order followed?
      • Were the correct toner amounts added to the mix?
      • Are you viewing the color under the correct light source?
  • Common Reasons for Mismatched Color:
      • Painter chose the wrong variance for the vehicle
      • Intermix toners were not properly agitated
      • Application technique of the painter
      • Shop conditions, cooler shops produce darker colors
      • Improperly measured intermix toners
      • Many other variables
slide48

Color Matching Rules to Live By:

Follow proper stock rotation policies, follow daily toner requirements and pay attention to notices the manufacturer mails you. There may be a recall notice included.

To do a good job of color matching, one must be able to see colors as they actually are. One of every twelve people is partially or totally colorblind. If you have normal color perception, learning to match colors is largely a matter of being careful, having patience, and remembering and observing what takes place when certain colors are added.

For color adjusting, use intermix toners that are uniform in tinting strength and stick with them.

Only tint using intermix toners from the same technology as the material you are tinting (or equivalent offset) I.e. do not use acrylic enamel toners to tint acrylic urethane basecoat.

When tinting bright metallic colors, transparent or weak intermix toners should be used to maintain the “brightness” or “vividness” of the color. Toners such as transparent red, transparent yellow, weak white and weak black should be used. Other toners may be used, they may however “washout” the color.

If uncertain which variance to mix, choose a lighter one. You can easily make a color darker, it is hard to make lighter.

Tint systematically. Keep track of which toner and how much has been added. If you know how far a certain amount of toner has moved the color, you have a better idea how much more is needed.

Don’t make the final judgment on the match while the material is wet. The color will change as it dries.

Check the color in daylight as well as artificial light. It may not look the same in both lights.

Determine which direction the mixed paint has to be adjusted. Make sure you use descriptions in three dimensions.

Review the formula used to mix the paint. When adjusting color, try to use intermix toners that are used in the original formula. You don’t want to confuse things!

If the mixed color is the wrong hue (red shade instead of green shade), select an intermix toner from the opposite side of the color wheel to “kill” the red shade. In this instance add green to kill the red hue.

ALWAYS SPRAY A TEST PANEL!

Automotive Painting

  • Automotive painting is a discipline requiring skill and patience in order to correctly apply paint without fail. Automotive painters must always be ready to utilize their experience and know how especially when confronted with a situation that may make or break a paint job. In order for a painter to produce consistent, repeatable results we must utilize procedures for both preparation and application of the automotive finish to minimize the likelihood of problems encountered throughout the refinishing process. The following steps provide the automotive painter with the best possible practices of preparation and application of automotive finishes, however they cannot provide the automotive refinisher with the experience and know how that are gained through the actual application of automotive finishes.
  • The following procedures assume the vehicle has been sanded, washed, masked, the color has been matched and is awaiting final preparations before entering the paint booth.
  • Matrix System Paint Preparation Procedures
  • Insure the Paint Booth is clean
    • Sweep the floor and walls to loosen any dirt, dust or debris from previous painting
    • operations
    • Blow out the paint booth with compressed air to remove the contaminates generated
    • by sweeping the floor and walls
    • Wet the floors and walls to trap any additional dirt, dust or debris not removed
  • Cleaning the paint booth is critical to obtaining a flawless finish. A properly cleaned spray booth will help to control contaminates such as dirt, dust and debris and minimize the possibility of these particles inadvertently ending up in your finish.
  • Inspect the vehicle area(s) to be refinished
    • Inspect the repair work
    • Has the body damage been repaired
    • Is the original contour of the body restored
    • Are there any visible gouges, scratches, chips, waves or etc. visible in the repaired area
    • Has it been final sanded with 600 grit or equivalent
    • Inspect the areas adjacent to the repairs
    • Was the remainder of the substrate material final sanded with 600 grit or equivalent for an overall refinish, or 1200-1500 grit or equivalent for spot work requiring blending color
slide50

Blow the entire vehicle off with compressed air outside of the paint booth

  • Wipe the entire refinishing area down MX-8000 pre-paint cleaner
    • Use clean lint free rags
    • Begin at the top of the car and work towards the bottom
  • A final wipe down with wax and grease remover is essential to promoting a flawless finish. The final wipe down will remove minor traces of wax, grease, oils, fingerprints, etc… from the vehicle and provides a surface that is free from contaminates, setting the stage for a problem free paint job.
  • Pull the vehicle into the paint booth
  • Seal all the doors of the paint booth and start the intake and exhaust fans
  • Inspect the masked areas of the vehicle
    • Check for any loose paper
    • Check for any loose tape
    • Secure all loose paper and tape
    • Tape all paper creases
    • Cover the wheels
  • Prepare all required materials for paint application
    • Double check your inventory to insure you will not run out of materials in the middle of the refinish job
    • Mix enough of the materials you will require to apply the paint to the car
slide51

Wipe the vehicle down one final time with a tack cloth

    • Completely unfold the tack cloth and form into a ball shape
    • Wipe the vehicle surface down lightly with the tack cloth to pick up any lint, dust, debris or other particles that have settled on the vehicle since entering the paint booth
    • Do not apply pressure when wiping the surface off
  • Stock the paint booth with extra supplies to minimize contamination by entering and exiting the booth
  • Every painter should prepare for the work ahead by stocking the booth with the items required to complete the paint job. Being improperly prepared to complete a paint job once started opens the door for opportunities to contaminate or cause further additional problems.
  • Stock your booth with:
  • 1. Extra tack cloths, extra tape, extra razor blades, extra paint strainers
  • 2. A sufficient amount of paint to complete the coat you are applying
  • 3. Any additional tools such as a step stool, box or scaffolding required
  • Matrix System Painting Procedure (Spot Repair)
  • Apply the first coat of paint directly to the repaired areas
    • Apply the paint in even strokes
    • Maintain a 90° angle to the surface which you are painting
    • Maintain a distance of 8”-10” from the surface you are painting
    • Overlap each successive stroke by 40-60%
    • Apply the coating 2”-4” past the edge of the repaired area
  • Allow a 15 minute flash time

    • Overlap each successive stroke by 40-60%
    • Apply the coating 2”-4” past the edge of the previously applied coating
  • Continue to apply color coats using the same method until hiding has been achieved
  • If blending is required to match the color to the car then refer to the instructions for blending color in the blending techniques section of the manual otherwise continue on with #8
  • Allow a 30 minute flash time prior to applying clearcoat
  • Lightly wipe down the surface of the automobile with a tack cloth to pick up any lint, dust or debris that may have settled on the surface.
  • Apply the first coat of clear to the entire surface area being refinished
  • Apply the clear in even strokes
    • Maintain a 90° angle to the surface which you are painting
    • Maintain a distance of 8”-10” from the surface you are painting
    • Overlap each successive stroke by 40-60%
  • Allow a 15 minute flash time
  • Apply the second coat of clear directly over the previously applied coat
  • Apply a third and final coat of clear if necessary
  • Once the repair work has been completed allow a 15 minute purge time prior to force drying the vehicle
slide53

Matrix System Painting Procedure (Overall)

  • Complete vehicle refinishing incorporates many of the same principles and practices as spot and panel refinishing from surface preparation to applying the clearcoat with one main exception. There is no need to blend color or clearcoat into adjacent panels. Instead we are repainting the car from the ground up and this requires smooth fluid motion as we make our way around the vehicle to maintain a wet on wet application minimizing overspray.
  • Apply the first coat of paint to the vehicle systematically

    • Maintain a distance of 8”-10” from the surface
  • Allow a 15 minute flash time
  • Apply the second coat of paint to the car in the same way the first coat was applied
  • Allow a 15 minute flash time
  • Continue to apply subsequent coats until hiding or acceptable coverage has been achieved using the same procedures
