Polymer Floor & Wall Coatings: Selection, Preparation, Installation and Troubleshooting


System selection criteria l.jpg
System Selection Criteria

When designing a floor and/or wall system, selection of products will depend upon working environment and severity of use.

  • Physical: Light foot traffic or heavy mechanized traffic? Industrial process or laboratory/clean room?

  • Chemical: Cleaning agents, process chemicals, combinations.

  • Temperature: Freezers, steam washdown, extreme ambient temps.

  • Electro-static: High-voltage equipment, static-generating machinery

  • Value Engineering: Floor design for the immediate environment Multiple issues occurring over one area

Systems

When designing a floor and/or wall system, selection of products will depend upon working environment and severity of use.

  • Coatings

  • Slurries

  • Mortars

  • Urethane Cement

  • Wall systems


Slide4 l.jpg

Coatings

  • Advantages:

  • Inexpensive

  • Aesthetics

  • Cleanability

  • Concrete protection

  • Chemical resistance*

  • Disadvantages:

  • Resistance to physical abuse

  • Repair of poor substrate conditions

  • Less product for the same amount of surface preparation

  • Life-cycle costing



Slide6 l.jpg

What is a Slurry?

Resinous coatings filled with aggregate (approximately 2 parts aggregate to 1 part resin) which is applied at 1/16” to 3/8” in thickness.

  • Disadvantages:

  • Moderate to good resistance to physical abuse

  • Will not resurface poor concrete

  • Thermal shock resistance

  • Downtime

  • Advantages:

  • Great value/installed cost

  • Significant improvement to abuse compared to coatings

  • Non-skid applications

  • Resin-rich systems



Slide8 l.jpg

What is a Mortar?

Resinous coatings filled with aggregate (approximately 4 or 5 parts aggregate to 1 part resin), which is applied by trowel and finished. The systems range in thickness from 3/16” to 3/8”.

  • Disadvantages:

  • Cost

  • Skill level required for installation

  • Resin-aggregate ratios

  • Downtime

  • Advantages:

  • Resistance to physical abuse

  • Resurface poor concrete

  • Thermal shock resistance

  • Life-cycle costing



Slide10 l.jpg

What is a Urethane Cement?

Urethane emulsion combined with cement and silica sand (approximately 3 parts aggregate to 1 part resin), which is raked and finished at ¼” to 3/8” thickness.

  • Disadvantages:

  • Aesthetics

  • Cost

  • Limited colors

  • Skill level required for installation

  • Advantages:

  • Great resistance to physical abuse

  • Bond in wet environments

  • Thermal shock resistance

  • Fast installations

  • Chemical resistance



Slide12 l.jpg

Wall Systems

High-build coating systems

Fiberglass reinforced epoxy systems

Flexible epoxy wall systems

  • Disadvantages:

  • Cost

  • Substrate imperfections

  • Downtime

  • Advantages:

  • Chemical resistance

  • Wash-down resistance

  • Impact resistance

  • Gloss retention

  • Cleanability

  • Aesthetics



Concrete requirements mix design l.jpg
Concrete Requirements: Mix Design

Proper concrete mix design can produce a slab that is ideally suited for bonding to a polymer topping.

  • Standard mix design:

  • Topical treatment: Seamless, film-building sealers, form release

  • Fiber reinforcement: Coatings, self leveling floors 3/16”

  • High early mix design:

  • Concrete additives: Plasticizers, Gill 33


Slide15 l.jpg

Successful Concrete

  • “At-use” environment

  • Surface preparation

  • Moisture testing

  • Control conditions of installation

  • Dew point vs. surface temperature during installation

  • Sub grade

  • Vapor barrier

  • Water to cement ratio

  • Aggregate selection and gradation

  • Finishing

  • Curing


Slide16 l.jpg

Concrete Concerns

  • Moisture vapor transmission

  • Levelness of installation

  • Drain height

  • Lightweight concrete

  • Fly ash pozzolans


Moisture related issues l.jpg
Moisture-related issues

Improper treatment of moisture-related issues can result in blisters, delamination and potentially a complete floor system failure.

Moisture Measurement: A simple calcium chloride test will determine the presence and force of any moisture migrating through the slab. Acceptable levels vary with each system and manufacturer.Causes:Fast-track construction schedules Mix design (wet pour) Topical treatments (slow hydration) Pouring slab in a pan Ground or soil conditions Humidity inside vs. outside Chemistry changes in flooring products


Treatments for moisture problems l.jpg
Treatments for Moisture Problems

There are several techniques/products available for the prevention and remediation of moisture-related problems.

  • Slab design: vapor barrier, mix design

  • Time: may not be on your side

  • Temperature and humidity control

  • Topical vapor barriers (Aqua Armor, Koester, FloorSeal)

  • Product or System: water-based products, thin “breathable” coatings and urethane cements


Scheduling planning for work l.jpg
Scheduling & Planning for Work

A timely and efficient mobilization requires room preparation and proper communication between Project Management, Flooring Contractor, and all other trades.

Heat: Temperature must be at least 55*F for coatings and toppings. 65*F to 75*F is ideal for most systems. Room/slab temperature directly affects coverage rates of product.

Light: The presence of finished lighting impacts application schedules, cure time and aesthetics of finished floor.

Power supply: 220v 3-phase, 60 Amp. or 480v 3-phase, 30 Amp. Installation equipment pulls total of amperage when starting up, and will blow breakers.

Scheduling & Planning for Work

Effect on facility operations and return to service.

Other Trades: Damage to floors, walk off job site, power, lighting

Effect on existing operations: Product odor, contamination of inventory, work areas adjacent to application, fire, safety


Slab preparation l.jpg
Slab Preparation

Chemical process: Effective in the removal of adhesives, oils, animal fats. Acid etching, stripping, detergents.Mechanical process: Shot blasting, grinding, scarifying, scabbling.

Water process: Water jet blasting is entirely dust free. Consider its effect on product selection and time of application.

Dust Control: All slab prep machinery is connected to vacuum with HEPA filtration.


Wrap up l.jpg
Wrap-up

Return to service: Maximum allowable shut-down time can dictate the type of system and product selected. Quick-cure polymers, such as MMA and urethane concrete systems can greatly reduce application time and return facilities to service in a matter of hours.Application rates: Installation rates will vary with required prep work, system selected, product manufacturer and schedule. Per-foot rates can range from $2.00/ft. up to $12.00/ft. or more.
