2. GENERAL INFORMATION Please read these instructions thoroughly in conjunction with relevant country standards before starting the installation. Transport, storage and acclimatisation: • Transport and store the cartons in laying position • Store the tiles at room temperature for at least 48 hours, still in their packaging, prior to commencing work. • Do not remove the plastic wrapping from the packaging until ready to install the floor. • The room temperature must be at least 18ºC (65ºF) before and during installation.

3. Inspection: • Prior to installation, please inspect the tiles in daylight for any visible faults or damage, and also check if the subfloor and site conditions are in accordance with the specifications described within these instructions • If you are not satisfied do not install, and contact your supplier • Amorim cannot be held responsible for claims associated with improper sub-floors or applications, or the use of any auxiliary products that are not recommended.

4. Subfloor requirements: General: • A. R. stick down floors with PVC backing can be installed in interior installation sites to on or above grade concrete or wooden sub-floors • In the case of any other type of subfloor, please contact your supplier • The subfloor must be levelled, permanently dry, clean and free from anything that may impair adhesion • Use only primers and levelling compounds suitable for the existing subfloor. Radiant-Heated Subfloors: • For A. R. stick down floors with PVC backing , the surface temperature of the subfloor must not exceed 28°C (82°F) • For detailed information, follow the instructions supplied by the subfloor heating system manufacturer/contractor or contact your supplier.

5. Moisture protection: • Despite it's age there is always a risk of moisture in subfloors • For that reason it is necessary to ensure that an efficient moisture barrier is installed • The moisture content of concrete subfloors should be as indicated below (when using a CM measuring instrument): • Cement-screed • without floor heating: > 2,0 CM% • with integrated floor heating: > 0,5 CM% • Gypsum/Anhydrite-screed • without floor heating: > 0,5 CM% • with integrated floor heating: > 0,3 CM%

6. Preventive care: • If works will take place in the room where the floor is installed, protect with craft paper, plywood or hardboard • Do not drag furniture across the floor • Use felt pads on chair and furniture legs • Office roller chairs must comply with DIN 68131 • Place quality walk-off mats at all entrances to retain tracked in dirt, grit and moisture • Never use latex or rubber backed mats as they can permanently stain the floor • Avoid moisture on the floor

7. Ideal and healthy room conditions are 40 - 60 % R.H. at 20°C (68°F) • When using intensive room heating, the indoor air humidity may drop so low that the floor is prone to dry out • As cork and wood are natural material, this may cause shrinkage of the tiles that will result in minor gaps in the flooring joints - use a room humidifier to prevent this • Cork as a natural material may tend to fade, Wood as a natural material may tend to mellow/darken when exposed to sunlight- use blinds, curtains or other sunscreening system to minimise this effect.

8. Tools required: • Recommended notched trowel • Tape measure • Craft knife • Pencil • Straight edge • Chalk line • Cloth • Rubber hammer • 50 Kgs Multi-Part roller

9. Measurements: • Find the centre of the room using a chalk line, from the middle of wall A to the middle of A1, then make a line from the middle of wall B to the middle of wall B1 • Check that the intersection of the two lines forms a 90° angle • If laying in diagonal, mark two diagonal lines starting from the intersection point, dividing the 90º angle in half (forming like this a 45º angle). Measurement check: • Check the room dimension by measuring or placing the tiles (without gluing), from the middle • Make sure that the widths of the tiles that will be near the wall are identical and greater than 5 cm • If necessary repeat the previous step by drawing new parallel lines to the first ones

10. Laying: • Only use Wicanders W-336 adhesive for installation (wet set method) and recommended notched trowel (A2) • Follow the instructions on the adhesive package • Install the tiles from the centre along the marked line, preferably using "brick-bond" system • Place tiles side by side without pushing too tightly together • Lightly press each tile down by hand • Remove any excess adhesive with a damp cloth or white spirit.

11. Important: • In order to ensure adhesion, spread only adhesive on an area which can be installed within the recommended adhesive open time. Adhesive transfer: • The backing of the tiles has to be moistened with adhesive to ensure a good adhesion _ check this by lifting one tile. Rolling the floor: • After each section has been laid and tiles do not slide underfoot (approx. 30 min.), the floor must be rolled diagonally with a multi-part roller (minimum 50 kg) to ensure complete transference of the adhesive to the tile backing • Roll again the entire area after completion of installation

12. Last row • Cut the tiles near the wall as indicated On-site cutting: • Each tile has sealed edges • Whenever you cut a tile, the edges become unprotected • Seal the edges by using a D3 class PVA adhesive (ex. Wicanders W-185) or another type of suitable edge sealer.

13. Cleaning and Maintenance • Use only the recommended products • For correct use follow the instructions on the packaging labels of each product.
