Ⅰ.PREPARATION
1.Subfloor Requirements
1) Hardness: No hollowing. No sand accumulation and sand loose.
2) Flatness: Flatness should be measured with a 2-3 meter spirit level and a feeler gauge. It will be up to standard if the gap is below 2mm.
3) Cleanliness: Subfloors should be free of debris, paint, dust.
Note: Rough subfloors shall be constructed with extra strength self-leveling cement after they get cleaned up.
2. Pre-laying
Allow the roll to sit in the area to be installed for a minimum of 24 hours prior to install.
Ⅱ. INSTALLATION
1.Adhesive Type
It’s recommended to use the two-component polyurethane adhesive. (Need to confirm the performance of the adhesive.)
2. Adhesive Mixing
Mix the adhesive evenly in strict accordance with proportions as per the manufacturer’s instructions.
3. Adhesive Spreading
1) Laying the adhesive in accord with rubber roll.
2) Areas with adhesive spread must be 5CM bigger than the areas to be covered by the rubber roll. And full glue down is mandatory.
3) After the adhesive is spread, lay the rubber roll into the wet adhesive when viscosity works as per its properties.
4. Laying
1) The first roll must be straight,otherwise it will affect the paving of the remaining rolls.
2) The side joints between the rolls must be glued and squeezed tightly together in a single direction.
3) Press the side joints to make them flat and tight.
4) Roll the floor with a 30-50 KG roller.Roll 5-8 times within every 30 minutes.
5) Keep the rolls surface clean. Do not allow the adhesive to tarnish the rolls surface. It’s mandatory to verify the type of adhesive before the application. (When the performance of the adhesive can not be identified, sample taken for adhesive bond tests should be conducted.)
Ⅲ.CLEANING & MAINTENANCE
1. Mop or wet vacuum floor daily. Regular cleaning is required for those high traffic areas.
2. Use neutral cleaning agents. Pick up solution with a wet vacuum.
3. Take care NOT to damage the floor with any sharp object. No cutting, no stabbing, no needling.
4. Take care NOT to pour any colored pigment or solvent on the floor.
5. Take care NOT to pour any oil, heat up,or light the fire on the floor.
6. It’s recommended to do the regular maintenance using transparent liquid wax to keep the surface bright.
