Instructions
Surface Preparation
-
All surfaces must be between 40°F (4°C) and 104°F (40°C), structurally sound, clean, and free of dirt, oil, grease, loose paint, laitance, concrete sealers, or curing compounds.
-
Ensure the surface is plumb and level within ¼ inch (6mm) over 10 feet (3 meters).
-
Smooth rough or uneven concrete surfaces with a screed or plaster material to achieve a wood float finish (or better).
-
Dampen dry, dusty concrete slabs or masonry and remove excess water before installation. New concrete slabs must be damp cured and at least 28 days old before application.
-
Incorporate expansion joints through the tile work to match any construction or expansion joints in the substrate. Do not cover expansion joints with mortar.
-
Gresbond PUA-100 is recommended for tile or stone installations on plywood and wood substrates.
Mixing
-
Pour clean, potable water into a clean mixing bowl.
-
Add CX-2 powder to the water (approximately 5 - 5.5 liters of water per 20 kg of powder).
-
Mix by hand or with a slow-speed mixer until a smooth, trowelable consistency is achieved.
-
Allow the adhesive to slake for 5 minutes.
-
Adjust consistency if necessary.
-
Remix before applying with the proper sized notched trowel.
-
For large format tile or stone installations on exterior surfaces, contact Gresbond technical services.
Application
-
Apply adhesive to the substrate with the flat side of the trowel, pressing firmly to ensure good contact.
-
Use the proper sized notched trowel to ensure full bedding of the tile.
-
Comb additional adhesive onto the substrate with the notched side of the trowel. Use the appropriate trowel size to ensure full coverage of the tile back. Spread only as much adhesive as can be covered with tile within 10 minutes.
-
Back-butter large format tiles (greater than 12” x 12” or 300mm x 300mm) to provide full bedding and support.
-
Place tiles into the wet, sticky adhesive and tap them in using a beating block and rubber mallet to embed the tile and adjust the level.
-
Periodically remove a tile to check for complete adhesive coverage by inspecting the amount of adhesive transferred onto the back of the tile.
-
Use spacers to create grout joints between tiles/stones. The joint width should follow the architect’s or engineer’s recommendations. Remove spacers once the adhesive has set firmly.
-
If the adhesive skins over (loses tack), remove it and replace it with fresh adhesive.
-
Apply adhesive to the substrate with the flat side of the trowel.
-
Tiles must be fixed within 10-15 minutes of adhesive being applied, depending on the porosity of the surface and atmospheric conditions.
-
Leave no voids behind tiles.
-
Use suitable support along with adhesive for fixing tiles on vertical surfaces.
-
Leave adequate joints between individual wall and floor tiles using spacers. The joint width shall be as per the recommendation of architect / engineer.
-
Clean off surplus adhesive from the tile face and between joints.
-
Clean tools and tile work with water while adhesive is fresh.
Grouting
-
Begin grouting after a minimum curing time of 24 hours at 70°F (21°C). Use Gresbond's KE-100 series epoxy grout or unsanded grout mixed with KGA-100 Grout Admix.
-
For maximum stain resistance on interior spacer joints, use KE-100 Stain- resistant Grout.
PRECAUTIONS & NOTE
-
Always add powder to water.
-
Do not add excess water than recommended.
-
Never add sand & cement at site.
-
Do not use on wet screed. Surface must be fully cured.
-
Do not use the adhesive to correct surface irregularities greater than 12 mm.
-
Protect from direct rainfall/foot traffic for at least 24 hours.
-
Leave gap between the tile & fill gaps with Gresbond tile grout.
-
Designer/applicator must evaluate the use of an additional mechanical fastening system for extra security for more than 3m height (such as steel hooks fastened to the substrate).
Limitation
-
Do not apply directly to gypsum plaster or boards, fibre cement boards or other drywall partitions, plywood, chipboard, particleboard, decorative laminates or resilient flooring, metal, plastic, deformable surfaces or subject to vibrations. Use Gresbond PUA-100 as per application.
-
Adhesives for ceramic tile, bricks and stone are not designed as replacements for waterproof coating. Use waterproofing coating before tiling for wet area.
-
Do not use for fixing artificial/ nano/ engineered stone/ composites/ metal tile. Use Gresbond PUA-100 for the same.
