- A factory made bagged cementitious powder, containing Portland cement and silica sand, it can be mixed with water for installing small and medium size ceramic floor tiles in interior areas using the thinset method of installation.
- Approx. 55-60 sq. ft. per 20 kg bag with a ¼” x ¼” (6mmx6mm) square notch trowel for a bed of 3mm.
- Ideal for fixing ceramic tiles on Only floor
Smooth & Creamy
The surface to be covered with Ceramic tile shall be sound and confirm to good design, rigid, clean and free of dirt, oil, grease, curing compounds, form release agents or loose plaster and paint. For economy the surfaces should be level and true with in:
Walls – 3mm in 2.5m
Floors – 1.5mm in 1.0m
a) If a plaster/leveling mortar bed is applied, ensure that it is cured for at least 7 days to achieve proper strength before application of tile adhesive for installation of tile.
b) Ensure the substrate is clean and free from impurities like dust, dirt, debris, oil, grease, curing agents, loose plaster etc.
c) Dampen the wall before application of thin set adhesive
d) Clean the back of tile for any dust or coating.
The products can be mixed by hand or slow speed electric drill mixer (less than 300 rpm).
Pour potable clean water in a clean container and then add the powder NSA-309 and mix until the mixture becomes creamy and plastic. Do not over mix. Leave the mix to slake for 5-10 min and remix before use. Mix only sufficient quantity of adhesive for immediate need.
Proportion: Approximately 1 bag of NSA-309 with 5-6 ltrs of water. Adjust quantity of liquid to obtain proper consistency.
Wet the surface and remove the excess water before applying the adhesive. Ensure the area is shaded from sunlight. The adhesive shall be applied with the flat side of the trowel using a scraping motion to work the material into good contact with the surface to be covered. Additional mortar is then applied with the notched edge of the trowel.
When installing large tiles, spread adhesive onto back of tile in addition to trowelling material over surface to be tiled. Select proper type of notched trowel.
a) Thin Tiles upto size 300 X 300 mm (1’X1’), use a square notched trowel of size 6mm X 6mm to provide a total thickness of 3mm
b) Large Porcelain Tiles upto 450 X 450 mm with ribs, use a square notched trowel of size 6mm X 6mm and back butter the tiles with the same adhesive to a thickness of 1-1.5mm to provide a total thickness of 4.5mm
c) Large Porcelain Tiles upto 600 X 600 mm (2’X2’) with ribs, use a square notched trowel of size 6mm X 9mm and back butter the tiles with the same adhesive to a thickness of 1-1.5mm to provide a total thickness of 6mm
The most important standard to keep in mind is to insure that the piece of tile is completely bedded in the mortar or adhesive with 100% coverage.
Rear face of tiles (especially Porcelain tiles) should be cleaned with damp sponge to clean all the dust. Do not saturate in water.
Excess mortar on adhesive shall be cleaned from the surface of the stone with wet cloth or sponge while the mortar is fresh.
