Tilefast Regular off white-powder composed of cement, fine graded sand adhesive – Technical Data Sheet.

Description
Tilefast Regular is an off white powder composed of cement, fine graded sands and other special additives. When mixed with water, it becomes a mortar that has good bonding strength and is easy to trowel.

Precautions

Tilefast Regular is unsuitable for:

*
bonding moisture sensitive green marble;
*
bonding to painted walls;
*
substrates subject to constant water immersion such as swimming pools.

Surface Preparation

All surfaces to be tiled must be flat and true, free from oil, dirt, grease or any other contaminants. Very porous surfaces should be primed with Plastinex (1 part Plastinex mixed with 4 parts water).

Concrete : New concrete must be allowed to cure for 6 weeks and should have a wood flat finish. When finished with a steel trowel concrete must be acid etched, using Floor Prep.
Cement Render : Render to be left with a wood float finish and allowed to cure for 7 days.
Mixing Tilefast Regular
Add Tilefast Regular to clean water at a ratio of 20 kg to 5 litres of water. Mix product to a smooth paste free from lumps by using a drill that has a speed lower than 300 rpm, or mix by hand. Slacken the adhesive and   re-mix after 5 minutes.
Pot Life
Tilefast Regular has a pot life of approximately 4 hours at 20oC and 50% relative humidity.

Open Time

Tilefast Regular has an open time of approximately 20 minutes, which can be shortened to just a few minutes by the action of sun, wind, high temperatures or highly absorbent surfaces. Tilers need to constantly check that the adhesive has not formed a surface skin and is still fresh to the touch.

Wetting or priming the substrate prior to tiling prolongs the open time of the adhesive. It is not advisable to wet the adhesive when it has formed a skin as water only increases the rate of cement hydration and will result in an anti adhesive film. Skinned adhesive must always be removed and disposed of.

Application

Always install the tiles in accordance with AS 3958 1:1991 and ensure the backs of the tiles are free of dust. Spread Tilefast Regular evenly across one square metre at a time with a 6 x 6 x 6 notched trowel for walls or a 10 x 10 x 10 notched trowel for floors. The choice of trowel should be governed by the depth of the knobs, grooves or ridges on the back of the tile and the evenness of the substrate.

Lay the tiles with a fair pressure and at right angles to the notched pattern.

The final bed of adhesive should be between 2mm and 4mm. Wall tiles should have a finished joint width of 2mm – 4mm and floor files a finished joint width of 3mm – 6mm. Tiles can be adjusted for approximately 45 minutes after laying.

Coverage

20 kgs of Tilefast Regular will cover approximately 5 – 7 square metres with a 10mm notched trowel for floors and/or 8 – 9 square metres with a 6mm notched trowel.

Dry Time.

Tilefast Regular dries in approximately 24 hours at 23oC and 50% relative humidity. It may require longer times to cure for denser tiles and substrates or at installation temperatures below 10oC.

Expansion Joints

Joint Grouting

Grouting may commence after approximately 24 hours (depending on variables such as sun, heat, wind, etc.)

Shelf Life

Tilefast Regular can be stored in the original packaging in a dry elevated position for 12 months.

Packaging

Tilefast Regular is available in 20kg paper sacks.
