How to Apply:
- Planning your layout is essential. Choose your starting point to create a balanced visual appearance. Trowelling should be done horizontally. Spread the adhesive on to the wall, working on small areas at a time. Tiles must be fixed before the surface of the adhesive forms a skin. The tile is then adjusted to its final position with an up & down movement so that full coverage is obtained to the back of the tile.
- The size of trowel used should be approximately as mentioned.
- Add 25 kg of “MYMIX ‐ STA (Stone Tile Adhesive)” to approx. 6.5 litres. To 7.5 litres. Of cool and clean tap water and stir properly for 5 minute by hand or an electric stirrer to get a smooth and homogeneous mixture.
- After stirring wait for 10 minutes, stir once again and apply the adhesive on the subfloor with the recommended adhesive notch trowel
- Press the tiles within 15 to 20 minutes with a shuffling movement in to the adhesive. Check regularly to ensure that the back of the tile is in full contact with the adhesive. Remove excess adhesive immediately from the joints
- The proper preparation of the surface will make the fixing easier and quicker ensuring a better finish. The surface should be flat with a tolerance of 4mm over a distance of 2 meters. It is essential to waterproof wet areas prior to tiling
- New concrete is recommended to be 1 month old for every 25mm thickness and completely dried before tiling.
- Under normal circumstances, i.e. a temperature of 20°C and a relative humidity of 65%, the joints may be filled after minimum 24 hours.
