•  The surface on which the tiles are to be laid should be clean and free from dirt and dust particles to avoid contamination.

  • Tiles should be completely immersed in clean water for about 45 min. before using and should be laid as soon as the surface water has gone. Dry or partly dried tiles should be used. Wetting is recommended on dry floors. Soaking of tiles and wetting of floors are not required in case of laying with chemical adhesive.

  • For the new floors the mortar bed should be in the ratio of 1:3 cement to sand by volume.

  • Recommended thickness of mortar bed for a new floor is 1 inch to 1 ½ inch and an old existing mosaic or cement floors ½ inch is sufficient. The mix should be used within two hour of the addition of water and any mortar (mixture) not then used should be discard and not retampare.

  • Before laying floor tiles on old mosaic and cement floors, these should be chipped with a chisel or sharp tool so that the surface is sufficiently rough to grasp the mortar.

  • Slope on the surface on which tiles are fixed wherever required should be given for water drainage at the time of preparing the mortar bed.

  • Tiling should preferably be started from the centre area so that cut tiles, if any come only on the sides.

  • Before fixing tiles should be coated with a thin layer of cement slurry or tile fixing adhesive sufficient to cover grooves to have better grip and strength and also to avoid air pockets.

  • Tiles should be gently tapped after laying to ensure total mortar contact.

  • Bedding material between the joints should be cleaned with a brush before it drives. Thereafter allow 24 hours for tiles mortar compound to set properly and avoid walking.

  • Leave a grout joint of about 3-4 mm between two tiles. The gaps between tiles should be filled with white cement or white cement mixed with colors matching the tiles. These joints can also be filled with the chemical grout adhesives available in market.

  • After filling the joints floor surface4 be cleaned with sponge or a piece of cloth and filler now be allowed to set for 24 hours by avoiding all traffic.
