Important instructions for laying floor tiles 1 Prepare base mortar with cement and sand in the ratio of 1:4 2 The total mortar thickness should not be more than 1 Inch 3 Set the levels for the floor. ie.,, dead level or slop as specified by the Architect / Contractor 4 Prepare cement slurry with cement and water to form a thick paste and spread it on the leveled base mortar 5 Wet the rear side of the tile with water. (Complete immersion of tile is not necessary) 6 If tiles are square or rectangular in shape, set the right angles for the area and place the first tile along the right angle line on base mortar. Tap gently with the rubber 7 After laying, immediately clean the surface of the tiles with clean wet sponge. Ensure that the base mortar cement which squeezes through joints does not settle on the tile. 8 Also make sure that the water used is not hard or brackish 9 Do not use the area laid for 48 Hours 10 Fill the joints with pointing materials ie., mixture of white cement and desired color pigment. For higher quality of finishes, you could use, if required, a polymer based cementitious tiling joint filler. Do not apply the pointing material all over the surface. 11 Allow the pointing material to set for 15 minutes and clean the surface of the tile with clean wet sponge, in order to remove the excess pigment on the tile surface. 12 Wash the surface with soap water or mild detergent to get a clean surface.
