The wall should be strong and flat, surface be smooth. The wall should be waxed / printed. Wall should be clean and dry, if the tiling has to be done on plywood the surface of wall should be sealed with 50% volume mixture of PVA and water.
Mix the tiles with different cartons which help in fine blending of shades. Ample lighting should be provided. Each should be spread and mixed on the floor to check for any variation mixing of tiles brings harmony to shade by avoiding obvious patches. Prior to fixing. tiles should be immersed in water for 15 / 20 minutes
Apply a high quality ceramic adhesive on the wall andplace the first tiles on the corner.apply even pressure on the four corners of tiles to ensure adhesion of tiles to substrate.Cover the Area of wall that can be done without cutting tiles and leave it for at least 12 hours.Cover the rest of area with measured and cut tiles as per requirement.
To ensure the Proper contact of tiles with the wall, evenly temp the tile, tiles should be fixed on the bed by siding & tamping with wooden or rubber mallet.Spacers between the tiles should be between 2-5mm as per the usage & area of application.Remove spacers after 24 hours from laying the tiles
After 24 Hours Of Laying of tiles, the grouting is done. Always use good quality grout. Apply the grout diagonally between the tiles using a sponge to fill the gaps between the tiles, Fill the joints with grouts as directed by Grout manufactures, Clean and wipe the surplus grout with a sponge, or as indicated by manufactures.
To fill the around the curve surface of wash basin etc. measure and mark the curve on cardboard and place to cardboard on the tile to cut it.
To pass a pipe through the tile. the tile has to be cut in a specific manner. Mark it's position on the tile. Draw a straight line passing through the center of the circle. Cut the tile on the line drawn. Cut the semi-circle on each of the half. these two halves placed together
Tile has be cut in "L" shape for window recess. Cut a line from center to edge and then draw a right angle line vertically down. Cut the tile to get an "L" shape that can fit a window recess.
While Laying the normal tiles. keep an empty space where accessory tiles will fit. Apply the adhesive on the back of accessory tile and then place it uniformly in the space and apply even pressure to place the accessory tile.
Apply masking tape to cover the area to be drilling Mark the position of the hole and drill the hole with lowest possible pressure on the drill
