For the first time tiler, drilling into tiles may seem a bit daunting and after all of the planning and preparing, what you don’t want is a cracked tile caused by a drifting drill bit. However before you start, try looking for some alternatives. You may be able to find the same size and colour tile that already has bathroom fittings in place i.e soap dishes, toilet-roll holders, towel rings etc.
Fixing an accessory tile
Decide where you would like the accessory tile to go so you can leave a space. Once all the tiles have been fixed, clean the remaining adhesive from the area you would like the accessory tile to go and leave for 24 hours. When ready apply fresh adhesive to the accessory tile press into place then use masking tape to hold until the adhesive is dry.
Drilling into tiles
If drilling is your only option, first try tapping the point of a masonry bit to break the glaze on the tile, you can also buy a tile bit that should cut through the glaze. Another way to make drilling easier is to place masking tape on the area that you want to drill, you can also buy a fitting that will make drilling more accurate. The dust from the tile may discolour the adjacent grouting so keep a cloth or hoover handy. Be careful not to put the screws in to tight as you may end up cracking the accessory tile.
Once all the tiles are in place leave for at least 24 hours then start grouting. You can buy in the form of powder which you mix with water or you can get ready mixed. When grouting in the kitchen or bathroom be sure to get waterproof. Apply the grout covering about 1sq metre and well into the tile joints using a damp cloth, with a separate damp cloth wipe the excess grout before it dries on the tiles. To finish you may want to polish for a shining effect.
If you find the grouting becomes discoloured there are whitening products available. Make sure you clean the area well and leave to dry, remember to read the instructions as some products are not suitable for waterproof grout.
