- Before tiling all surfaces must be tidied. That means also floors and walls. All surfaces should be straight and checked with a plumb or a straight stick. If surfaces are uneven, walls should be evened out with cement based mix and floors with cement. Before that all surfaces should be covered with a primer. This ensures that the cement or cement based mix sticks with the surface that was already there.
3. You should make sure that there is more than half a tile next to a wall. Tiling should be started from the second row and you can use a plumb or a straight carcass to support underneath. Mixture comb should be chosen according to tile size. There are different size mixture combs, choose a bigger comb for bigger tiles. To continue joints you can use joint crosses or joint string. An experienced worker can do it without joint crosses. There must be a joint string in every horisontal joint of a tile row.
4. After tiling the walls you must clean the floor (f.e. if mix has fallen down) and then cover it with a primer. After it has dried cover it with a mix that keeps water away and cover the corners that join floors and walls with a corner strengthener. The next day you can start tiling the floors. You should distribute the tiles the same way as with the walls. When tiling a floor, joint crosses should be used. If there is a discharge pipe you should leave the factory made side of a tile around it to avoid injuries to legs, toes etc. If that is not possible the sides you cut must be smoothened with sandpaper. If floor tiles have dried then you can tile the first row on the walls. After all tiles have dried you should joint the walls first and then the floor. Joint mix is pushed to the joints with a rubber spatula. Excess joint mix can be washed off with a damp sponge (not only the surface, but also the joints). Before washing you should let the joints dry for about half an hour (depending on the tiles, room temperature etc). Wash the tile surface properly! The next day all corners that join floors and walls must be tightened with sealant. When tiling you should use products from the same manufacturer to guarantee its warranty.
5. After learning the basics you definitely have a lot more questions, but a written manual is not enough to learn how to lay tiles.
