Add spacers in between each of the floor tiles to ensure even grout lines. As you’re hanging up the tiles, position plastic spacers in between them to make room for the grout later. The spacers fit between the marble tiles and stick into the adhesive. Some tiles have built-in spacers. Be sure to check yours before you buy spacers.

Cut your tiles with a wet saw or nippers. Gather all of the wall tiles that you marked with the wax crayon during your dry-lay, and measure the length again to ensure that it’s in the right position. Put on a pair of safety goggles and carefully align the tile with the blade of the wet saw or the shears of the nippers. Then, move the tile through the blade or close the nippers to cut the tiles.

For large tiles, you may need to rent a polished tile-cutting saw, also called a wet saw, from a local home and garden store. You can cut tiles smaller than 2 inches (5.1 cm) with nippers, which are shears that are used for cutting small pieces of glass.

Hang edge tiles by applying adhesive to the backs of the wood tiles. Take a tile for the edge of the wall and apply the adhesive to the back, as if you were putting butter on a piece of toast. Then, position the tiles where it needs to go, and add the spacers. If the tiles design has been cut, make sure you’re placing it in the right spot.

If your ceramic tiles fit perfectly in the space and you don’t need to cut any of them, you should still use this method to do the outer columns and the top and bottom rows. This prevents the adhesive from getting on other surfaces or the pre-layed tiles.
