Floor tile patterns are not restricted by any rules. As long as the tiles fit into the design, you can lay out your tiles in any pattern you'd like. Basic tile layout places all the vertical and horizontal seams in line with each other. A common and relatively simple tile pattern to lay out is the brick pattern. The brick pattern breaks up the vertical seams in a fashion similar to a brick wall. The brick pattern requires that you use square or rectangular tiles.
Cut a few tiles in half for edges and corners, using a tile cutting saw. Cut additional tiles as needed during the installation.
Spread premixed thin-set with the trowel over a section of the floor or wall large enough to start two or three rows. Drag the notched edge of the trowel over the thin-set to leave 1/4-inch grooves.
Lay out the first row with full tiles. Position rectangular tiles so the long edge runs from side to side. Press the tiles into the thin-set, and insert a tile spacer between each joining edge.
Start the second row with a half-tile positioned adjacent to the edge of the structure. Lay out the second row with the tiles moving in the same direction. The half-tile will space the tiles in such a way that the vertical seam will be disrupted.
Repeat the process, alternating from a full tile starting one row to a half-tile starting the next. Spread more thin-set as needed to complete the wall or floor installation. Allow the thin-set to dry according to the times listed on the container.
Spread premixed grout over the gaps between the tiles, using the flat edge of a trowel. Pull the trowel across the seams to press the grout into the gap. Clean the excess grout off the tile with a sponge dipped in a bucket of water.
Apply more grout until all the grout lines are complete. Allow the grout to dry for a minimum of 72 hours before exposing the material to moisture or sealants.
