Tile Installation

Subfloor preperation is the most important step in floor covering installation. The subfloor must be structurally sound, flat, and free of dirt, oily films, cracks and crevices.

Floor Layout

In this step, the room is squared off and measured, and the chalk lines are used as a guide. Once the chalk lines are in place, the installer will verify the floor in both directions to balance the room.

Tile Layout

Slight tone variations are to be expected from tile to tile. A good installer will prevent this from becoming a problem by mixing the tiles from several cartons before installation. This blends the tiles together, and any shade variations add to the character of the floor.

Spreading the Thinset

Using the chalk lines as a guide, the installer will begin applying the thinset in one section at a time. He will spread one coat using the flat side of the trowel and then immediately come back with a second coat, using the notched side of the trowel.

Laying the Tile

The tiles are then placed one at a time in the thinset by twisting and pressing while allowing appropriate spacing for the grout. A straight edge or spacers may be used to align the tile.

Grouting

The installer will generally begin grouting the following day. It is important to allow the thinset enough time to set up before applying the grout. The grout is spread by means of a rubber float or a squeegee. The tile is rinsed using a damp sponge.
