Ceramic Tile Installation Subfloor Thickness

I have visited several tile stores and received conflicting subfloor thickness requirements.

Ceramic tile installation subfloor thickness.

The subfloor must be structurally sound as well as thick and stable enough to hold the weight of the tile without moving or flexing. We are planning on using ceramic tile with granite counter tops. Preparing your subfloor for tile in this video learn how to prepare a wood or concrete subfloor for tile including such steps as checking for dips installing backerboard applying primer and thinset pouring liquid underlayment and when to use osb or exterior grade plywood. However you re not out of the woods.

1 inspect the floor from the basement or crawl space below it. Regardless of the material it must be at least 1. Osb panels provide an excellent base for many types of finished flooring including ceramic tiles if careful attention to the construction and preparation of the subfloor is paid in order to avoid costly callbacks. After completing the prep work the floor should measure 1 1 4 inch thick the recommended thickness for proper tile installation.

Because of issues of moisture movement and adhesion ceramic tile will work well with certain types of subfloor underlayment systems and can go dramatically wrong with other subfloor materials. This guide will show you how to prepare your subfloor for a tile installation project to ensure that it s fit to support ceramic or porcelain tile. Preparing a subfloor is an essential step for installing floor tile it provides a level surface that will allow the tiles to properly stay in place.

Most of the cabinets are on the perimeter on the room with a peninsula that runs to the center of the room 7 from the outside wall.

Always follow the manufacturer s installation. For this reason ceramic and porcelain tile floors can be considered somewhat delicate despite the inherent strength of the material.

Laying tile to veneer plywood risks loosening and unbonding the veneer creating an unstable base for the tile. The subfloor is 5 8 t g. Concrete expands and contracts and that type of movement can also crack the tiles and the grout.
