Subfloor Preparation For Tile

As with subfloor preparation making sure it is clean and free of any debris and adhesives is vital to ensuring the tile going over it will effectively bond to it.

Subfloor preparation for 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. It will break or dislodge if the surface bends under the load. In addition uncoupling tile membranes prevent moisture from infiltrating surfaces below. 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.

It uncouples or releases the bond between plywood and tile mortar allowing each surface to move independently of each other. Proper preparation of the subfloor is critical to the success of your ceramic tile installation. 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. These are some broad guidelines to ensure your subfloor is prepared for tiles but there can be other variables we didn t delve into in this post.

A plywood subfloor must be structurally sound and able to support the installation. Yes tile is great over slabs and in areas where moisture is present. For this reason ceramic and porcelain tile floors can be considered somewhat delicate despite the inherent strength of the material. Product when people think of flooring for bathrooms and basements the subfloor has to be considered.

In general the procedure for preliminary preparation of the subfloor involves the following steps. Cement backer board can provide a solid flat surface to install tiles on if you have a wood subfloor. It simply won t last. Wood building materials contract and expand at different rates from natural humidity and exposure.

You can repair cracked and damaged concrete with mortar and by using a grinder to flatten out ridges and bumps. Tile floors are heavy and tile is a hard material. Laying tile on plywood. If the subfloor flexes you can usually add more plywood and if it s moisture damaged you can replace the damaged sections.

A tight unmoving bond between mortar and subfloor causes cracking. An uncoupling membrane does exactly what the name says. However installing tile over a plywood floor is never recommended.
