3 Types of Underlayments to Study and Understand Before Working With Tile

Tile underlayment is the product put underneath the tile to prevent the grout and tile from bending and breaking. It also protects the subfloor from moisture. There are three primary forms to choose from, and a reliable tile tool company can help you determine which one is best for your particular project.

1. Trowel Underlayment

This type is considered pourable. Mortar is often used on top of concrete. The installer must apply it evenly and relatively thick. It takes practice to get a smooth, dense finish, but it is critical in order for the tile to lay correctly.

Thinset mortar is made from a different compound. Installers can use it on concrete or backer boards. Backer boards are large sheets that contractors adhere the tile to, and the panels can be used with or without thinset.

2. Backer Board

Backer boards are strong cement and fiberglass panels. To install, apply an adhesive and glue to the subfloor. In addition, the board may need to be screwed to the flooring. Next, lay the tile. This is the preferred material when laying porcelain or ceramic tiles.

3. Membranes

Many homeowners choose this tile underlayment because it is relatively easy to use. Membranes come in roll-out sheets, and the material will protect the tile and grout while making a water-resistant barrier. Manufacturers make membranes that are suitable for concrete or wooden subfloors, and you will want to use the sealants each company recommends. A tile industry expert can help you find the appropriate product for your subfloor and tile type.
