If you plan to lay a new tile floor yourself, you will need to research how to install a tile underlayment first. The underlayment goes between the tiles and the sub floor to eliminate any irregularities in the sub floor, such as cracks, indentations, or curvatures. The underlayment is used to create a harder surface that won’t bow under the weight of a footfall.
Backer Board
This type of underlayment is ideal when you plan to install ceramic or porcelain tiles. It consists of 4′ x 8′ or 3′ x 5′ panels that are comprised of cement, fiberglass, and crushed glass particles. It’s installed by laying down a thin adhesive on top of the sub floor and pressing the boards into place. Once it has been set in place, the backer board is secured with screws.
Liquid Mortar
This option is used less frequently today than it was in the past because it takes experience and skill to perfect this method. It involves mixing mortar with water to create a near-solid consistency before pouring the solution over the sub floor. Once it has been evenly distributed, the tiles can be set into place.
Roll Out a Membrane
Another type of tile underlayment is a prefabricated membrane that you can cut to size and lay over the sub floor. It’s made from polyethylene, which helps to protect your tiles from water damage and cracking. A membrane is installed in the same way that a backer board is installed except that it’s flexible and easier to manipulate.
You can learn more about installing these types of underlayment from your stone and tile supplier. They can also provide you with the tools and resources you will need to achieve professional results.
