Before putting down tile, you need to do vital prep work to ensure that the floors are ready for your new flooring. Otherwise, your tile will look uneven or won’t even lay down properly. Tile underlayment is the process of preparing the subfloor for your tiles. There are a few different types of underlayment that you can choose from, so here is a quick guide to help you decide.
Sheet Type Underlayment
The first type of tile floor underlayment is sheet type or backer board. Sheet type underlayment is a rigid material made of a combination of cement, crushed glass, and fiberglass. Professionals then attach this to the subfloor using screws and adhesive. The installation process is complicated, but this type of underlayment is the sturdiest.
Semi-Liquid Underlayment
If all you need to do is smooth out some bumps and gaps in your subfloor, then liquid or semi-liquid options such as mortar are a simple option for underlayment. You can apply these products with a trowel or roller. However, mixing liquid underlayment to the right consistency and applying the product properly is a difficult process, so this type is best left to a professional.
Membranes
Membranes are a type of tile underlayment that is similar to backer board. However, membranes are flexible sheets that are a bit easier to customize to the shape and size of your room. Most membranes offer waterproof protection as well, making them ideal for bathrooms.
These are your major options when installing a tile underlayment.
