Backer Board

What Is Backer Board?

Backer board is a specially designed underlayment used beneath tile to create a stable, durable surface for installation. Unlike drywall or plywood, backer board is engineered to resist moisture and maintain structural integrity in wet or high-humidity environments.

It is commonly installed in bathrooms, kitchens, showers, and flooring systems where tile requires a strong and consistent base. Backer board helps prevent tile cracking caused by substrate movement or moisture exposure.

Types of Backer Board

Backer boards are available in cement-based, fiber-cement, and lightweight foam-core options. Each type offers different benefits depending on application requirements, weight considerations, and installation conditions.

Benefits of Using Backer Board

Using backer board improves adhesion, increases durability, and extends the life of a tile installation. It also supports proper waterproofing when used with membranes or sealants.

Proper installation of backer board is essential for achieving professional, long-lasting tile results.
