There are several things to consider before beginning your tile flooring job to guarantee that your flooring is attractive and long-lasting. First, during installation, you must install tile flooring on a subflooring known as the backer board for optimal installation. The backer board is a sub-material used in various construction projects, the most common of which are tile constructions. Unlike plywood and other wood substrates that could warp, the backer board is rigid and flat, so it will not buckle. Here’s what you need to know about a backer board to help you understand.

What exactly is a backer board?

Backer boards refer to prefabricated sheets (often made of cement-based materials) affixed to walls and floors to produce a solid basis upon which you can put tiles. The backer board is a tile substrate material and is typically available in 6mm and 12mm, with the former for floors and the latter for walls.

Backer boards, also known as cement boards, don’t have organic materials, such as wood, so they do not rot or degrade over time or when exposed to moisture. Therefore, they are applicable in wet rooms, such as kitchens and bathrooms, or at entry points into a space where rain and wet shoes might bring moisture in.

Backer sheets are great for waterproofing. This is because they consist of non-organic materials. Therefore, you do not have to worry about water infiltration, distortion, or weakening.

They can support far more weight than plasterboards, making them excellent for tiled wall surfaces. In addition, they make it much easier to tile and plaster on a smooth, flat surface, thus saving time and ensuring a high-quality finish.

Tile backer boards are also excellent for insulation in moist rooms and enhancing underfloor heating efficiency. Purchasing a thick board for your underfloor heating increases the level of insulation. This then enhances heat retention and significantly lowers the cost of heating your home.

Where do you use backer boards?

The backer board serves as the base for the material, in this case, tile. Backer board should be on all tile projects, including:
