What is the primary advantage of using cement backer board?

The primary advantage of using cement backer board is that it provides a moisture-resistant surface for tile installation. This characteristic is crucial in areas prone to moisture, such as kitchens and bathrooms, because it helps prevent water damage and mold growth. Cement backer board acts as a barrier, making it an ideal substrate for tile applications, particularly with ceramic or stone tiles, which need a stable and durable surface.

The moisture resistance of cement backer board compared to other materials, such as drywall, is significant because it maintains the integrity of the tile installation over time. In situations where water exposure is a concern, using a material that can withstand humidity and direct contact with water is essential for ensuring a long-lasting finish. This quality makes cement backer board the standard choice among professionals when preparing surfaces for tile installations in wet environments.
