Before tiling, apply a tile backer board or cement board to the walls. Additionally, ensure that surfaces are clean, dry, and free of debris. Use a primer or sealer on porous surfaces to improve adhesion and prevent moisture penetration. These steps provide a solid, even foundation that supports the weight of tiles and enhances durability.

FAQs & Answers

  1. Why should I use a backer board before tiling walls? A backer board provides a solid, stable surface that supports tile weight, prevents moisture damage, and helps ensure long-lasting tile adhesion.
