Questions and answers
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.
Can I tile directly over drywall?
Tiling directly over drywall is not recommended in wet areas, as drywall is susceptible to moisture damage. Using a cement or tile backer board is advised.
What is the purpose of applying a primer or sealer before tiling?
Primers and sealers improve adhesion of tiles and thinset mortar on porous surfaces and prevent moisture penetration that can cause damage.
How do I prepare walls properly before tiling?
Ensure walls are clean, dry, smooth, and free of debris. Install a tile backer or cement board where needed and apply primer or sealer for porous surfaces.
