Questions and answers
Why is priming plaster important before tiling?
Priming plaster seals the surface to prevent it from absorbing moisture from the tile adhesive, ensuring stronger adhesion and longer-lasting tiles.
What type of primer should I use on plaster before tiling?
Use a suitable primer designed for porous surfaces like plaster, typically a PVA or acrylic-based primer, to effectively seal the surface.
Can I tile directly onto unprimed plaster?
