Yes, you can use PVA on plasterboard before tiling. It's essential to apply a diluted PVA solution (mix of PVA glue and water) to the plasterboard. This primer layer helps to seal the surface, preventing the absorption of moisture from the tile adhesive and ensuring a better bond between the tiles and the plasterboard. Make sure the PVA mix is dry before starting to tile.

FAQs & Answers
