Yes, you can use PVA (Polyvinyl Acetate) to seal plasterboard before tiling. Applying a coat of PVA to the surface ensures that the plasterboard doesn’t draw moisture from the tile adhesive. It acts as a primer, improving the adhesive’s effectiveness and helping prevent potential issues like tiles coming loose in the future. Make sure the PVA is diluted according to manufacturer recommendations and allow it to dry completely before starting to tile.
