Prime plasterboard with a suitable primer-sealer or diluted PVA solution before tiling to ensure the adhesive bonds well. This creates a consistent surface, reducing the risk of tiles coming loose. Apply the primer or PVA solution evenly and allow it to dry completely before proceeding with the tiling process.

FAQs & Answers

  1. Why should I prime plasterboard before tiling? Priming plasterboard before tiling creates a consistent surface that improves adhesive bonding, reducing the risk of tiles coming loose.
  2. Can I use PVA instead of primer on plasterboard before tiling? Yes, a diluted PVA solution can be used as a primer-sealer on plasterboard before tiling, but it should be applied evenly and allowed to dry completely.
  3. How long should I wait for the primer to dry before tiling? You should wait until the primer or PVA solution is completely dry before starting the tiling process to ensure optimal adhesion.
