Before tiling, use a polymer-modified primer to ensure better adhesion of the tiles to the substrate. This type of primer effectively seals pores and provides a firm, even base, enhancing the durability and longevity of your tiling job.

FAQs & Answers

  1. Why is a polymer-modified primer recommended before tiling? A polymer-modified primer seals pores and creates a firm, even base, improving tile adhesion and the overall durability of the tiling job.
  2. Can I use regular primer instead of polymer-modified primer for tiling? Regular primers may not provide the necessary adhesion and sealing properties needed for tiles to bond properly, so polymer-modified primers are preferred.
  3. How long should I wait after applying primer before tiling? Typically, you should wait for the primer to dry fully—usually between 1 to 4 hours—before proceeding with tiling to ensure optimal adhesion.
  4. Does the type of substrate affect the primer choice before tiling? Yes, different substrates may require specific primers; however, polymer-modified primers are generally versatile and effective on most common surfaces.
