Customer Questions & Answers

  • Question: What is Mapei Keracaulk U Unsanded Caulk used for?

    Answer: Mapei Keracaulk U Unsanded Caulk is primarily used for sealing joints and gaps in ceramic tile installations.

  • Question: Can Mapei Keracaulk U Unsanded Caulk be painted?

    Answer: No, Mapei Keracaulk U Unsanded Caulk is not designed to be painted over. This product is formulated to remain its original color, which is alabaster, so users should consider matching the caulk color to their tiles or surrounding surfaces before application. However, it blends well with lighter-colored tiles, providing a seamless look that enhances aesthetics instead of detracting from it.
  • Question: Is Mapei Keracaulk U Unsanded Caulk waterproof?

    Answer: Yes, Mapei Keracaulk U Unsanded Caulk is waterproof once it has cured.

The waterproof feature helps protect materials from water damage and mold growth, keeping your installations safe and prolonging the lifespan of flooring and wall surfaces.
  • Question: How do I apply Mapei Keracaulk U Unsanded Caulk?

    Answer: To apply Mapei Keracaulk U Unsanded Caulk, first ensure that the surfaces are clean and dry. Use a caulk gun to evenly distribute the caulk into joints or gaps.

  • Question: Is Mapei Keracaulk U Unsanded Caulk suitable for outdoor use?
