    FAQs

    CAN I TILE OVER POLYURETHANE WATERPROOFING MEMBRANES?  WHAT DO I USE?

    Bostik has developed a system for tiling directly over our Dampfix PU solvent based polyurethane membrane. This system involves applying Specialist Primer over the membrane, and then using Asaflex as the tile adhesive. Consult the Technical Data Sheets for these products, or Bostik Smart Help for more information.

    WHAT SIZE NOTCH TROWEL DO I USE FOR THE TILE I’VE CHOSEN?

    As a guide, it is recommended to use a 6mm notch for tiles up to 150x150mm, a 10mm notch for up to 250x250mm and a 12mm notch for 300x300mm tiles.  Tiles 400x400mm and larger should be back-buttered in addition to using a 12mm notched trowel

    WHAT PRODUCTS CAN I USE WITH NATURAL STONE? WHAT IS ‘MOISTURE STABLE STONE’?

    Natural stone contains capillaries and pores within its structure. The size and quantity of these will influence the way water is absorbed. As water is absorbed by the stone it can cause the stone to warp and bend.  Moisture stable stone has a structure which does not result in any deformation of the stone. It is said to be moisture stable.

    DO I NEED TO PRIME FIRST?  

    Priming helps improve the consistency of the substrate, making it more accepting of waterproofing membrane therefore enhancing the bond between substrate and membrane and improves the bond between substrate and membrane.  A well primed surface can also improve the coverage of waterproofing membranes.
