Versatile and flexible, SubSeal liquid membrane is an elastomeric waterproofing membrane for interior and exterior applications of hard surface flooring. This one-part, ready-to-use membrane covers all bases as a sealant, stand-alone crack suppressant and moisture barrier for horizontal and vertical applications.

SubSeal is a one-part, ready-to-use elastomeric waterproofing membrane designed for horizontal and vertical applications. It also functions as a sealant, stand-alone crack suppressant and moisture barrier. SubSeal bonds to the substrate, metal drains, PVC, ABS fixtures, stainless steel, concrete backer board and more, while featuring simple application, fast drying and same day tile installation.

When SubSeal cures, it forms a thin, flexible layer that becomes an impervious barrier to water intrusion. The membrane bonds to the substrate while creating a new surface capable of accommodating A118.4 or better latex mortars, organic adhesives and solvent-free epoxy setting materials.

  • Easily applied by trowel, roller, brush or sprayer
  • Thin and low profile, yet maintains superior flexibility when cured
  • Suitable for interior and exterior use (Including decks, restaurants, showers, lavatories, kitchens, spa areas, parking decks and more!)
