Features and benefits:

  • Multi-purpose solution.
  • Resistant up to 9.5 bar of positive and negative pressure.
  • Excellent adhesion to the most common surfaces used in construction.
  • Solvent-free.
  • Once WATstop is dry it can be coated with plasters, skim coats, resins, glues, coatings, tiles or paints, because it also acts as an adhesion coadjutant.
  • Suitable substrates include concrete, structural masonry, ceramic, steel, screed, ferrous metal and polyvinyl chloride (PVC).
  • Guaranteed to resist weathering for up to ten years.
  • Can be applied by trowel in just one coat if applied in original state. If up to 40% water is added, can be applied by roller or brush in two coats (depending on the coverage).
