  • In the case of renovating old, self-protected bituminous waterproofing with slate or mineral granules, it can be used as a primer before applying the new bituminous waterproofing system. In bonded systems, the bituminous sheet is welded in its entirety, so the entire surface must be primed. In non-bonded or floating systems, the bituminous sheet is only welded at the singular points (parapets, drains, expansion joints, etc.), and these elements must be primed.
  • Primer and preparation of surfaces where a bituminous sheet is to be welded, on both porous and non-porous surfaces.
  • Priming and preparation of porous surfaces that will later be waterproofed or treated with asphalt products.
  • Protection from dampness in walls and partition walls.
  • Dampness protection of the external surface of concrete retaining walls and buried foundations, acting on the side in contact with the ground.
  • Production of asphalt mortars for screeding on asphalt waterproofing.

Advantages & Benefits

  • High film thickness.
  • Good durability.
  • Good chemical resistance to saline water and weak acids and even weak bases.
  • Doughy consistency.
  • Asphalt mortars are less rigid and more plastic than conventional mortars.
  • A paste-like product with a uniform appearance and cold application that hardens by evaporation of the water it contains. Once applied and dried, it forms a continuous film.
  • Little thermal variation.
  • Solvent free.
  • Easy application.
  • Great bonding.
  • Insoluble once the film dries.
  • Asphalt mortars have the advantage over conventional mortars in that they put less stress on bituminous waterproofing.
