Bituminous Membranes

HYPERDESMO® PB-2K

Download Technical Data Sheet

HYPERDESMO® PB-2K is a fast-curing, two-component, bitumen-extended polyurethane fluid.  It produces a highly elastic membrane with strong adhesion to many types of surfaces and excellent mechanical and chemical resistance properties. It is based on pure elastomeric hydrophobic polyurethane resin and is extended with chemically polymerised virgin bitumen. Apply with brush, roller, spatula or airless spraying. Minimum consumption: 1.5-2.0 lt/m2.

For waterproofing and protection of:

  • Gypsum and cement boards,
  • polyurethane insulation foams,
  • asphalt membranes,
  • EPDM membranes,
  • bathrooms (under tiles),
  • verandas and balconies (under tiles),
  • flower pots and roof-top gardens,
  • roofs,
  • light roofing made of metal or fibrous cement,
  • non-potable water tanks,
  • basements,
  • foundations,
  • bridge platforms,
  • “cut-and-cover” tunnels,
  • irrigation channels.

It is a quick-curing, one component, thixotropic, bitumen-extended polyurethane fluid.   It produces a hydrophobic, elastic membrane with very strong adhesion to most types of substrates, as well as bituminous, and excellent mechanical and chemical resistance properties. Minimum total consumption of 1.5 kg/m2.

It is ideal for application on vertical surfaces: No running, no bubbling.

  • Gypsum and cement boards,
  • structural foundations,
  • roofs,
  • light roofing made of metal or fibrous cement,
  • asphalt membranes,
  • basements,
  • car parks,
  • closed spaces with high humidity,
  • cementitious substrates.
 

HYPERDESMO® 760 Bitum

Download Technical Data Sheet

A one component, slightly thixotropic, polyurethane liquid which cures quickly with the humidity in the atmosphere to produce an elastic membrane with strong adhesion to many types of surfaces (whether level, inclined or vertical). It is ideal for foundations and below grade walls as it combines effectively waterproofing with crack-bridging and humidity barring.

It is based on pure, hydrophobic, polyurethane resin and virgin bitumen, which result in excellent waterproofing properties. Apply with brush, roller or airless spraying in two coats with minimum total consumption of 1.0-1.2 kg/m2.

NOT recommended for exposed use.

For waterproofing and protection of:

  • Bathrooms,
  • verandas and balconies (under tile),
  • flower pots,
  • basements,
  • below grade walls,
  • non-exposed above grade walls and cement surfaces.
