Liquid Membranes

HYPERDESMO® HAA

Hyperdesmo-HAA (Humidity Activated Accelerator) is made up of a single component polyurethane liquid membrane perfect for waterproofing in only one coat. This is perfect for reducing labour costs and allows for short working hours. This new product, now available, is based on the combination of the Hyperdesmo and Accelerator 3000. Formulating and mixing the Hyperdesmo with the Accelerator 3000 has allowed us to create a unique formula that cures rapidly and forms a completely defect free membrane with both mechanical and elastomeric properties. The Hyperdesmo-HAA is perfect for use in winter and in climates with fairly low humidity.

 

 

HYPERDESMO® CLASSIC

HYPERDESMO® 750

Download Technical Data Sheet

A one component, thixotropic, polyurethane liquid used as basecoat in under-tile or protected applications. It cures with the humidity in the atmosphere to produce a highly elastic membrane with strong adhesion to many types of surfaces.  Being thixotropic, it can easily be applied on vertical surfaces without running.  Also, due to its combination of high elongation and low modulus properties, it is highly effective when used for crack-bridging. It is based on pure, elastomeric, hydrophobic, polyurethane resin, which results in excellent waterproofing properties.

Easy application with brush, roller or airless spraying in one or two coats with minimum total consumption of 1.0-1.2 kg/m2.

Waterproofing and protection of:

  • Bathrooms,
  • verandas and balconies (under tile),
  • flower pots,
  • roofs (as basecoat),
  • basements, foundations (not a humidity barrier).
