Hyperdesmo Classic®


Polyurethane liquid membrane for waterproofing & protection, easy application.


HYPERDESMO®-CLASSIC is a simple and economic solution for waterproofing and
protection. It is a one component, low viscosity, polyurethane fluid which cures with the humidity in the atmosphere to produce a highly elastic membrane with strong adhesion to many types of surfaces.
It is based on pure elastomeric hydrophobic
polyurethane resin plus special inorganic fillers,
which result in excellent mechanical, chemical,
thermal, UV and natural element resistance


Apply with brush, roller or airless spraying in two
coats. Minimum total consumption: 1.2-1.5


The product fulfills the EOTA requirements and is certified according to ETAG005.

features & benefits

  • No thinning is required but SOLVENT-01 may be used

  • Excellent weather and UV resistance. The white colour reflects much of the solar energy and so reduces the internal temperature of buildings

  • Excellent thermal resistance, the product never turns soft. Max service temperature 80°C, max
    shock temperature 200°C.

  • Resistance in the cold: The film remains elastic even down to -40°C

  • Excellent mechanical properties

  • good chemical resistance

  • non-toxic after curing

  • Water vapor transmission: The film breathes so there is no accumulation of humidity under the coat.



Apply the material with roller or brush in two, at least, coats. Leave 6-24 hours between coats. If more time passes (for example more than 4 days) or if you are unsure of the interlayer adhesion,
use Universal-Primer-2K-4060.
