Product Description
PROOF is a one-component, low-viscosity, polyurethane-based liquid waterproofing and protection material. It is an economical system. It cures with atmospheric moisture and adheres strongly to almost any type of surface, forming a highly elastic film.
Its formulation is based on pure elastomeric hydrophobic polyurethane resin and special inorganic fillers, which give the material excellent chemical, mechanical and thermal resistance.
It is applied in two coats by brush, roller or airless spray machine. The minimum total consumption is 1.2-1.5 kg/m².
Application Areas
- Gypsum and cement panels
- Ceramic tiles (under the covering)
- Bathrooms
- Roofs
- Lightweight roofs made of metal or fibre cement
- Asphalt membranes
Advantages
- Although it does not require thinning, SOLVENT can be used depending on the conditions.
- As the white colour reflects most of the solar energy, it significantly reduces the internal temperature of the building.
- Has excellent thermal resistance; the product never softens. Maximum service temperature is 80°C, maximum shock temperature is 200°C.
- Resistant to cold: the film retains its elasticity down to -40°C.
- Its mechanical properties are excellent.
- Exhibits effective resistance to chemicals.
- Contains no toxic substances after curing.
- Effective in water vapour transmission: as the film breathes, no moisture accumulates beneath the coating.
Application
Apply the material in at least two coats with a roller or brush. Wait 6-24 hours between coats. If this time has been exceeded (for example, if more than 4 days have passed) or if you are not sure of the adhesion between coats, use AST-PU.
