Product Description
PROOF MY cures with the moisture in the air and adheres strongly to almost any type of surface, forming a highly elastic film. It is a UV-resistant product.
It 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, bathrooms
- Verandas and balconies, roofs
- Lightweight roofs made of metal or fibre cement
- Asphalt membranes, EPDM membranes
- Stadium stands, car parks
- Bridge platforms, irrigation channels
Advantages
- Adheres perfectly to almost all types of surfaces, whether or not a primer is used.
- Does not require thinning.
- Has excellent weather and UV resistance. Since the white colour reflects a large part of the solar energy, it significantly reduces the internal temperature of the building.
- Thermal resistance is excellent; 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.
- Has excellent mechanical properties: high tensile, tear and abrasion strength.
- Shows effective resistance to chemicals.
- Contains no toxic substances after curing.
- Effective in water vapour permeability: as the film breathes, no moisture accumulates beneath the coating.
Application
Apply the material with a roller or brush in at least two coats. 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 unsure of the adhesion between coats, use AST-PU.
