Waterproofing membrane for use on:
- Roofs;
- Protection of polyurethane foam insulation;
- Waterproofing and protection of concrete constructions.
Description
Liquid-applied, highly permanent elastic polyurethane membrane used for long-lasting waterproofing. Consists of flexible water-based polyurethane resins (dispersion).
Based on the innovative PUD-Technology of Maris Polymers SMSA.
Features and benefits:
- One-component, cold-applied and cold curing, water-based aromatic polyurethane.
- White/ light grey in colour.
- Simple application (roller or airless spray).
- Forms a hydrophobic, 100% waterproofing, seamless polyurethane membrane without joints or leak possibilities that protects old and new structures efficiently and on a long-term basis.
- When applied forms seamless membrane without joints.
- Crack bridging according to EN 14891.
- Maintains its mechanical properties over a temperature of -30 to +90°C.
- Provides water vapour permeability.
- The waterproofed surface can be walked on.
- Even if the membrane gets mechanically damages it can be easily repaired locally within minutes.
- In combination with top coat Mariseal 400W it offers long-lasting durability against UV and abrasion.
- Supplied in metal pails between 1 and 20 kg.
