Product Overview: Neoproof Polyurea L

Neoproof Polyurea L is a high-performance, 2-component, pure aliphatic, brushable polyurea waterproofing coating designed for roofs. It provides exceptional mechanical durability and outstanding waterproofing properties. Not requiring special application equipment, this coating forms a blister-free, non-penetrating film that offers zero water absorption and remarkable resistance to UV radiation and mechanical stress.

Applications:

Roofs made of concrete, cement boards, mosaic, and cement slurries.
Rooftops requiring resistance to stagnant water.
Suitable for metallic surfaces after applying the proper primer (Neopox® Special Primer 1225 for anticorrosive protection).
Ideal for new or old polyurethane waterproofing layers.
Used as a top-coat over fast-setting sprayable aromatic polyurea.
Effective for the protection of polyurethane foam insulation.

Properties/Advantages:

Prevents moisture penetration, providing complete sealing.
Offers increased resistance to bending and stretching.
Very high mechanical strength.
No need for special application equipment.
Remarkable UV resistance.
Excellent bonding to various building substrates.
Blister-free coating with no appearance of holes during curing.
Quick drying and curing.
Long pot life.
Crack-bridging properties.
Easy application.
Long-lasting waterproofing protection.
Ideal for walkable roofs.
Resistant to temperatures from -35°C to +80°C.
