Boscoseal PU Product Description
Boscoseal PU Liquid Polyurethane Waterproofing Membrane is a ready-to-use, single-component, moisture-curing, bitumen-modified polyurethane membrane that is free from coal tar. Once cured, the membrane forms a highly flexible, durable, and waterproof barrier.
Product Key Features (SMART ADVANTAGES)
Ready-to-use, single-component product
Non-toxic and formulated to be hydrocarbon-free
Can be applied in a single coat on horizontal and sloped surfaces
Provides excellent continuous adhesion to concrete, helping prevent lateral water migration
Capable of bridging substrate cracks up to 2 mm wide
Excellent environmentally friendly properties and non-polluting
Does not become brittle with age
Easy to apply without requiring special equipment
Product Description (DESCRIPTION)
Boscoseal PU is a ready-to-use, single-component polyurethane waterproofing membrane with moisture-curing properties (Moisture Curing Polyurethane Membrane). Once fully cured, it forms a highly flexible, strong, and impermeable membrane that effectively prevents moisture penetration.
Boscoseal PU is designed for application on both horizontal and vertical surfaces. The waterproofing membrane can be protected with a protective screed, render, or an overcoat of Boscoseal Top Coat.
Suitable for application using a brush, roller, trowel, or spray equipment.
Application areas include roofs, podium decks, balconies, planter boxes, concrete floors, elevated decks, outdoor terraces, bathrooms, inspection chambers, swimming pools, bridge decks, foundations, basements, and tunnels.
