RIW Liquid GM - Gas Resistant Coating System
Verified by manufacturer 2 months ago
Liquid GM is a gas resistant coating system based on a single component water based compound, formulated on styrene-butadiene co-polymer.
Application
Specifically designed for a range of vertical and horizontal surfaces:
- Applied to walls, floors or soffits;
- As a retro applied gas proof membrane to concrete, masonry and brick substrates;
- As an alternative to sheet membranes in new construction.
Description
A single component water based compound, formulated on styrene-butadiene co-polymer. The product offers a high performance elastomeric liquid rubber membrane which only requires mixing to provide a waterproof and gas proof, liquid applied, methane and carbon dioxide barrier.
Features and benefits:
- Good chemical resistance to gasoline, sodium hydroxide, calcium chloride, de-icing salts and effluent.
- Excellent adhesion, fully bonds to porous and nonporous substrates.
- Rapid drying.
- Can be applied to damp and ‘green’ substrates.
- Flexible and non-toxic when cured.
- Can withstand temporary light trafficking.
- Easily repaired by locally over-coating.
- Can be painted, plastered or screeded over.
- Subject to normal conditions of use, the product will last the lifetime of the structure.
- Liquid applied.
- Easily applied by brush, roller or airless spray.
- Good UV resistance.
