Product Details

ALSEAL AS-2507 Epoxy Moisture Barrier

ALSEAL AS-2507 Epoxy Moisture Barrier is a solvent-free, low-odour, non-flammable, two-component epoxy coating developed to deliver powerful resistance against moisture and vapour transmission through concrete substrates.

Its 1:1 easy-mix ratio ensures precise blending and smooth application, forming a dense, impermeable membrane that prevents moisture-related flooring failures. This makes it an essential pre-treatment or primer layer for areas exposed to high humidity, subfloor dampness, or hydrostatic pressure.

Designed for both residential and commercial flooring systems, AS-2507 bonds to concrete, screeds, cementitious substrates, and stone, providing a strong base for subsequent layers like epoxy, polyurethane, or MS polymer adhesives.

By creating a permanent moisture seal, it protects timber and vinyl floors from bubbling, lifting, or debonding — ensuring long-lasting flooring performance. Trusted by professionals and available at The Waterproof Supplier, it’s the reliable choice for pre-floor moisture protection

Product Limitations

Not recommended for applications below 10 °C or above 85% humidity. AS-2507 is not a trafficable surface and must be covered with conventional floor or wall tiles. AS-2507 may turn yellowish when exposed to sunlight or UV light over time.
