Epoxy
Cureseal PW
Epoxy Cureseal PW is a three-component water-based epoxy primer and sealer designed for green, new, and existing concrete surfaces. Its low-viscosity penetrating formulation strengthens concrete substrates, improves adhesion of subsequent coatings, and acts as an effective curing membrane without requiring removal before overcoating. Certified for potable water contact, Epoxy Cureseal PW is ideally suited for water-retaining structures, concrete floors, screeds, reservoirs, and industrial concrete protection systems.
Available in 5L kit sizes.

Intended Uses
Epoxy Cureseal PW is specifically formulated to penetrate, seal, and stabilise concrete and cementitious substrates while providing an ideal foundation for subsequent coating systems. Unlike conventional curing compounds and sealers, it remains permanently incorporated into the substrate and can be directly overcoated. Its potable water certification makes it particularly valuable for reservoirs, water treatment facilities, potable water structures, and industrial concrete assets where both substrate preparation and regulatory compliance are required. The product also performs exceptionally well as a bonding agent for weak plaster and cement surfaces prior to resurfacing or painting.
