Description
RIW Toughseal Epoxy Waterproof Coating
RIW Toughseal is a high-performance, solvent-free, two-part epoxy waterproof coating designed to provide a seamless barrier against water, water vapour, abrasion and chemical attack. Suitable for concrete, masonry and steel substrates, it creates a durable joint-free membrane for waterproofing basements, plant rooms, wet areas, ground floors and structural concrete where long-term protection is essential.
Its polymer-modified epoxy formulation delivers exceptional adhesion, outstanding durability and resistance to fresh water, salt water, dilute acids, alkalis and atmospheric exposure. Toughseal can also be dressed with aggregate to create a slip-resistant finish or provide a key for tiling, rendering and screeds, making it a versatile solution for both waterproofing and protective coating applications.
