Fosroc Nitocote ET 402 — Two-Component Epoxy Tar Protective Coating for Concrete & Tanks (10 L)

Not every project calls for the heaviest-duty system on the market — but every project still deserves a protective coating for concrete that genuinely performs. That's the space Nitocote ET 402 occupies in Fosroc's trusted Nitocote range. It's a two-component epoxy tar waterproofing coating that gives concrete and steel structures reliable chemical and moisture protection across a wide range of applications — without overspecifying for situations where a balanced, well-proven waterproofing chemical is exactly what the project needs.

The epoxy tar combination does what it's always done well — dense film formation, strong substrate adhesion, and a barrier that resists water immersion, mild chemical attack, and biological activity without breaking down. Water tanks, sewage structures, underground drainage, retaining walls in damp ground conditions, industrial floor protection — ET 402 handles these applications with a consistency that waterproofing contractors working across varied project types genuinely value. You don't have to second-guess it once it's on.

What makes this coating a practical choice is that it sits in the right part of the performance curve for the majority of infrastructure protection requirements. Too light and you're back dealing with the same moisture and chemical ingress problems within a few years. Too heavy and you're spending on performance you don't actually need. ET 402 lands in the middle of that range — and for most basement waterproofing, tank lining, and buried concrete protection applications, that's exactly where you want to be.

Apply it by brush, roller, or spray over properly prepared and primed surfaces. Two coats, proper film build, and you have a waterproofing solution that earns its keep for the full lifecycle of the structure — backed by Fosroc's globally trusted construction chemical standards and the Nitocote range's long track record on serious projects across India.
