Sikadur 32 — Low-Viscosity Two-Component Epoxy Bonding Agent for Concrete | Sika India (12 kg)

One of the most reliable epoxy bonding agents in Sika's product range, Sikadur 32 from Sika India is what structural repair teams and experienced waterproofing contractors reach for when they need a high-strength epoxy bond between old and new concrete — and need it to work even on damp surfaces. That last point is more important than it sounds. Most bonding agents require the substrate to be dry before application, which on a working construction or repair site is often an unrealistic condition. Sikadur 32 is formulated to bond effectively on damp concrete — giving applicators a practical advantage that reduces delays and removes one of the most common reasons repair bonds underperform.

It's a two-component, solvent-free epoxy with a deliberately low viscosity — which means it penetrates into the prepared concrete surface rather than just sitting on top of it. That penetration is what creates the genuine mechanical and chemical interlocking between the substrate and the new material applied over the top. For concrete crack repair patching, bonding repair mortars to deteriorated concrete sections, sealing construction joints, or preparing any surface where the bond between old and new concrete needs to carry structural load — Sikadur 32 creates the connection that holds.

The low viscosity also makes application cleaner and easier. Brush application is straightforward, coverage is good, and the working time is long enough to apply and then proceed with the repair or topping without rushing. For waterproofing contractors and repair applicators managing multiple elements on a site, that workability matters as much as the strength.

Backed by Sika's globally trusted construction chemical expertise and the Sikadur range's long track record on Indian infrastructure, industrial, and building repair projects — Sikadur 32 is a structural epoxy bonding agent that delivers every time the repair demands a permanent solution.
