Full Product Description
The weakest point in any concrete overlay or structural repair is the interface between the old and new material. Sikadur 32 eliminates this risk by creating a chemically bonded, high-strength connection that is physically stronger than the concrete itself.
When applied as a slurry coat to a prepared substrate, this epoxy penetrates the surface pores to form a dual mechanical and chemical bond with both the existing concrete and the fresh overlay. Its medium viscosity allows for easy brush or roller application on horizontal, vertical, and overhead surfaces.
Additionally, Sikadur 32 offers a generous “open time,” accommodating large-area pours between application and the placement of the new concrete. Because it is solvent-free, it is the preferred choice for structural bonding in cisterns, basements, and other confined industrial areas.
