Description

A lightweight epoxy repair composite for rebuilding damaged vertical and overhead concrete and masonry surfaces. This high-build concrete repair mortar can be applied up to 12.7 cm (5 inches) thick on vertical surfaces and up to 7.6 cm (3 inches) thick on overhead surfaces without the need for support during the application or shuttering during cure.

This solvent-free, lightweight epoxy repair compound is non-porous and does not absorb water or chemicals. It provides excellent resistance to carbonation and can withstand extreme weather conditions.

Generally, concrete requires at least 28 days to cure. In comparison, Belzona 4141 (Magma-Build) achieves full mechanical cure at 25°C (77°F) within 12 hours and full chemical cure within three days.
