Dural® 50

Description: A 100% solids, 2-component acrylated epoxy resin formulation. High strength. Penetrates cracks by gravity. Deep penetrating. Strengthens concrete surfaces. Heals and seals concrete. Contractor friendly. Does not contain Styrene or peroxides. Non-flammable. Moisture tolerant.

Application: Bridge decks; parking decks; consolidation of porous and dusting surfaces; reduce water absorption; reduce chloride penetration; pressure injection; gravity feed hairline cracks.

Coverage: Coverage rates are approximate and for estimating purposes only. Surface temperature, texture, and porosity will determine actual material requirements.
Slab Sealing: 100–200 ft²/gal. for first coat for typical concrete surface. 150–300 ft²/gal. for second coat in cases of extensive cracking or high porosity.
Crack Grouting: Coverage will be determined by depth and length of cracks.

Coverage:
For slab sealing: 100–200 ft²/gal. for first coat for normal concrete surfaces. 150–300 ft²/gal. for second coat where extensive cracking or porosity in concrete is present.
For crack grouting: Coverage depends on extent and depth of cracking.
