Ultra-Low Viscosity, Low Modulus, Fast Setting, Crack Healer-Sealer/Primer

DURAL 50 LM FS is a two-component, low modulus, 100% solids, fast setting epoxy resin formulation designed to penetrate concrete and seal it from the ingress of chlorides and water. DURAL 50 LM FS heals and seals hairline cracks through its penetration. The DURAL 50 LM FS can also be used as a fast setting primer for Epoxy Polymer Overlay Systems.
