Product details


VAPORTIGHT COAT®-SG2 is a unique 2-component, alkali resistant, moisture tolerant, extremely high density and chemically enhanced epoxy based product which prevents capillary infiltration of oil and other chemicals from the ground. Applied in one coat, SG2 reduces the passage of water vapor and moisture through slabs and walls, thus eliminating delamination of adhesives, floor coverings and coatings.
For a faster cure use SG2/3-ACCELERATOR and speed up cure times to 3 to 5 hours.
