EX-74 is a clear, tough, high gloss surface coating formulated to produce a deep glass-like appearance in a single layer on a sealed surface. Two or more layers are often applied for added depth and protection.
EX-74 has been formulated with UV inhibitors to reduce the yellowing of epoxy coatings. EX-74 is not weather resistant and is not recommended for unprotected exterior use. Exterior use will cause a chalky surface requiring sanding and recoating to restore the glossy surface.
EX-74 has an extended "open time," which allows up to 25 minutes in the mixing container at 70º F and up to one hour working time on the coated surface—not recommended in freezing climates due to the possibility of de-lamination.
Always seal porous surfaces such as wood or canvas with a thin brushed layer of EX-74 before pouring a topcoat. See instructions in the link below for full details.
