PRODUCT: Epoxy Primer, Clear Waterbased 1-Part Penetrating Primer (formerly Uniseal Primer). For concrete or asphalt. Penetrates and seals porous substrates to improve adhesion of topcoats. Dries Semi-Clear. 5-Gallon Pail. Price/Pail. (aka gaf # 890543000; shipping leadtime 2-4 business days)
APPLICATIONS: Epoxy Primer is a clear, single-component epoxy primer/sealer designed to penetrate and seal porous substrates and to improve the adhesion of topcoats. Suitable for most surfaces including concrete, wood, fiberglass, steel, aluminum or asphaltic surfaces.
Although primer will greatly enhance the adhesion of various topcoats over metal surfaces, it is not designed to add to the corrosion resistance of the system, beyond what the topcoat provides.
Epoxy Primer will effectively solidify punky or chalky concrete, masonry or roofing surfaces when used as a primer prior to topcoating.
Epoxy Primer is an excellent primer for elastomeric roof coatings being applied over various surfaces.
Primer will amber slightly when used on exterior surfaces without a topcoat.
Can be used on its own as a transparent sealer over interior concrete floors to provide dustproofing and enhanced cleanability characteristics.
The following are approximate application rates:
