Recommended Primers
Substrate

Recommended Primer

Aluminum/Galvanized Steel/Stainless Steel

B-875/T-63 or N-8564A/N-8564B Wash Primers and N-1088A/B, N-1981A/B or N-8901A/B Epoxy Primers.

Ductile or Gray Iron Castings

N-1981A/B, N-8901A/B or N-1088A/B

Plastics

Due to the wide variety of plastic/fiberglass substrates, system performance should be tested and confirmed on actual substrate.

Previously Painted Surfaces

Surface should be intact and sound. All loose and flaking material removed and bare spots primed with an appropriate primer. An area should be tested with the coating to assure compatibility.

Steel

N-5751M2 Zinc Rich Epoxy, N-1088A/B, N-1981A/B or N-8901A/B Epoxy Primers.

Wood

Due to the wide variety of wood substrates, system performance should be tested and confirmed on actual substrate.

Surface Preparation

Do not apply if the application surface temperature is below 45°F (7°C) or above 110°F (43°C), or if the surface temperature is within 5°F of the dew point. It is highly recommended that sound practices as set forth by SSPC or NACE be followed when preparing a substrate for painting. At a minimum the surface should be clean of all grease, dirt, oil, rust and foreign material that would be detrimental to proper adhesion and desired performance of the coating system being applied.
