For coating primed or intermediate-coated surfaces; the surface shall be kept clean, dry and free from grease. Compatible previous coats: epoxy ester, epoxy, polyurethane and similar primers or intermediate coats.
Mix in the specified ratio for immediate use, and use within the pot life. After mixing and stirring thoroughly, allow to stand for 5–15 minutes before application. The curing agent reacts readily with moisture; keep containers tightly closed during storage and use. Humid weather during application affects the gloss and appearance of the film.
