Treat all surface defects caused by welding and processing, and grind sharp edges smooth. Blast clean to Sa 2.5 per ISO 8501:2007, or hand or power tool clean to St 3. Keep clean and dry.
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.
