In most situations a primer is not necessary, even when painting rusty metal. 1 generous coat is often sufficient, but when recoats are necessary they must be applied within 4 hours or after 6 weeks (hammered finish) or 48 hours (smooth finish). Dries to touch in 30 minutes or less. Large areas should be rolled or sprayed. Covers approximately 18 to 20 sq ft per spray can. Ideally should be applied at temperatures between 60 deg. F. and 80 deg. F. For best results, clean brushes with Hammerite Brush Cleaner and Thinner. Smooth finishes are listed under Hammerite metal smooth finish.
