Stats: Dries to the touch in 30 minutes, tack free in 1 hour, recoatable in 4 hours, dries hard in 8 hours. Apply by brush, roller or spray. Coverage is approximately 250-300 square feet per gallon @ 2 mils dry film thickness.
Recommended preparation: For best results remove old marine coating, loose scale, grease, oil and contaminates. Sand, grind, bead blast or power-wash prior to the application of any cleaner or primer. Where rust is evident use SM-5679 Phos-Pro Rust Converting Cleaner. All surfaces must be thoroughly clean and dry before the application of any marine primer, boat paint or antifouling bottom paint.
Application: Recommend applying a minimum of 2 coats. Apply by brush, roller or airless sprayer. For conventional sprayers thin if necessary with SM-620 Thinner or MEK.

Epoxy Primer should be allowed to dry a minimum of two to three hours before recoating with subsequent primers or marine coatings. It should be applied to a dry film thickness between 0.3-0.4 mil. For non-marine equipment or on iron or steel surfaces it should be applied to 0.6-0.8 mil dry film. NOTE: This epoxy primer is designed for application over surface-treated metal or pretreatment coatings (SeeSM-117 Pre-Treatment Wash Primer). If used for dip or flow-coat application, the product suitability should be determined by the user.
