Pruett-Schaffer’s #67-12068 Gray-Green Enamel is a fast air drying, solvent based, urethane modified alkyd paint. It is designed as a high gloss, brush or spray applied finish coat for a variety of exterior or interior maintenance applications. It exhibits good abrasion and corrosion resistance, color fastness, and exterior durability.

For best results, metal substrates should be blasted to SSPC-SP-6 commercial blast, with a 1 mil blast profile, and primed with a good quality alkyd primer (such as Pruett-Schaffer #30-12620).

Unpainted concrete surfaces should be primed with this material thinned 5-10% with xylol, then recoated within 24 hours with full strength material. All previously painted concrete surfaces should be scraped or sanded to remove all loose coating and to scuff up the surface to provide better adhesion, then washed and allowed to dry completely.

Bare wood surfaces should be primed or coated twice with this paint. Existing coatings must be tightly adhering and deglossed by sanding for best adhesion.

In general, this coating is very tolerant of less than perfect surface preparation, so hand or power tool cleaning may be sufficient for many applications. At a minimum for acceptable performance, surfaces to be coated must be clean and dry, and free of oil/grease, loose rust/paint, weld spatter, burning slag, dust, and chalk. Feather all rough or sharp edges.

May be applied by brush, roller, or conventional airless or air-assisted spray equipment. Brushes should be of polyester or nylon construction. Rollers should have a nap thickness of ¹/₄ to ³/₈ inch. Use a .015-.020 inch spray tip size. Apply to 3-4 mils dry film thickness (6-8 mils wet) when no primer is used; or 2-3 mils dry film (4-6 mils wet) over primer.

intercoat adhesion may occur. Force drying ovens may be used, allow 30 minutes minimum for flashoff of solvent before heating.

Clean equipment with mineral spirits, xylol or toluol before the film dries.
