DESCRIPTION AND USES
Rust-Oleum Professional Primer is a premium, all purpose, high-performance, water-base primer for interior and exterior residential, commercial, and industrial applications. It combines fast-dry convenience with outstanding adhesion to glossy surfaces and dependable stain blocking power. May be used under and over any oil or latex architectural paint. Dried film is mold and mildew resistant and inhibits rust. Apply to interior and exterior walls, ceilings, doors, trim, fascia, soffits, foundations, railings, and related paintable surfaces. It resists high pH surfaces (up to 12.5) and seals most porous surfaces. Professional Primer traps most stains in the primer film including graffiti, grease, rust, cedar and redwood tannin, creosote, and asphalt stains.

PRODUCT APPLICATION
SURFACE PREPARATION
Surfaces should be clean, dry, sound, and free of dust, dirt, excessive chalky material, grime, grease, oil, wax, mildew, wallpaper, adhesive or any contamination that may interfere with adhesion. If unsure of cleanliness, always wash surface with an appropriate ammoniated cleaning solution or solvent (do not use TSP as a cleaner). Remove any peeling and/or unsound coatings. Scuff sand bare aluminum. Sand any remaining paint film edges smooth with the surface. Lightly sand exposed exterior wood with 80 to 100 grit sandpaper to remove loose or weathered wood fibers and mill glaze.
PRIMING
Use on all types of bare or painted surfaces including wood, drywall, cured plaster, concrete, stucco and masonry, glossy enamels, hardboard, glass, tile, aluminum, vinyl, steel, galvanized metal, and PVC. It has excellent adhesion to dense glossy surfaces such as enamel paints and varnishes, paneling, laminates, and ceramic tile without sanding or deglossing.
SEALING
Contains a unique resin that seals porous surfaces and provides a smooth and even finish to extend the coverage of topcoats and provide uniform and consistent sheen. It helps bind chalky surfaces and is suitable for use on moderately chalked aluminum or previously painted siding and trim.
APPLICATION
Shake or stir well and apply using brush, roller, or sprayer (follow spray equipment manufacturer’s instructions; for airless spraying use .017 tip at 2000 - 2500 P.S.I.). If thinning is required add no more than 10 oz. (295 ml) of clean water per gallon and apply a second coat of primer. Apply between 35°F and 90°F (2°C and 32°C), and when the relative humidity is below 85%.
DRY TIME
Dries to the touch in about 30 minutes; can be top coated in 1 hour. Full adhesion and hardness develops in 7 days.
COVERAGE
Approximately 400–450 sq. ft. (37–42m2 ) per gallon. Coverage may vary with application method and surface porosity.
CLEAN UP
Clean up spills and paint drips with warm water and liquid detergent. Wipe up splatters before they dry. Follow manufacturer’s directions to clean spray equipment. Dispose of unused or unwanted product in accordance with local laws regulating solvent-based coatings.
LIMITATIONS
Not recommended for application to floors or decks or to surfaces subject to immersion or prolonged contact with water.
