DESCRIPTION AND USES
Rust-Oleum® Sierra Performance™ Acrylic Primer is a low VOC, low HAP, very low odor, adhesion promoting acrylic primer for smooth surfaces.
Sierra Acrylic Primer is suitable for concrete, masonry, nonferrous metal, galvanized steel, plastic, wallboard, wood, plaster, stucco, and previously coated surfaces. It can be used for both interior and exterior applications. Since this coating is very low odor during application, it is ideal for use in warehouses, schools, healthcare facilities, food service areas, office buildings, hotels or in any area where odors are an issue. For steel substrates use Sierra MetalMax™ DTM Acrylic Enamel.
Sierra Acrylic Primer is suitable for use in USDA regulated facilities provided it is topcoated with a finish that complies with the USDA FSIS regulatory sanitation performance standards for food establishment facilities.

PRODUCT APPLICATION
SURFACE PREPARATION
ALL SURFACES: Remove all dirt, grease, oil, salt and chemical contaminants by washing the surface with Krud Kutter® Original Cleaner Degreaser, commercial detergent or other suitable cleaner. Rinse thoroughly with fresh water and allow to fully dry. If any mold or mildew is present on the surface clean further with one quart of household bleach added to a gallon of water. Rinse with clean water. Severely mildewed areas should be cleaned with a chlorinated cleansing powder and thoroughly rinsed with water. All surfaces must be dry at time of application.
GALVANIZED STEEL: New galvanized steel should be solvent cleaned to remove all post galvanizing treatments such oil, grease, or wax. Old or existing galvanized steel should be thoroughly washed to remove all surface contaminates.
CONCRETE AND MASONRY: Hand or power tool clean to remove all loose or unsound concrete, masonry, or previous coating. Very dense, non-porous concrete should be acid etched or abrasive blasted to remove the laitance layer and create a surface profile. Allow new concrete to cure for 30 days before coating.
PREVIOUSLY COATED: Previously coated surfaces must be sound and in good condition. Smooth, hard, or glossy finishes should be scarified by sanding to create a surface profile. Sierra Acrylic Primer is compatible with most coatings, but a test patch is suggested.
APPLICATION
Mix thoroughly. Apply only when air and surface temperatures are between 50-100°F (10-38°C), the relative humidity is no greater than 85%, and surface is at least 5°F (3°C) above dew point. Dry times may be effected by extremely high or low relative humidity. Ensure fresh air entry during application and drying. Sierra Acrylic Primer is immediately sandable when dry.
TINTING
Sierra Acrylic Primer White can be tinted with Rust-Oleum 2030 Water-based Colorants or other high quality water-based or universal colorants, however these colorants will slightly increase VOC, but if used at the recommended levels, the VOC will not exceed 100 g/l. Use up to 2 oz. per gallon.
EQUIPMENT RECOMMENDATIONS
BRUSH: Use a good quality synthetic bristle brush.
ROLLER: Use a good quality 3/8" synthetic nap roller cover.

CAUTION: Protect surrounding surfaces from over spray. Over spray can be wet or dry depending on height of work, weather, environmental conditions and application equipment. Wet over spray can adhere to unwanted surfaces. Dry over spray may be removed by wiping or washing. Always clean dry over spray from hot surfaces before fusing occurs as surface temperatures can be higher than the air temperature.
THINNING
If needed thin with water. Do not exceed 4 fluid ounces per gallon.
CLEAN-UP
