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. If the primer is going to be applied over a stained area, try to remove as much of the stain as possible by washing, sanding, or scraping. All surfaces must be dry at time of application.
STEEL: Hand tool (SSPC-SP-2) or power tool (SSPC-SP-3) clean to remove loose rust, mill scale, and deteriorated previous coatings. Abrasive blasting to a minimum Commercial Grade (SSPC-SP-6, NACE 3) with a 1-2 mil (25-50 μ) surface profile is recommended for optimal performance. Abrasive blast cleaned steel requires two coats.
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: 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. If some of the previous coating has been removed, featheredge the terminal edge by sanding to form a smooth transition to the substrate.
Universal Acrylic Primer is compatible with most coatings, but a test patch is suggested.

APPLICATION

Apply only when air, material, and surface temperatures are between 50-90ºF (10-32ºC) and the surface temperature is at least 5ºF (3ºC) above the dew point. The relative humidity should not be greater than 85%.
Mix thoroughly to ensure any settled pigment is re-dispersed before using. In most cases only one coat is necessary to prime most surfaces. If excessive absorption occurs over very porous substrates a second coat may be necessary.
Spot priming is recommended only under high-hiding topcoat paints. For best results, prime entire surface before painting. Apply with a natural or synthetic bristle brush, roller, pad or sprayer.
Follow manufacturer’s instructions when using spray equipment. Airless spraying, use a .017″ tip at 2000 to 2500 psi.
THINNING
Do not thin.
CLEAN-UP
Clean up with soap and water and dispose of all waste material in a proper manner and in accordance with local waste regulations. Consult with local environmental regulations for appropriate method of disposal and/or recycling of paint and empty container.
