The HS9300 System Epoxy Primer is a two-component, low VOC polyamine converted epoxy primer. Designed as primers for clean, abrasive-blasted or slightly rusted steel, masonry or concrete for topcoating with 9400 System High Gloss Polyester Urethane or 9700 250 VOC Acrylic Polyester Urethane.

ALL SURFACES: (SSPC-SP-1) Remove all dirt, grease, oil, salt or other contaminants by washing surface with Krud Kutter® Original Cleaner Degreaser, commercial detergent or other suitable cleaner. Rinse thoroughly with fresh water and allow to fully dry. Thoroughly cured previous coatings or new metal surfaces which are very smooth may require scuff sanding to maximize adhesion. 

STEEL – SEVERE EXPOSURES: Abrasive blast to a minimum SSPC-SP-6 Commercial Grade (NACE 3). Two coats of primer must be used. 

STEEL – MODERATE EXPOSURES: Scrape and wire brush or power tool clean to remove loose rust, scale and deteriorated previous coatings. 

CONCRETE AND MASONRY SURFACES: After cleaning, repair surface defects and remove deteriorated previous coatings. Abrasive blast or acid etch smooth dense concrete using 108 Cleaning & Etching Solution followed by thoroughly rinsing with fresh water. Allow new concrete and masonry to cure at least 30 days before coating. Any concrete surface must be protected from moisture transmission from uncoated areas.

Mix the base component well before adding HS9303 Activator (included in kit). Continue to mix while adding activator. Allow a 30 minute induction period before using. The container is shortfilled to allow for addition of activator. Do not activate more material than can be used in an 8 hour period. Apply only when air and surface temperatures are between 60-100°F (16-38°C) and surface is at least 5° above dew point.
