EPOXY FLOOR PRIMER

DESCRIPTION OF PRODUCT

#80-1 Epoxy Floor Primer is a high performance, feldspar filled, two component, epoxy phenalkamine coating. It provides a suitable base coat for many types of epoxy floor systems. It can be applied over concrete, steel, and repair compounds. This primer has no induction time, will cure well even at low temperatures and in high humidity, and is very easy to use. It is recommended for areas exposed to acids, alkalies, oils, fuels, salt, and solvents. This product is designed for use by experienced professional applicators only.

PACKAGING

This coating is packaged and labeled as 80-1-A Epoxy Component and 80-B Hardener Component. Each component is supplied in 5-gallon pails filled to 2½ gallons each. The shipping containers may be used for mixing on the job site.

MIXING INSTRUCTIONS

Allow the components to reach room temperature before using, best results are obtained when applied at 70-80 °F. Completely pour a pail of B Component into a pail of A component and mix well with a low speed paddle mixer. Avoid entraining air into the coating. Then pour the mixed coating into the B Component pail just emptied and mix again (boxing).

SURFACE PREPARATION

Remove heavy accumulations of grease and oil, if present, with solvent or by powerwashing with a water/detergent solution. Sandblast or shot blast the area to be primed to remove all existing coatings and contaminants that may have penetrated the surface. Vacuum to remove sand and debris. Acid etching is not recommended as a preparation technique because complete rinsing is usually not practical.

Cracks wider than ¹/₈ inch, spalled, or damaged concrete should be repaired with an epoxy surfacing compound equivalent to Pruett-Schaffer's 12-Series Epoxy Floor Surfacer before priming. Follow applicable directions for resurfacing.

Use only freshly opened shipping containers for mixing; mixing epoxy in previously used containers will accelerate the cure of the system dramatically. Always clean the mixer blades between each use.

APPLICATION METHOD

Apply the mixed coating to the floor with a ³/₃₂ inch notched squeegee for thicker films over rough surfaces (about 20 mils of primer), or use a flat squeegee for thinner films (5-10 mils of primer). Follow the application with a short napped roller (¼ inch or less) to smooth out the coating. Apply in a cross-coat pattern to assure complete wetting of the substrate. Areas adjacent to obstructions may be coated with a brush or roller.

THINNING AND CLEANUP

Thin with xylol to a maximum of 2 quarts per mixed 5-gallon pail for cold weather application. Clean equipment with xylol or a xylol/MEK mixture.

CURE AND RECOAT TIME

This coating cures tack free in 8 hours at 70 °F. Recoat within 36 hours or reduced intercoat adhesion may occur. Longer curing times will be necessary when air or substrate temperatures fall below 50 °F. Ultimate cure and chemical resistance in 7-10 days at 70 °F.
