Surface Preparation

  • Wood: Apply an appropriate primer according to the manufacturer's instructions, contact Blue River Coatings for compatibility. Once the primer is dried, sand with a fine grain sandpaper until smooth. Apply HPA Color Shield to the debris-free surface.
  • Steel: Apply an appropriate primer according to the manufacturer's instructions, contact Blue River Coatings for compatibility. Test a small area for coating-to-primer adhesion before full application of HPA Color Shield.
  • Aluminum: Apply an appropriate primer according to the manufacturer's instructions, contact Blue River Coatings for compatibility. Lightly abrade the surface, clean the surface with a mild detergent, rinse with distilled water, and dry.
  • Fiberglass: Lightly abrade the surface and remove debris. Wipe with acetone and let flash. Ensure surface is clean and dry before applying HPA Color Shield.
  • Concrete: Sweep the area to be coated, scrub the area with water and a push broom, and use a concrete cleaner to remove oil and grease. Rinse the area with water and use an etching additive. If cleaning/coating a vertical surface, work from the top of the substrate down. The substrate must be completely dry prior to HPA Color Shield application.

Application Methods

Stir contents before use. Never shake or mix under high agitation, for all substrates, HPA Color Shield can be sprayed, brushed or rolled.
  • Spraying: Reduce to 20-25 seconds, Zahn #2. Apply a medium wet coat over the surface. For best results, apply with a spray gun with the tip size of 1.2-1.8 mm, air pressure should be 15-25 psi for HVLP and 25-40 psi for conventional spray guns. Atomization pressure depends on viscosity.
  • Brushing: Reduce 30-38 seconds, Zahn #2.
  • Coats Required:
    • Wood: 1 - 2 coats
    • Steel: 1 coat
    • Aluminum: 1 coat
    • Fiberglass: 1 coat
