General Finishes Enduro Black Poly is an acrylic/urethane pigmented topcoat that exceed the durability of solvent lacquers and is on par with most solvent-based bi-component conversion varnishes for a cabinet-quality finish. It excels over wood or MDF and may be used in occupied homes, where solvent lacquer fumes are undesirable.

Enduro Black Pigmented Poly is a professional spray only, high-solids, pigmented water-based coating ideal for cabinets and millwork.

Directions for use

Step 1: Surface Preparation

All wood projects require preparation sanding. If you skip this critical step, your finish may fail.

Raw wood

  1. Sand with 120-grit sandpaper followed by 220-grit.
  2. Remove dust.

Sealed Surface

  1. Scuff clean with a Scotch-Brite™ pad or maroon synthetic steel wool & 50:50 mix of denatured alcohol & water.
  2. Dry 1-2 hours.
  3. Sand lightly with 220-320-grit foam sanding sponge.
  4. Remove Dust

Step 2: Priming

Raw Wood & Sealed Surface

GF Black Poly covers great on its own or can be applied over a primed surface.
Prime with GF Lamp Black Milk Paint to block grain or cover existing color.

Prime with GF Sanding Sealer for a smooth surface and to fill in voids.

Step 3: How to apply General Finishes Enduro Black Poly

General Finishes Enduro Black Poly Application Steps for Raw Wood & Sealed Surfaces

  1. Work in a well-ventilated area.
  2. Stir thoroughly to reincorporate solids that have settled to the bottom of the can before and throughout the application process.
  3. Test for color & adhesion over existing sealed surfaces.
  4. Thin as desired with distilled water; start with 5%, adding up to 10% by volume.
  5. Increase open time, if needed, with 10-15% General Finishes Extender if allowed by local regulations. GF Extender will improve flow and leveling and increase open time, which is helpful in dry climates.
  6. Ready to spray from container. Apply up to 2 coats of primer, plus 2 coats of GF Enduro Black Poly. Wear NIOSH-approved respiratory & eye protection.
  7. If a faster build is desired over raw wood, use General Finishes Sanding Sealer for the first coat, followed by 2 coats of Black Poly.
  8. Dry 2+ hours between coats based on ideal conditions: 70°F/20°C; 50-70% humidity. Be sure to allow adequate dry time.
  9. Finish sand between coats with a fine-grade (220-320) foam sanding pad to improve smoothness and adhesion.
  10. Remove dust with a vacuum, compressed air, an oil-free tack cloth or a water-dampened rag.

Warning: Do not use water-based products with Linseed Oils or Danish Oils.
