Step 1: Surface Preparation
All wood projects require preparation sanding. If you skip this critical step, your finish may fail.
Raw wood
- Sand with 120-grit sandpaper followed by 220-grit.
- Remove dust.
Sealed Surface
- Scuff clean with a Scotch-Brite™ pad or maroon synthetic steel wool & 50:50 mix of denatured alcohol & water.
- Dry 1-2 hours.
- Sand lightly with 220-320-grit foam sanding sponge.
- 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
- Work in a well-ventilated area.
- Stir thoroughly to reincorporate solids that have settled to the bottom of the can before and throughout the application process.
- Test for color & adhesion over existing sealed surfaces.
- Thin as desired with distilled water; start with 5%, adding up to 10% by volume.
- 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.
- 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.
- 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.
- Dry 2+ hours between coats based on ideal conditions: 70°F/20°C; 50-70% humidity. Be sure to allow adequate dry time.
- Finish sand between coats with a fine-grade (220-320) foam sanding pad to improve smoothness and adhesion.
- 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.
