CAUTION: Do NOT use any type of clear topcoat over GF White Poly, as it may cause yellowing.
When working over raw wood, 2 coats of either Stain Blocker or White Undercoat MUST be applied before applying Enduro White Poly to prevent tannin bleed through and ensure a successful outcome. Both work very well but Stain Blocker will achieve a slightly brighter sustained white.
When working over an existing finish, 2 coats of Stain Blocker MUST be applied before applying Enduro White Poly to prevent tannin bleed through and ensure a successful outcome.
General Finishes Enduro White Poly Application Steps
- Watch product overview video here or comparison of GF paints and pigmented topcoats here.
- 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. California Residents: Adding more than 2% of GF Extender will make the product
snon-compliant per SCAQMD Regulations. GF assumes no liability for the improper use of these products.
Ready to spray from container. Apply up to 2 coats of primer, plus 2 coats of GF White Poly. Additional coats will not improve durability.If a faster build is desired over raw wood, use General Finishes Sanding Sealer for the first coat, followed by 2 coats of White Poly.
- Spray application: Before spraying, strain through a medium-mesh filter. Spray wet films at 3-5-mil thickness. Medium air cap. Compressed air: .040, HVLP: .043 -.051 or Airless: .1 -.15. Verify tip sizes with your equipment supplier. See our spray tip size recommendations here. Keep your gun at a 90° angle, 6-8" from the surface. On large, flat areas, use wet, even patterns 6-8" wide. For narrow surfaces, reduce the fan pattern to 2-3" wide to reduce overspray. Overlap each pass 25% to conceal lines. Wear a mask and work in a ventilated space. Read here for more information on spraying techniques.
- Face frames: Enduro professional products are engineered to be spray-only but can be successfully applied successfully to cabinet face frames, edges or drawer fronts with a small cabinet-specific 3/8" nap microfiber roller such as Whizz or AllPro brand. Larger areas may not level with a roller application. Add 10-20% Extender for improved results.
Dry time based on ideal conditions: 70°F/20°C; 50-70% humidity. Tack free 5-10 minutes. Ready to sand 30-45 minutes. Recoat in 1-2 hours. Be sure to allow adequate dry time. You can tell if a water-based finish is dry if it forms a powder when lightly sanded with a fine-grade (220-320) foam sanding pad. If in doubt, wait longer. Rushing the dry time can cause "blush," which is clouding in the finish due to moisture trapped between the layers. Increase dry time if:Finish sand between coats with a fine-grade (220-320) foam sanding pad to improve smoothness and adhesion.
- Humidity is over 80%
- 3+ coats are applied
- Thick coats are applied
- Applying over an existing sealed finish
- Applying over products from other brands
Layering General Finishes water- and oil-based products:To accelerate dry time in humid conditions, add General Finishes Accelerator and work in a space with good ventilation and air movement. If you decide to re-coat before the recommended time, test dryness.
- Water over oil: Let oil-based products dry 72+hr before applying water-based products
- Oil over water: Let water-based products dry 24+hr before applying oil-based products
- Remove dust with a vacuum, compressed air, an oil-free tack cloth or a water-dampened rag.
- A topcoat is not required.
Water-based finishes cure and harden for full use after 21 days in ideal conditions. Avoid placing heavy objects on surfaces that have not completely cured. Treat gently, and do not clean with commercial products during the curing period.
Warning: Do not use water-based products with Linseed Oils or Danish Oils.
