Application Conditions: Recommended 70°F and 50% humidity, out of direct sunlight. Variations in conditions and application technique can significantly affect dry times and coverage. Use GF Accelerator in cool or humid conditions. Use GF Extender in warm or dry conditions.
Surface Prep: Always ensure the surface is clean of contaminants and dust. Sanding any surface too smoothly can reduce adhesion and create application issues like orange peel.
Raw Wood: Sand with no finer than 220 grit. Ensure any freshly stained surface has dried thoroughly and completely.
Pre‐finished Wood: Clean using 50/50 mix of denatured alcohol and water with maroon non‐woven pad. Sand with fine (220‐320) foam sanding pad or maroon non‐woven pad.
Other Substrates: Can be used with proper priming and/or painting. Always test first.
Sanding Between Coats: Using fine (220‐320) foam sanding pad or gray non‐woven pad.
