Tips

  • Work in a well-ventilated area when staining and applying resin.
  • Allow ample drying time between stain coats.
  • Use a heat gun or lighter to remove bubbles from the resin (optional).
  • Avoid touching the freshly cured resin to prevent fingerprints.
  • Using permanent vinyl and sealing with resin ensures maximum weatherproofing.

Common Mistakes to Avoid

1. Insufficient Resin Coating

Reason: Not applying enough resin layers to fully encapsulate the vinyl decal and protect the wood, leaving the edges and surface vulnerable to the elements.
Solution: Apply multiple thin layers of resin, allowing each to cure completely before applying the next, ensuring complete coverage.

2. Using Contaminated Resin or Surfaces

Reason: Dust, debris, or moisture on the wood or in the resin can create air bubbles, imperfections, and weaken the seal, compromising the weatherproofing.
Solution: Ensure both the wood and resin are clean, dry, and dust-free before starting the process.
