Applying the Spray Finish for Wood

This section provides step-by-step instructions on how to apply the spray finish.

• Setting Up Your Spray Area:
  • Ensuring adequate ventilation.
  • Using a spray booth or drop cloths to protect surrounding areas.
  • Proper lighting for visibility.
• Preparing the Finish:
  • Thinning the finish (if necessary) according to the manufacturer’s instructions.
  • Straining the finish to remove any impurities.
  • Testing the finish on a scrap piece of wood.
• Spraying Technique:
  • Holding the sprayer at a consistent distance from the surface.
  • Using smooth, overlapping strokes.
  • Avoiding runs and drips.
  • Applying thin coats to build up the finish gradually.
• Drying and Curing:
  • Allowing sufficient drying time between coats.
  • Following the manufacturer’s instructions for drying and curing times.
  • Maintaining the proper temperature and humidity.
• Sanding Between Coats (Optional):
  • Using fine-grit sandpaper (e.g., 320 grit) to smooth out any imperfections.
  • Cleaning the surface thoroughly after sanding.

Troubleshooting Common Problems with Spray Finish for Wood

This section addresses common issues that can arise during the spray finishing process.

• Runs and Drips:
  • Causes: Applying too much finish, holding the sprayer too close to the surface, improper thinning.
  • Solutions: Sanding down the runs and drips, adjusting the sprayer settings, applying thinner coats.
• Orange Peel:
  • Causes: Finish drying too quickly, improper thinning, incorrect sprayer settings.
  • Solutions: Adjusting the thinning ratio, using a retarder, adjusting the sprayer settings.
• Bubbles:
  • Causes: Agitating the finish too vigorously, applying the finish too quickly, high humidity.
  • Solutions: Allowing the bubbles to dissipate before spraying, applying thinner coats, using a defoamer.
• Fish Eyes:
  • Causes: Contamination on the surface (e.g., oil, silicone).
  • Solutions: Thoroughly cleaning the surface with a degreaser, using a fish eye eliminator additive.

Maintenance and Care of Sprayed Wood Finishes

• Regular Cleaning: Using a soft cloth and mild soap to remove dust and grime.
• Avoiding Harsh Chemicals: Avoiding cleaners that contain harsh chemicals or abrasives.
• Repairing Scratches and Dents: Using touch-up pens or finish repair kits.
