Spray finishing issues like dry spray can affect anyone—from beginners to seasoned professionals. This problem often occurs when you're working in a rush or using a new product, tool, or technique for the first time.
Why does Dry Spray happen?
Dry spray appears as a rough, powdery, or grainy texture—a sign that the coating dried too quickly, before it had a chance to properly bond with the surface. Here are the most common causes:
- Coats that are too thin: insufficient material prevents proper flow and leveling.
- Spraying from too far away: the finish dries mid-air before reaching the surface.
- Overspray: excessive mist in the air settles dry on the surface.
How can you fix Dry Spray?
- Lightly sand the affected area to smooth out the rough texture. Use fine-grit sandpaper and proceed carefully to avoid cutting through to the base coat or bare wood.
- Then, reapply the finish in a more controlled and even coat.
How can you prevent Dry Spray?
- Adjust your spray gun settings based on the product being used to ensure proper atomization.
- Maintain the correct spray distance—usually 6 to 8 inches from the surface, or as specified by the manufacturer.
- Control your spray speed to ensure even coverage.
- Avoid spraying in hot, dry, or windy conditions, which can cause the product to dry too quickly in the air.
