Dry Spray is a common problem that occurs in the accurate application of coatings.
What visual appearance does dry spray take?
Dry spray appears as a rough, mottled surface, similar to orange peel.
What probable causes are there for dry spray?
- The coating is losing too much solvent as it is propelled toward the surface by the spray gun
What suggested solutions can solve the problem?
- Move the spray gun closer to the surface; reduce the velocity of the spray, or increase the ratio of coating to air in the spray
- Change to a solvent that dries more slowly
Support programs, free testing facilities and application advice are often made available from coating manufacturers, helping prevent problems early in the process, saving time and money.
