It really does feel like a paint booth has a sixth sense for attracting dust right before you start spraying! The good news is that it's usually caused by a few common issues rather than bad luck.

Start by checking whether the booth and surrounding workspace have been cleaned properly before painting. Overtime dust collects, so if you spritz the tables and even vacuum the room it would really help. Also have a look through the booths to check the filters. If they are dirty, they will not catch any particles in the air Air flow--This is also very important. The paint booth should have excellent, balanced, and steady ventilation.If the fans are not working properly or if the air flow is even, fumes and overspray will swirl back onto the freshly painted surfaces. Never ever take any dusty materials like cardboard boxes, rags or dirty tools near the booth as they will release dust particles as you are working.Also, don't forget static. Some plastics and other materials may easily pick up dirt before the paint goes on.

Using appropriate anti-static cleaning products or tack cloths can help reduce this problem.

Finally, consider your preparation routine. Clean the workpiece thoroughly, wear lint-free clothing, and allow enough time for the booth's ventilation system to clear the air before spraying.
