Combination Blast and Paint Booths for Wisconsin Large Fabrications
Moving very large fabrications between a blast room and a paint booth takes crane time and floor space. Some Wisconsin fabricators handling marine sections, energy equipment and heavy weldments use a combination booth instead: one enclosure that blasts, then cleans up and paints. It saves a move but asks a lot of the air system and cleanup routine.

Blasting needs dust collection and media recovery; painting needs clean, controlled air. A combination booth switches between dust collection and paint exhaust modes, with separate filtration for each. The switchover includes cleanup to remove media and dust before painting starts.
- Dust collector for blast mode
- Paint exhaust filters for spray mode
- Mode switching through dampers and controls
Media Recovery Floors
Blast media is recovered through floor systems such as sweep-in hoppers or full recovery floors. Those floors must also work during painting without trapping dust. The choice affects floor construction and maintenance.
Cleanup Between Blast and Paint
Thorough cleanup between processes is the key to good paint results in a combination booth. Air washdown, floor cleaning and filter checks before spraying prevent media and dust in the finish.
When Separate Rooms Make More Sense
High-volume operations often justify separate blast and paint rooms so both can run at once. Combination booths suit lower volume or very large parts where moving them is costly.
Planning a booth or oven project in Wisconsin
Crews mobilize from Houston; Wisconsin is roughly 1,000 miles away, so equipment, panels and tooling are staged and shipped ahead of the install crew.
Manufacturing in Wisconsin is concentrated around Milwaukee, Madison, Green Bay, and Appleton. The sectors most likely to be specifying spray booths, blast rooms, powder systems and cure ovens there include heavy machinery and engines, paper products, food processing equipment, and metal fabrication.
Cold winters mean make-up air heaters are sized for sub-freezing intake, and booth or oven placement has to account for frost lines, snow loads on roof penetrations and winter slab work.
Frequently asked questions
Can one booth handle blasting and painting?
Yes, with separate air systems for each mode and thorough cleanup between.
How is blast media recovered?
Through floor recovery systems or sweep-in hoppers built into the booth floor.
What causes dirt in paint after blasting?
Incomplete cleanup of media and dust before spraying.
When are separate rooms better?
When volume is high enough that blasting and painting need to run at the same time.
