How a temporary on-site spray booth works

What a temporary booth actually consists of

A framework of poles or a demountable pop-up structure lined with polythene or fire-retardant sheeting creates an enclosed space with controlled airflow, usually with a filtered extract at one end pulling overspray away from the drying item. Lighting is set up specifically for spraying, since standard room lighting rarely shows up thin patches or missed edges well enough.

• Sheeted or pop-up frame sized to the items being sprayed
• Filtered extraction pulling air and overspray away from the work
• Dedicated raking light to check film evenness while wet

Why filtered airflow matters more than people expect

Still air in an enclosed booth lets dust settle onto wet paint and lets solvent or water vapour build up, both of which affect the finish. A gentle, filtered airflow moving from clean to dirty across the booth keeps dust off the drying surface and clears vapour without disturbing the wet film with a direct draught.

Sequencing items through a limited space

Where several doors or panels need spraying and only one small booth is available, the sequence is planned around drying and recoat times so items move through in batches rather than one at a time, with a drying rack set up outside the spray zone to free the booth for the next item.

• Items batched by finish and colour to reduce gun cleaning
• A separate drying area kept dust-free outside the spray zone
• Recoat windows tracked so nothing is sprayed too early or too late

When a temporary booth is not the answer

Very large volumes of joinery, or items too big to fit any reasonable temporary structure, are usually better served by a proper workshop facility or a fully sheeted room spray. A temporary booth is the right answer for tens of items on a constrained site, not hundreds.
