Quick knock-down spray booth with 20” fan for water-borne finishes. 6’ horizontal capacity.

Works great with my HVLP system.

Furniture, so the 60” width will come in handy.

I’m new to HVLP, so I’ll use this to learn.

Is that fan enough for HVLP over spray? Looks like something that will come in pretty handy.

Still not sure if the fan is enough, although Jeff Jewitt uses a similar one in his knock-down booth in his spray finishing book. I haven’t noticed any overspray around my shop, FWIW. Changing filters on a regular basis may be key.

It’s actually 72” width, I mistyped above.
I do have one fan on the outside of each side of the booth pointed out the garage door, so laminar flow, hopefully, outside the booth exhausting and overspray that escapes.

Do you close off the front after you spray while the finish cures to keep the fan from sucking dust across the piece?

zzzzdoc—This looks like a solution I have been in search of.

Where did the plastic sheeting come from? I had considered doing something akin to this with the ‘painter’s tarps’ you find in the paint department at the big box.

Great idea and convenient. The clear plastic lets light in besides protection.

Loose the filter. It’s on the wrong side of the booth anyway, it’s filtering the air leaving the booth. You should be filtering the air coming into the booth. It’s also slowing down the draw from inside the booth. Otherwise, I’ve sprayed in something like this most of my 25 year career.

The plastic sheeting is 6 mil sheeting from HD.

Outside of a two fan system, or an airtight booth, I can’t see an easy way to filter air coming into the booth. I do keep my Jet air filter going when I use my HVLP, which does help tremendously, at least according the the Dylos meter. No question the filter reduces airflow, but I also don’t want to destroy my driveway by spewing finish on it.

Working on modifying it, adding a much more powerful explosion-proof fan, and more filter area.

Stay tuned for more details.

I remember seeing this before and recently saw where someone made a homemade spray booth so I wanted to search for this.
Looks great.
My biggest question is about the “explosion proof fan”. Someone mentioned this sort of thing in the other post. Very curious about this.
