I have my booth vented out the garage door. I don't have windows in my garage and it is made of concrete block. I have to lower the garage down till it touches the hose and holds it in place. I have a 30' hose that I can then move about 15' around the corner of the house so it doesn't come back in. However, the stink still overpowers my paint booth so their are fumes around me and in the garage.
I've been thinking about getting a very small plastic tool shed that I can put up (hide) next to the house that is just big enough for me to paint in (with spray booth). I'll put a portable A/C in it to cool it and reduce humidity before I start painting. That is about the only thing I can come up with unless I decant the clear or get a bottle of it and reduce my pressure considerably so the booth can better handle it.
