How to Build a Home Paint Booth - Page 2

For the output I ran 3 more fans with foam paint arresters. the output fans were not as powerful as the intake fans so I had a good amount of positive pressure. I may change out one of the output fans and install another of these box fans. I find when painting clear coat the fans can't keep up sucking out the dust. Its not a huge problem but I do see some fog in the booth which I would rather not have.

I didn't have a fresh air system, however had a fairly powerful compressor so I bought this SAS pure air 2000 filter, and a paint hood (about $260) The filter connects to the compressor and really does a great job of filtering air before it goes into the hood. I run my hood with 3 psi of Air while spraying and have zero smell of paint in the hood. The paint gun connects to the pipe on the bottom, this is nice because I avoid having two pipes in the booth stirring up dust, and helps prevent hose drag onto fresh paint. The system has worked well except that the gun air hose was defective and had to be replaced.

This SAS paint hood was about $60. It has disposable lenses covers and is quick and easy to get on and off. It is much better in my opinion than a mask. No straps to get out of whack. The hose comes off the back so it is out of the way of the paint.

Since I was running positive pressure it wasn't important that I had a perfectly air tight booth. The door was just cardboard and duct tape with velcro to hold it closed. Some small cracks were around the edges but weren't enough to let paint out of the booth in quantity.

I needed to have access to the compressor controls and filters etc., so made a door in the wall. I usually start the painting day off by cleaning out the water traps and filters!

Here the exhaust fans are lined up. I couldn't figure out a way to filter the center fan. Its a small fan and I'll probably replace it with another filtered box fan soon.

A few of the tools of the trade. I am using a Devilbiss Finishline II HVLP gun. Has been good for me. I find it is a little tricky with the PPG 2055 clear but I can manage it with fine tuning and technique. The spray bottle in the middle is used to spray an anti static mix on the booth, floor, and suit. Its 50/50 isopropyl alcohol and water. Plenty of paint filters and mixing cups, my fresh air setup, and the paint. The gallon can in the foreground is final wipe grease and wax remover. even have a timer for making sure I don't shoot before the flash times are done.

Here is the booth ready to go. I love those 1 mil plastic drop cloths They save me countless hours and worry with stray paint dust. Its time to mask up, clean up and get to the painting.
