After reading numerous posts from members, I built a multi purpose room on my existing shop. I am a firm believer a paint booth should be dedicated to paint only, but also had to face the reality that a dedicated room for paint only was just not in my reach. Consequently, I will be doing body work and paint in the same room, which under perfect conditions, should be avoided. I built this addittion with the idea that it should be easy to clean between body work and paint. I am a hobby restoration and have a Ford F-100s I am restoring. My air line is piped from the original shop with 1" copper for a run of about 40 feet where it drops into a filtering system. From there, the pipe is reduced to 1/2 copper where it returns to the paint room for the final filter. I use all high flow air fittings from Len to supply the paint gun. The lights are protected with 1/4" glass that drop down (hinged) for servicing when needed. Each piece of glass is protected around the edges with a piece of aluminum U channel. When the lens are in the closed position, they are sealed with a chemical resistant closed cell foam. Eight lights with 8 bulbs each are controlled by switches outside the room, one switch turns on the middle two bulbs of each fixture and another switch turns on the remaining four bulbs of each fixture. A third switch outside the booth controls all outlets in the booth so I can kill the outlets when I am spraying. I use two variable speed Jenny Fans with explosion proof baldor motors and switches. The fans are controlled by switches inside the booth. The exhaust air (not completed yet) opposite the fans is for outside air when tempretures permit painting (70 degrees or above). I have two filters in the side wall which pull air from the original shop when tempretures are below 70 degrees and the projects are small. The fans are enclosed with filters to catch contaminants on the way out of the booth. My breathing air is piped thru the wall with a hobby aire system recommended by Len. I use a full over the head hobby air mask while I am painting. I have used the booth and so far has worked well for small projects. Before I paint I blow out the room with an air hose followed by wetting the floor. I learned from Len one of the most important things to consider is light. With my present set up, I have no problem chasing the light in the upper part of the vehicle, but I need more light on the rocker panels. I am currently working on including photos to this post.
