For spray painting I added a small room in the garage. To control the overspray I have built a metal box which has a furnace filter on one side and 4 inch vent on the other side. The vent hose is connected to a dust collection system. Actually it is just the motor and fan. The system does a good job of eliminating the overspray both inside the room and outside. Because of the hassle of painting, I generally wait until I have a bunch of things to paint. The ladder is useful as a drying rack. For the final painting I generally use One Shot Paint. It is an oil based paint that I apply using a paint brush. Because of it slow drying time, painting seems to take forever. So my living room is a mess while I paint.
