How to Build a Homemade Paint Booth

Determine the dimensions needed for your project. The dimensions depend on what you are painting. For example, if you are only painting small craft objects, you only need a paint booth the size of a small closet. If you are painting a car, you need a paint booth the size of a small garage. Measure the average size of the objects you paint and add enough extra length in each direction for you to comfortably walk around the object. Make sure the paint booth is also tall enough to accommodate the project.

Build a square framework out of PVC pipes based on the determined dimensions. Cut lengths PVC to the determined dimensions using a chop saw or a hand saw. Cut lengths for the corners, the ceiling edges and the floor edges. Join the corners using PVC corner fittings. The ends of the PVC pipe are simply pushed tightly into the holes on the fittings to create a three-way corner. If your booth is larger, you may need center beams halfway down each side. Affix a center beam using a PVC T-shape fitting. In this case the horizontal pipes have to be cut in the middle so they can be inserted into the fitting. The horizontal pipe ends go into the holes at the top of the 'T' and the vertical pipes go into the holes at the base of the 'T.'

Affix plastic sheeting to all sides. Cut sections of plastic sheeting with scissors according the dimensions of the booth sides and ceiling. Line up the edges of each plastic section to the PVC pipes and tape them down with duct tape. Make sure the tape runs the entire length of the plastic edge so it is completely sealed.

Measure the dimensions of a box fan. Cut a square three inches smaller than the fan in all directions at the base of the booth. Cut an diagonal slit at the upper corners of the cut out square to create flaps. Fit the fan into the square and tape the flaps to the sides of the fan to seal it.

Cut a longer slit somewhere else in the plastic for a door way. Tape another section of plastic over the slit that is long enough to reach the ground. The plastic will drape over and cover the slit to keep the gap blocked.
