How to Build a Paint Booth With Wood
Using a spray system to paint is one of the best ways to give a project a professionally finished look. From small crafts to cars and trucks, painting at home will save money and give you more control of the painting process. However, spray systems can be messy and produce harmful fumes. Building a spray booth with wood is an excellent way to manage these issues. A spray booth can be built inside an existing structure, like a barn or garage, or erected outdoors.

1
Decide on a size for your booth by measuring the object you wish to paint. Remember to allow space for the painter and the spray equipment inside the booth. A booth large enough to paint a car should be at least 10-by-15 feet, and 8 feet tall.

Build a wooden frame using the 2-by-4 lumber. Space the uprights about 4 feet apart, and use cross braces along the top of the booth. Saw the wood to create overlapping corners, and nail all joints from both directions.

If your booth is large, create corner braces by cutting opposing 45-degree angles on short lengths of scrap 2-by-4. Insert these braces into the corners of the booth, and nail them in place.

4
Leave a large opening at one end of the booth to serve as an unobstructed entry and exit. If your booth needs additional support, set aside a 2-by-4 as tall as the other uprights to serve as a supplemental upright that can be slid into place temporarily while the booth is in use.

5
Drape the frame with transparent plastic drop cloths. Tape the plastic to the frame using duct tape, taping all seams.
-
6
Leave the plastic siding loose at the open end of the booth so that it can be rolled back to serve as an entryway. If your booth is in the path of wind, tape down this side just before painting.
-
7
In one corner of the booth, at ground level, position a box fan so that it will blow outward, away from the booth. Cut a hole in the plastic siding slightly smaller than the fan.
-
8
Insert the fan into the hole and seal the edges with duct tape. Make sure that the fan's power cord is on the outside of the booth and can reach an outlet.
-
9
On the opposite wall of the booth, cut a hole of a similar size. Cover this hole with a cotton bed sheet and tape it in place. This will serve as a filter for air drawn into the booth when the fan is turned on.

Tips & Warnings
Before turning on the fan, dampen the bed sheet filter with water in a spray bottle. This will prevent dust from entering the booth, where it could cause damage to wet paint. Wash or replace the sheet occasionally as it becomes visibly dirty.
When using your paint booth, be sure that the exhaust fumes are blown into a place away from people or animals.
