A single-car garage is typically 9 to 10 feet (2. 7 to 3. 0 m) across, as an example, though they can be as big as 12 or 14 feet (3. 7 or 4. 3 m) across.

For instance, for the example project, you’ll need 9 10 feet (3. 0 m) sections of PVC pipe with a diameter of 1. 25 inches (3. 2 cm). This diameter is sturdy enough for most projects. PVC pipe is typically sold in sections that are 10 feet (3. 0 m) long.

For the example design, the sections you need are as follows: 3 8-foot (2. 43 m) sections 1 5-foot, 11 3/4-inch (1. 82 m) section 2 4-foot (1. 22 m) sections 2 3-foot, 11 7/8-inch (1. 22) sections 6 3-foot (0. 91 m) sections 2 2-foot, 7 3/4-inch (0. 806 m) sections 2 26 3/8-inch (0. 67 m) sections 2 20-inch (0. 51 m) sections 8 2 1/2-inch (6. 35 cm) sections

To clean up the ends of the pipe, rub them down with a sanding block. A simple hacksaw can also cut through PVC pipe. [4] X Research source

Check the 3-foot (0. 91 m) pipes and choose the ones that have most even ends. These will form the 4 posts at the corners that touch the floor. Lay out 2 more in the front on each side to form the top of these posts, then the 2 2-foot, 7 3/4-inch (0. 806 m) sections in the back for the top of these posts. The 3 8-foot (2. 43 m) sections go along the top horizontally in front and back and along the middle of the wall in back, while the 5-foot, 11 3/4-inch (1. 82 m) section goes vertically in the middle On the sides, the 4-foot (1. 22 m) sections form the middle horizontal poles, while the 26 3/8-inch (0. 67 m) will make the front half the horizontal section at the top and the 2 20-inch (0. 51 m) will make the back part of this section.

Ask for help with assembly if possible!

Do the same with the other side.

Don’t fully secure these joints until all the poles are in place.

If you’re having trouble with tape sticking properly, place the tape over the plastic and pole. Then, poke a hole through the plastic and tape on the inner side of the pole. Run a zip tie through the hole around the pole, tape, and plastic. Secure the zip tie to help hold the plastic in place.

You should have cut a large square out of the corner of the plastic on each side. Save these for the front.

Leave the opening between the 2 sheets in the front, except seal it a little at the top and bottom. When you get in the booth to paint, close this seam tightly with clamps. If the plastic doesn’t cover the front, you may need to get another sheet of plastic to cover the front.

If the cloth doesn’t fit right or it doesn’t line-up under the paint booth’s legs, step back to inspect the legs. Each leg should be near-perpendicular to the ground. Adjust as needed.

If necessary because of limited space, place the structure so that it is approximately 1 inch (2. 5 cm) from the middle PVC pipe. This will place the legs of the ladder inside the booth, but they will be covered by plastic.

You can also do the opposite if you prefer. That is, you can tape a filter into the side of the booth instead of the back of the fan. Then, just face the fan toward the filter.

When using the paint booth, always run the fan.

It may be helpful to add the new filter with a different color duct tape each time so you know which tape to remove or cut without touching the wrong tape.
