Installing a Plywood Ceiling in the Garage Installing a Plywood Ceiling in the Garage

What You'll Need
4 by 8 foot sheets of plywood (1/2 inch thick)
Tape measure
Circular saw
Power screwdriver
Wood screws
Safety glasses

Adding a plywood ceiling to your garage can make the space more appealing. It’s a good project to undertake, especially if you plan on using the garage for more than just storing the car. It’s not difficult, but it’s not a job you can do on your own. You also need to have joists of sufficient sizes to hold the plywood securely. Follow these easy steps to install your plywood ceiling.

Step 1 - Measuring

Start by measuring the length and width of your garage. Doing so will give you a rough guide as to how many sheets of plywood you’ll need to buy. Select sheets that are straight. Disregard any warped pieces.

Ascend the stepladder and measure the distance between the joists, working from center to center. When you’re attaching plywood to make the ceiling, both ends of the plywood will need to be screwed to the joists. You will need to cut the sheets accordingly to make a plywood ceiling. Measure your plywood so that one edge fits on the joist above the garage door and extends to the furthest possible joist without running beyond the center of it. Mark the plywood to the correct size.

Step 2 - Cutting

Cut the plywood sheet to the correct size using your circular saw. It’s advisable to complete the cutting and hanging one piece at a time rather than cutting everything first. Doing so no only allows you to make adjustments as you go, but it also lets you grant allowances for any mistakes made while measuring for your plywood ceiling.

Step 3 - Hanging Plywood

The difficult part of installing a plywood ceiling is hanging the plywood. For this task, you need help. Ideally, it will take 2 stepladders and 2 people using screwdrivers simultaneously because of the size of the plywood.

Both people should hold one end of the plywood each as they climb up the stepladders. Push the plywood sheet into position so it’s exactly where you want it and make sure the far end is centered on the joist. Have your helper hold the plywood in position and use your power screwdriver to put in 2 screws that will initially secure the plywood. Hold the plywood while your helper does the same thing at the other end.

This step will secure the plywood so that you’ll both be able to put in more screws at each end. Screws should be spaced 6-inches apart. Once you’ve put the screws in at each end, add screws to secure the plywood to all the joists in between.

Step 4 - Completing the Ceiling

Continue to cut and install more plywood sheets. As you reach the edges, you’ll probably need to cut smaller pieces. Make sure the plywood is attached to the joists at both end. Screwing down the plywood to the joists will prevent your plywood ceiling from sagging.
