DIY Installing a Wall Access Panel |
Also see: |
You can buy a prefab access panel for a neat opening in drywall or plaster walls and ceilings for plumbing or electrical work. These panels install quickly and come in sizes from about 10 inches to about two feet or more. The dimensions for the panel opening will be included in the packaging. A drywall saw can be used to cut drywall and some plaster walls. To cut wood lath plaster and other thicker walls, use a reciprocating saw. | |
Mark a square on the wall the size of the panel. Determine where you want the top of the opening to be in the wall. Draw the top line using a level to keep the line straight. Measure from the top line and mark the point for the bottom line. Use the level to draw a straight line and then use a framing square to draw the lines along each side. | |
Use a drywall saw to cut along the line on the top and then down both sides. Don't cut the bottom line with a saw. | |
Use a drywall knife to score the drywall along the bottom line. Cut cleanly and then push in on the drywall to snap it along the scored line. | |
Cut through the remaining paper on the inside of the square to free the drywall cut–out and let it fall. You can leave it inside the wall or pull it out after it is free. | |
Remove the panel cover using a pen knife or screwdriver to pry at one of the slots. Apply a bead of latex caulk along the back of the rim. | |
Press the frame into the square hole, pushing it flat against the wall. Make sure the frame is straight and press firmly to spread the caulk and stick it to the wall. Let the caulk set for an hour or so. | |
Press the cover in place and test to be sure it functions using a pen knife of screwdriver to pop it open again. | |
