How to Attach an Access Panel in Drywall? A Step-by-Step Guide


Have you ever needed to access a particular facility area behind your construction project's drywall surface but wanted to avoid cutting a large hole and ruining the aesthetics? Installing an access panel is your practical solution, granting easy access without damaging enormous drywall sections.

This blog article will provide a detailed step-by-step guide to contractors, professional drywall installers, and DIYers with instructions to create an opening and correctly attach an access panel. From marking the wall to trimming it, we'll tackle each step clearly—aiming to empower those individuals to finish this handy project efficiently and successfully.

8 Tools to Prepare Before Drywall Installation Before we proceed with discussing the access panel application tutorial in drywalls, you must first prepare the basic tools below:

  • Tape Measure: It's a construction tool that will best accompany you in accurately marking and measuring the location and size of the access panel cutout.

  • Utility Knife: It's an important building component that will help you carefully cut the drywall along the pencil lines and trace the opening of the access panel.

  • Drywall Saw: Drywall trimming can turn messy. Thus, having a drywall saw is a must to aid you in cleanly cutting out the drywall piece inside your marked lines—helping you make neat, straight cuts.

  • Drywall Hammer: Preparing drywall is necessary as you'll use it to break out the cutout drywall piece and gently tap in the access panel frame.

  • Access Panel: You will install this functional and handy pre-made plastic or metal panel like BA-DW-5040 flush with drywall bead flange access panel into the cutout opening.

  • Drywall Screws: Depending on the access panel type you bought, you must prepare drywall screws to securely attach and mount the access panel frame into the wall opening. No worries, as they often come along with your product purchase.

  • Pencil: You'll need a tool that will help you mark the cutout opening lines on the drywall surface.

  • Safety Gear: It may look simple, but installing an access panel in your construction project's drywall surface can be dangerous. Hence, you must equip yourself with essential safety gear, like safety glasses, respirator masks, and gloves—to protect yourself while cutting into the drywall.

How to Properly Install an Access Panel in Drywalls


Attaching access panels to drywall surfaces is a straightforward process that contractors, professional drywall access panel installers, or even DIY enthusiasts can do. These panels are essential to grant technicians and maintenance personnel easy access to plumbing, electrical, or HVAC systems behind walls. Here's a detailed, step-by-step guide to help you with the installation:

Step 1. Mark Out the Opening: Bring out your tape measure and mark the access panel's dimensions onto the drywall where you aim to place the opening. Remember to consider the frame size so there is room for it to attach fully.

Step 2. Cut the Opening: With the help of a utility knife, you need to meticulously score along the tape measure traces and trim the drywall piece. Remember to remove any cutout debris.

Step 3. Attach the Frame: You can position the access panel's frame over the opening, guaranteeing it is level and lined up correctly. Afterward, you must drive drywall screws through the frame flanges and into the drywall edges every 6-8 inches to hold it tightly in place.

Step 4. Tape Joints: The next step involves the application of joint tape around the perimeter seam where the frame meets the drywall through a taping knife, which you'll use to press it firmly against the seam. It would also be best to ensure the tape is fully adhered.

Step 5. Mud Joints: The fifth involves spreading a thin, even layer of drywall joint compound over the tape using your taping knife. You can feather the mud about an inch past the tape onto the adjacent drywall and frame facades.

Step 6. Let It Dry: You need to give the first joint compound coat some time to dry thoroughly. It usually takes around 30 to 60 minutes, depending on different circumstances.

Step 7. Sand Joints: Lightly sand any flaws or textures with 120-grit sandpaper. Remember to wipe away the dust to enjoy its smooth and pristine appearance.

Step 8. Apply Second Mud Coat: For the second time around, apply a thicker joint compound coat over the sanded first coat with a taping knife. You need to also feather it out past the first coat.

Step 9. Let It Dry and Sand Again: Just repeat the drying and sanding process with 180-grit paper to achieve your desired slick finish.

Step 10. Install Panel: After perfecting the opening and panel installation, you can insert your access panel cover into the frame opening. Never skip the securing process to guarantee its tight protection. You can follow the manufacturer's instructions for adequately fastening the component.

Step 11. Inspect and Clean Up: You must thoroughly check the panel and the area for missed spots so you can apply the necessary touch-up as needed. Once done, you can start cleaning your equipment and your workspace.

Now, Enjoy Massive and Long-Term Benefits



Following the step-by-step process outlined above and taking proper safety precautions, contractors and DIYers can swiftly complete the installation process, ensure it functions well, and blend seamlessly into surrounding drywall surfaces. Whether the goal is to allow access for servicing systems or conceal unsightly wall elements, taking the time for a professional installation will pay off in ease of use and longevity of the access panels.
