Swing a bat and miss? Time to learn how to repair drywall using a metal patch.

Learning how to repair a hole in drywall might seem daunting, especially when you are staring into a dark abyss that is your wall. However, metal patches make the repair process nice and simple. Bauen does provide a more advanced method for repairing holes in drywall which uses a drywall patch. Below we will breakdown the differences.

  • Medium – The medium method is great for holes that are 1-5″ wide and are in an area that you DO want to hang wall decor. You will be using a metal patching screen and setting compound – which dries rock hard. This method is much sturdier than the first and can support the weight of heavy items. This method tends to leave a visible raised area on the surface because of the thickness of metal patch. If you want a flat surface, look into the advance method below.
  • Advanced – The advanced method can be used for any size hole. It involves replacing the missing drywall with a new piece. You will then apply drywall tape and setting compound that is then sanded down to create a smooth surface. This method leaves you with the flattest surface out of all the patching options. Why? The patching tape is thin compared to the metal patch.

DIY or Hire?

You might be wondering if you should DIY or hire a professional. Bauen thinks this is a project you can handle on your own.

Assess your wall prior to starting.

1. How big is the hole in your drywall?
Measure the size of the hole in the drywall prior to purchasing your products. You want to make sure the metal patch covers the area!

Protection is key.

1. Protect Yourself. We recommend wearing a N-95 or P=sanding respirator to protect yourself from the sanding dust particles. Even though you don’t see them, the dust is in the air. You can also wear gloves and goggles.

2. Protect your Room. Move any furniture away from the hole. Place drop cloths on the floor and tape it to the baseboard using a quality painter’s specific tape. This will ensure no dust finds its way into your flooring.

1. Apply the Screen. Remove the sticker cover that is on the backside of the metal screen. Apply the sticky side of the metal screen over the hole. The sticky side will help adhere the screen to the surrounding drywall.

2. Mix the Compound. Pour your 90 min setting compound powder in a plastic container and add small amounts of water to the powder and mix with your putty knife. The goal is to make a cake frosting consistency. A good test is to put compound on your putty knife and turn it upside. If the compound stays on the knife, then you have a perfectly mixed compound. FYI – mixed setting compound cannot be saved for a later date, so make just enough to use in this pass.

3. Apply the Compound. Quickly apply the compound to the metal screen. It is a race against time once the compound mixes with water. Apply the compound liberally and make sure to cover at least 1” around all edges of the metal screen. This will help you create a smooth transition when sanding.

4. Clean. You will want to clean your putty knife and plastic container as soon as you complete the application process. It is much easier to clean your tools when the compound is wet. Use slightly damp paper towels to remove excess compound on your tools. Give a final rinse with water after excess is removed. You don’t want to send chunks of compound down your drain.

5. Dry Time. Allow the compound to fully dry. You will know its dry when the compound lightens in color. Even though the compound has a set time such as 45 minutes or 90 minutes, it can take longer to dry when thicker layers of compound are applied. The temperature of the room can also affect the dry time. The more hot and humid it is, the longer the drying will take.

6. Second Coat. Setting compound can shrink when drying. Apply a second coat if you can still see the metal screen. Allow the compound to fully dry before sanding.

7. Sand. Use your sanding pads to sand down the setting compound. We recommend starting with your medium sanding pad to cut through the top layers. This will greatly expedite your sanding process. Finally, move onto your fine sanding pad, followed by your extra fine sanding pad. Continuously wipe away the sanding dust to evaluate the patched height.

ottom Line. Focus on the setting compound consistency because if it is too watery, the compound won’t dry correctly. Don’t be shy with how much setting compound you apply. You can always sand it down.
