With easy-to-follow steps and expert tips on how to repair drywall with exposed gypsum, you’ll be able to restore your walls to their former glory in no time. So put on your DIY hat and let’s get cracking!

What is Exposed Gypsum?

Before diving into the repair process, let’s first understand what exposed gypsum is. Drywall is typically made up of a gypsum core covered with paper on both sides. The paper provides structural support and helps to create a smooth surface for painting or wallpapering.

However, when the paper covering gets damaged or removed, it exposes the fragile gypsum core underneath. This can be a problem as gypsum is not meant to be exposed to moisture or impact, making the drywall vulnerable to further damage.

Tools and Materials Needed

To successfully repair drywall with exposed gypsum, you will need the following tools and materials:

  • Joint Compound
  • Drywall Knife
  • Sandpaper
  • Taping Knife
  • Drywall Tape
  • Utility Knife
  • Primer
  • Paintbrush or Roller

Be sure to have all of these items on hand before starting the repair process.

10 Step-by-step Guides on How to Repair Drywall With Exposed Gypsum

Step 1: Prepare the Area

Laying Down a Drop Cloth or Plastic Sheet

Before starting any repair work, be sure to protect your floors and furniture by laying down a drop cloth or plastic sheet. This will prevent any debris, dust, or joint compound from damaging your belongings. You can also use painter’s tape to cover any edges or corners that you don’t want to get paint on.

It’s always a good idea to wear protective gear such as gloves and goggles while working with drywall. You don’t want any accidents or injuries to occur.

Step 2: Clean and Dry the Area

Using a damp cloth, clean the area around the exposed gypsum to remove any dust or debris. Then, using  a dry cloth or hairdryer, thoroughly dry the area. It’s essential to have a clean and dry surface before applying any joint compound. But make sure not to apply too much pressure while cleaning, as this could further damage the exposed gypsum.

Step 3: Cut Away Any Damaged Paper

Using a utility knife, carefully cut away any damaged paper around the exposed gypsum. You want to create a clean edge around the hole or area that needs repairing. This will make it easier for the joint compound and drywall tape to adhere properly. You can also use a drywall saw for larger or irregularly shaped areas.

Step 4: Apply Drywall Tape

Measure and cut a piece of drywall tape to fit the size of the hole or damaged area. Then, using your taping knife, apply a thin layer of joint compound over the exposed gypsum and onto the edges of the surrounding paper.

Place the drywall tape onto the joint compound and use your taping knife to smooth out any air bubbles or excess compound.

Step 5: Let it Dry

Once the Drywall Tape is in Place

Once the drywall tape is in place, let it dry completely. This usually takes around 24 hours, but follow the instructions on your joint compound for a specific drying time. It’s crucial to let it dry completely before moving on to the next step.

You don’t want to rush the process and end up with a subpar repair job. It’s worth the wait for a long-lasting fix. This is also a good time to clean up any tools or materials you used in the previous steps.

Step 6: Apply Another Layer of Joint Compound

Once the first layer of the joint compound is dry, use your drywall knife to apply another thin layer over the tape. Make sure to feather out the edges so that they blend seamlessly with the surrounding wall. You may need to apply multiple thin layers, allowing each one to dry completely before moving on to the next.

Step 7: Sand it Down

Once the final layer of the joint compound is dry, use sandpaper to smooth out any imperfections or ridges. This will create a smooth surface for painting or wallpapering over.

Be sure not to press too hard, as this could cause further damage to the exposed gypsum. It’s always better to sand lightly and do a few passes, rather than pressing too hard and creating a dip or hole in the wall.

Step 8: Prime the Area

Before Painting or Applying Wallpaper

Before painting or applying wallpaper, be sure to prime the repaired area. This will create an even base for your paint or wallpaper to adhere to and prevent any noticeable differences in texture. Use a paintbrush or roller to apply a coat of primer and allow it to dry completely. It’s also a good idea to prime the surrounding areas, so everything blends seamlessly.

Step 9: Paint or Wallpaper

Now comes the fun part – painting or applying wallpaper! Use your desired method to cover the repaired area and let it dry completely. You may need to apply multiple coats for a seamless look.

This is also a good time to touch up any surrounding areas if needed. But be sure to let the paint or wallpaper dry completely before moving on to the final step. It’s always better to wait a little longer for the best results.

Step 10: Admire Your Handiwork

Congratulations, you have successfully repaired drywall with exposed gypsum! Take a step back and admire your handiwork. Your walls are now as good as new, and no one will ever know there was once a hole or damaged area.

Remember, patience and attention to detail are key when it comes to repairing drywall. It’s always better to take your time and do the job right for a long-lasting fix.

Following these steps on how to repair drywall with exposed gypsum will guide you through the process of repairing drywall with exposed gypsum, resulting in a seamless and professional-looking finish.

Just remember to always use caution when working with drywall and take your time for the best results.  Happy repairing!
