How to Fix a Crack in Drywall That Keeps Coming Back

Home improvement projects can seem as though they will never end. Especially when small problems keep popping up like cracks in your drywall. This can be a pain to fix when you are living a busy life. Especially you have a crack in your drywall that you have repeatedly fixed to no avail, it can be extremely frustrating. 

Whether you have a crack, or you have accidentally made a hole in the wall, fixing a crack should be easy. Essentially, even if you think you might be fixing it properly, often you might be missing a key step or ingredient.

The best way to fix a crack in your drywall is to use 3M’s Patch Plus Primer. This method will help you to permanently fix a crack in your drywall so you can avoid repeating the process again.

Materials Needed

  • Fiberglass mesh drywall tape
  • 3M Patch Plus Primer
  • Putty knife
  • Drywall knife
  • Mud pan
  • Sanding sponge
  • Towel
  • Paint that matches your wall


Step 1: Attach Fiberglass Mesh Tape

The first step you will need to perform is to apply fiberglass mesh tape directly to the crack in your drywall. Although most people simply add joint compound or spackling onto the crack. This is not the right thing to do because it will eventually break apart. 

When you add fiberglass mesh drywall tape to the actual crack, you will add an extra layer of protection. This is similar to if you are patching a hole in your wall.

Be sure to center the tape on the crack, set it on the wall. Then get your Patch Plus Primer ready for the next step.

Step 2: Apply Patch Plus Primer

At this point, it is time to add a thin layer of your patch plus primer on top of the drywall tape. Using 3M Patch Plus Primer is great because you will not need to use a primer coat. This will save you money as well as time.

When you buy your 3M Patch Plus Primer at the hardware store, make sure it hasn’t been opened. For some reason, this occurs often, and it can completely ruin the mixture.

Get started applying a thin coat of Patch Plus Primer over the mesh tape. It should only fill the spaces and make it attach to the wall.

If you have a large crack (larger than two feet) then you should use a drywall knife that is at least six inches long. In order to use a knife this large, you will also need to put some of your Patch Plus Primer into a mud pan.

Begin spackling in the middle of the tape and moving outward. Do so in a downward motion. Then you can go back in and add more spackling going upward from the center of the tape. This will help you to avoid wrinkles.

Let this dry, it will not take longer than 30 minutes.

Step 3: Second Coat

The reason you originally put a light coat on the 3M Patch Plus Primer is that you want it to be smooth. This step involves a second coat. 

Take your knife once again to apply the second coat of the Patch Plus Primer. Make sure that the width of the new coat is at least two inches larger on both the left and right of the tape.

Carefully smooth out the spackling with your drywall knife and move, once again, from the center outwards. Try to apply more pressure on the side of the knife that is on the drywall. This will allow you to blend it much better.

Allow it to dry for another 30 minutes and take a look. You may need to apply a third coat depending on what it looks like. This will fully depend on both your skill and the level of perfection you are hoping to achieve. 

Step 4: Sanding

Now, you will need to grab your sanding sponge. This should be of fine-grit and will be used to feather the edges even more. Take your sanding sponge and lightly sand the Patch Plus Primer.  

Move the sponge over the area in a circular motion to properly blend it into the drywall. At this point, it should look almost perfect. 

Step 5: Painting

Since 3M Patch Plus Primer does not require you to use a paint primer, you will be ready to begin the painting process. Another amazing aspect of Patch Plus Primer is that you only need to wait 30 minutes between each coat. 

In order to match your wall, you will need to have the same paint color that you originally painted it with. Be aware, if your paint is over two years old, or it is in direct sunlight, it may no longer completely match. The worst-case scenario is having to paint the entire wall. 

Take a good quality brush or roller and paint in downward motions. Try to avoid putting too much paint on the parts that are already painted around it. This can make them darker or lighter depending on the color.

After you are done, rinse your brush in warm water. You can then wrap it in some type of plastic wrap to keep it looking nice and new. 

Congratulations! You should never have to go in and fix that crack again.

What if I do not have my original paint to match my wall?

There are a few things you can do if you do not have original paint to match your walls. If you used paint that is from a swatch, then you can simply go and buy the same paint. The issue comes when the paint is faded due to being old or in direct light. 

The solution to this is if you can take a one-inch piece of the paint off of the wall. Since you will be spackling over it, it shouldn’t be an issue. If you bring this to a hardware or paint store, they should be able to color match for you.
