How to Fix a Drywall Crack

If you find a crack in your drywall, don’t panic. Your house isn’t falling apart.

In fact, small drywall cracks are normal, often appearing as a result of the house settling. And they’re easy to fix.

Instead of spending a bunch of money on a professional, take a look at this complete guide that’ll show you how to easily repair a drywall crack.

The Tools You’ll Need

Before you get started, make sure you have the right tools for the job.

If you try to use other tools you have lying around the house as “supplement tools,” you won’t make it very far into the project before you have to stop and buy the right tools anyway.

So, here’s what you’ll need:

  • Utility knife
  • 6-inch Taping knife
  • Mud pan (you don’t necessarily need a mud pan, but it will make it easier to apply drywall compound to the taping knife.)
  • Drywall compound
  • Fine-grit sandpaper
  • Paper drywall tape (fiberglass drywall tape is thicker and harder to repair visually. So for this guide, we will focus on paper drywall tape.)

Step 1

The first thing you need to do is clean out the crack. Take your utility knife and cut off any rough edges and to scrape away any loose material from inside the crack.

Step 2

Put some of the drywall compound into the mud pan and get a small amount on your taping knife. Apply a thin coat of compound over the crack.

Step 3

Cut a piece of tape long enough to cover the crack. If the drywall crack is an odd shape, you can cut small pieces of tape to follow the zigzaggy pattern.

Then place the tape immediately onto the drywall compound. You should put the tape on as quickly after you apply the compound as possible.

If you have a long or oddly shaped crack, it may be a good idea to cut the tape before you apply the compound.

Step 4

With the taping knife, push the drywall tape into the compound.

Make sure there aren’t any bubbles. If there is air under the drywall tape, it will stay there forever, creating a little bump on your wall. Make sure there aren’t any bubbles. If there is 

Apply another layer of compound over the top of the tape and wait for it to dry. (Drying may take several hours or even overnight.)

Step 5

Apply a second coat over the top. Make sure the edges of the compound blend with the rest of the wall. Don’t layer the compound too thickly or it will bump out from the wall.

Step 6

After the second coat is dry, apply a third and final coat. Again, wait for it to dry.

Step 7

Sand the patch of drywall compound with your fine-grit sandpaper until it is smooth. But be careful not to sand down to the drywall tape.

When you’re done sanding, you can repaint the patch the same color as the rest of your wall. Don’t forget to use a primer though.

If you don’t, the color won’t match your wall completely.

That’s All It Takes to Fix a Drywall Crack

The hardest part of this project is waiting for all those layers to dry. Everything else doesn’t take a lot of work and can be done quickly and easily.

7 Drywall Types and Their Uses

Depending on the project and where they will be installed, there are many types of drywall.

But the real question is.. Which is the right type of drywall for your project?

To help you better understand the 7 drywall types and their uses, we’ve put together a list:

Regular Drywall (White Board)

Regular drywall — also known as “White Board” — is the most common and comes in 4 x 8 panels, ranging from ⅜ inch to 1 inch in thickness.

To determine whether or not it is regular drywall, check to see if one side is white and one side is brown.

White board drywall is the most economic drywall type on the market.

Green Board Drywall

Green board drywall is mostly used in bathrooms, basement walls, kitchens and laundry rooms as the green side is known for being moisture resistant.

Although it is moisture resistant, it is not completely waterproof.

Keep in mind that green board drywall is more expensive than regular drywall.

Blue Board Drywall

Blue board drywall — also known as “Plaster Base Board” — is mostly used for veneer plastering.

Since the surface paper has special absorption qualities, it has a high water and mold resistance.

Like green board drywall, blue board drywall is works extremely well in bathrooms or places with a lot of moisture.

This type of board helps reduce noise but it is not made for tape, paint or mud.

Paperless Drywall

Unlike other drywall types, paperless drywall is covered with fiberglass to keep the gypsum board from rotting and help provide a greater resistance to mildew and mold.

The quality of the board is a bit rougher than regular drywall, but it makes for an easier cut.

Due to the roughness of the fiberglass, applying joint compound to smooth out the surface is recommended.

Purple Drywall

If your drywall is going to be in contact with water, this is the one to use.

Purple drywall has the same feel and sizing as regular drywall, but it is much more resistant to moisture and mold.

Construction pros typically hang this type of drywall in ceilings and walls where there’s an increase in moisture, such as a bathroom where steam is created.

Type X Drywall

“Type X” drywall is made with special noncombustible fibers and normally used in garages, rooms and apartment buildings in case of a fire.

Several thicknesses can be used in layers to increase its fire rating, but it normally comes in ⅝ thickness.

Due to its thickness, it is harder to cut and work with than regular drywall.

This so-called fire-resistant drywall is required by several building codes.

Soundproof Drywall

Soundproof drywall is denser than regular drywall and is made with a mix of wood fibers, gypsum and polymers in order to increase its soundproofing characteristics.

This type of drywall is normally used in rooms where noise will be increased, such as a family room.

If you are a musician, this type of drywall would be perfect for your music room.

DIY or Call a Professional: Tips for Fixing Your Drywall

Drywall services underway

Is drywall installation or repair a part of your upcoming home improvement project?

Did you know damaged drywall can create a number of hidden dangers in your home?

If you’re not sure where to get started with fixing your drywall, here are 6 tips to help you determine whether you can DIY the job or hire our professional drywall services!

Common Types of Drywall Damage

Drywall damage can occur in a number of ways.

Small surface cracks often occur at the juncture of two sheetrock panels. Minor dents, dings, and scratches result from doorknobs, moving furniture, kids, or regular wear and tear.

When a crack extends into the paper or throughout the seam’s tape it is considered a deeper crack.

Drywall damage related to water damage, such as leaks or flooding, can create erosion, sagging, or holes. This type of damage is a breeding ground for mold and can also create electrical or structural hazards.

Drywall Tools and Supplies

If you plan to DIY your drywall repairs, you’ll need a few tools that can be sourced from Home Depot, Lowes, or any local hardware stores.

Here’s a quick list of tools and materials you’ll need:

  1. Dust mask
  2. Mud pan
  3. Drywall mud or putty
  4. Painters tape
  5. Putty knife
  6. Utility knife
  7. Paper drywall tape
  8. Joint compound (pre-mixed)
  9. Setting compound

Depending on the extent of damage and your walls, you will probably need a sanding tool or sandpaper and paint to match the rest of the wall.

Assessing the Drywall Damage

The first step in a drywall repair project is to assess the damage.

First, ask yourself how the damage occurred. If it is water-related damage, be prepared to check for mold buildup and damage extending past the immediate area.

Drywall Repair Process

After assessing the damage by eye, you can begin the repair process which also starts by evaluating cracks.

For superficial cracks, use a chisel to widen the crack to see if it extends throughout the paper along the seam.

For small holes in the drywall, fill the hole with the drywall mud, scrape it until it’s flat. Once it’s dry, sand it until it’s flush. For larger holes, you’ll need to make a patch with a piece of drywall.

Hiring A Drywall Professional

Hiring a professional contractor for drywall services can take a lot of the headache out of assessment and repairs.

A professional will know how to evaluate the damage immediately. They will have all the necessary tools and be able to source materials at a cheaper cost. They will also bring a team on board, if necessary.

For larger projects and water-related damage, hiring a professional to repair or replace your drywall is a surefire way to get the job done safely, quickly, and at a low cost.
