You’re moving furniture, horsing around, or hanging something up and all of a sudden you have a hole in your drywall. You look at the wall and think, I’m not gonna fix that! I don’t know how or it’s too difficult. So, you do one of two things. You either hire and expensive contractor or you leave an unsightly hole for, what seems like, eternity.
Drywall repair does not have to be hard or expensive. The average person can do it with little effort and supplies. You simply need a utility knife, framing square, drywall, hand sander, putty knife and joint compound.
How To Repair A Drywall Hole:
Step 1: Damaged Drywall Removal
Use the framing square to mark a square around the entire damaged area, including any cracks. Be sure to make the marked area several inches bigger than the damaged area. Then use the utility knife to score along the marking in order to remove the damaged drywall.
Step 2: Tracing An Identical Drywall Patch
Carefully remove the damaged area as to keep it in one piece. Use this piece as a guide to mark an identical square from the new drywall. Cut the new square out with a utility knife. Be sure to keep clean edges on the square patch.
Note: Should you get protruding drywall hunks along the sides of the square patch, run the length of your utility knife blade at a 3/4 angle along the drywall edges to shave off any bulky pieces.
Step 3: Inserting The Drywall Patch
Next, use your putty knife to apply a layer of joint compound around the edges of the square patch. Then, carefully slide it into place. Use the putty knife to apply a layer of joint compound on all four seams. If there are any gaps, be sure to fill them with the compound. Allow this to dry overnight.
Note: If it is a small enough hole, you can cover the whole square with a layer of joint compound. Be sure to use a big trial and keep it clean as you take off any excessive compound.
Step 4: A Smooth Finish
After the compound is dry (white, not grey), sand the drywall until it is smooth and level with the surrounding drywall. If the joint compound has become uneven or shrunk while drying, it will be necessary to apply another layer of compound after it has been sanded. Once it is dry, sanded and smooth, you may paint the drywall.
How To Repair A Surface Crack In Your Drywall :
A surface crack is when the visible drywall/paint is cracked but it is only on the surface, meaning that the paper on the back of the drywall is not torn. Thus, it is cracked and not a hole.
Step 1: Cut Out The Crack
Using your utility knife, gently score just around the crack. Be sure to not dig the knife in too deep or you will tear the paper backing. Then lightly dig out any loose drywall from within the cracked area with the point of your utility knife.
Step 2: Fill The Crack
Fill the area with joint compound and use a large putty knife as you wipe excess compound away. Allow to dry overnight and repeat if necessary.
Note: A bigger putty knife than the one displayed below is best.
