Bigger cracks take a little more effort to deal with. Are all cracks bad? A big crack in your drywall is bad.

Got another drywall problem? See 'Drywall Repair' for a listing of drywall topics and 'Drywall Patching' for information about fixing drywall.

You want to remove any loose paper and gypsum from the crack. Use a utility knife or a scraper to clean out the debris.

It is a good idea to fasten the drywall with some screws. Try to locate the studs and run some screws into them on either side of the crack. This will stabilize the drywall and hopefully keep it from cracking again.

Set the screws so that they are sunken into the drywall. Not so far that it breaks the paper, but far enough so that the mud will 'key' into the indentation. Drywall screw guns have a depth gauge for this. Using a battery drill will work, but you have to use a light touch. Ease the screw in and pull back just as it starts into the paper.

How wide is the crack? Is there a gap? For cracks that have a separation between the two sides you should pre fill them with drywall compound. These would be cracks where, there is clearly a separation.

Use a knife that is wider than the crack. With stiff drywall compound (right out of the pail without any water added), pack some mud into the crack. Drag the knife lengthwise with the crack, removing the excess mud. You should keep the knife tight to the flat portion of the wall. Check and make sure you have filled the crack completely. Add some mud and drag it again, when you see voids.

Now put down the knife and step back from the crack. Let the mud dry before you try and tape it. At this point the crack is ready for the mud and tape. You have a few steps to go for this drywall crack repair. Don't despair, others have survived and not been seriously damaged.

Fixing Minor Drywall Cracks

A minor crack can be fixed with spackling, once you have cleared away the loose material.

Examine the crack. Is it just a hairline crack? Take something and dig into the crack a little bit. You probably won't believe this, but the tool I like for this job is the sharp point of a bottle opener. When you dig a small groove into the crack does it appear that the paper below is still intact? Yes, that's good, this won't be that hard.

Use something, like the 'bottle opener', to dig out the crack. You want to dig out the loose material and create a groove to accept some new mud or compound. Dig it out the entire length.

Be careful you don't want to make the situation worse. Make sure you have all the loose material removed. Additionally, you want to have a place for the mud to 'key' into (it's an old plastering term). The more area the mud has to stick to, the better.

Now all you have to do is fill the crack with compound or spackling. Use a knife that is wider than the crack. Pull the mud tight against the flat surface of the wall on either side of the crack. It will take two or three applications to get a smooth surface. Use a sanding sponge to lightly sand the area after each coat. For additional information go to the article 'How to Spackle Drywall'.

Taping and Mudding Drywall Cracks

Taping and mudding a drywall crack will involve a few steps. You will need to let the mud dry between each application.

The following is the steps you need to follow to tape and finish the crack. For complete instruction of drywall finishing, see the article 'Taping and Mudding Drywall'.

Applying the Drywall Tape

You can use paper drywall tape or fiberglass mesh tape to repair the crack. Mesh tape will save a step, allowing you to coat it immediately after the tape is installed.

Make sure you completely cover the crack and have the tap onto solid wall surface. This may mean that you have more than one width of tape. If you use paper tape, make sure you have compound between the layers of tape.

Coating the Crack With Compound

You will likely have to apply two coats of compound and a skim coat to get a nice finish. Lightly sand the high spots down between each coat.

Do not try to do too much with each pass. The first coat will be the heaviest. You want to completely cover the tape and feather the edges toward the flat surface of the wall.

Allow the drywall mud to completely dry before you apply another coat of mud. Skim the repair with a wide knife on the third pass to eliminate in hollow spots and tool marks left from the previous passes. See the article 'Taping and Mudding Drywall', fior additional instructions.

Sanding and Painting

Sand the repair lightly until you have a smooth surface suitable for paint. Paint the wall and your crack is gone.

Drywall crack repair differs from other drywall repairs in one key way. As a rule there is no obvious reason why a crack appears.

For related information see the articles 'How To Patch Drywall', 'How To Cut Drywall' and 'Taping and Mudding Drywall'.

Cracks in drywall will occur for two reasons in residential construction. There are probably more than two, but I am not going to discuss them. One is settling, over time the house will settle and the drywall may crack due to the stresses put on it by the structure. You don't want to blame the drywall, it is doing its job. The second reason would be ill advised placement of joints in the drywall.

The bad news is that if the problem that caused the crack is still there, the crack may reappear. Stopping a house from settling is not possible and repairing subtle structural problems is also not practical. The likely case scenario would be to fix the drywall and hope the crack does not reappear.

Drywall Crack Repair - The Issues

Troubleshooting Drywall Cracks

There are two types of cracks to address. The first and easiest is one that has not broken through the tape or paper on the drywall. The second is a severe crack that may have split the drywall all the way through. Even if only the paper is broken, you will have to use tape to bridge the gap.

The first article on 'Causes for Drywall Cracks' provids some insight into the reasons for cracks. It also explained why some of them come back after they are fixed.

Some cracks are fairly minor and only require filling and sanding. When does a drywall crack become a serious issue? When the paper face of the drywall has been compromised, you will need to apply new tape. The article 'Fixing Cracks in Drywall Walls and Ceilings' coversd this topic.

Fixing a crack will involve the use of mud and tape. There are steps you need to follow when you are patching drywall cracks. The article 'Taping and Mudding Drywall Cracks' gave you the information you need to perform this task.

Summary

They say that drywall installers and finishers are a breed of their own. That is probably because not too many people like doing it. OK, it was several steps, but none of them should have taken that long. The trick is to be patient. Allow a drywall crack repair to run over the course of a couple of days. Find other things to do while the mud is drying.

We hope that your experience with drywall crack repairs has not been too traumatizing. From this point forward, try to forget the past and move forward. Cracks may occur in your drywall again. Now you have the strength of character to face up to them.
