Why does my repair on drywall crack after it drys?
I am trying to repair some cracks in my drywall and it keeps cracking after it drys. Am I putting it on too thin? I did tape it first, but the joint compound is getting a crack after it drys??? Any clues? It is a crack repair around doors and windows. I am letting another coat dry right now, hope that this is the last one. Just am getting frustrated, I want to get on with my painting!

I do not know what you are using to repair your wall, but it sounds like you might be using the wrong product. You should be able to pick up a bag of "easy sand 20" made by the sheetrock people at any home center or decent paint store. Mix it with WATER to a consistency of peanut butter. If the crack is 1/8 inch or smaller, you don't need tape..BUT, you need to clean out the crack and use a 5in1 tool to make a small groove behind the wall surface to act as a tooth. You will need 2-3 applications to get smooth, complete coverage with a professional look. Sand when completely dry with 220 grit paper. Prime with a decent latex primer and paint.

Yes you are putting it on too thin. Get sheetrock tape that is sticky. Its much easier to handle. Mud the tape generously, sand, re mud again. Sand, prime and then paint

what size hole`s are you filling,sometimes if the crack,or hole`s are to big,you should fill it a little at a time,if it cracks,just sand it down and put a nother coat on and so forth,until it is full.if you are applying new,don`t put to much on at onetime.

Answer 5
This will happen if you put a WET compound on a DRY wall, because the dry background will suck the moisture from the compound too quickly. Here is my suggestion, wet the background first, then apply the compound, you do not need tape for a minor repair like a crack.

Answer 6
the secret to joint compound is not to use water, but paint for its ELASTICITY (water will dry up, causing joint compound to crack). learned that from interior decorating..any color paint should work...white is cheaper good luck ;-)

Eve is rite.. another thing may be at falt here as well... the rock may not be secured on one side or the other of that crack.. try re-screwing both sides of the crack just to be sure. if you can, after you do that, remove your old patch and re-tape the crack, that way you will have solid rock to work with again insted of a floater. irritatinng, i know.. but in the end you will have a far better looking repair.

Learning how to drywall is not as difficult as you might think...there are a couple of things to keep in mind; drywall comes in thickness ranging from 1/4 inch to 5/8 inch; but 1/2 inch is the most common. A standard sheet measures 4 x 8 feet. Longer sheet are typically 12 feet. Either type of fastener will do the job, drywall screws or drywall nails. Unlike the nails, a screw gun will quickly drive screws to the correct depth, automatically, without ever damaging the drywall.
