I live in a double-wide mobile home. Of course like any mobile home, I have strips of one 1/8 inch by 1 inch strips of wood about every 3 to 3.5 feet covering up the joints where the dry wall comes together. I am in the process of removing all the strips and putting joint compound on them to smooth out my wall and painting. Self tought and looks pretty darn good. My question is... I am unable to get the corners looking smooth and nice. Some of my walls have anywhere from a 1/4 inch gap to a 1/2 inch gap under strips. Whatever company put my home together cannot measure. One corner from inside wall to outside wall had one inch gap. And there is not a straight line anywhere.I have used all the drywall tapes available and still am unable to get my corners defined. Is there a special corner tool out there or is there a special trick. If anyone can help me I would greatly appreciate any advice. The only other choice I am able to come up with is to put corner-round molding in corners to make it look better.

There is a special dry wall tape for corners that has metal edging embedded in it. It allows you to fold the tape down the middle and apply to your corners. It comes in a box, rolled up into itself. I cannot remember the name of it right now. You mud the corners, put in the tape, and then mud over tape.

It's worked pretty well for me in the past. I'm sure some of the pros have other suggestions as well.

Home depot has a trowel that is designed for inside corners. It is shaped at about an 85 degree angle and top edge is about 5 inches each side of angle. Sorry can't provide a picture. The store by me has them with trowels in paint dept.

Also there is a preglued mesh that measures 6 inches.

Fill the crack with compound and let dry overnight. This will give u a backing for the tape

Good luck

I personally don't like the V shaped trowels, You push to hard and it sallow in the inside corner and to thick on it outer edges and that's what yopu don't want on finish work

Mud in hollow corner gaps. They to get a close inside edge. Get and USE regular drywall tape. Ripp off an 8 foot piece. Now look at the center of the tape and it has a crease in it Bent and partially fold it there. Mud wall on both sides. Now use trowel to blade down the inside corner to make that corner line. After the RE mud only one side of the inside corner and blade it down again. Let that set up. Now you have a fairly goo straight corner. Mud the other side of that corner and when you blade down that side the other side is dry/stiff as not to mark it while you blade the opposite side.

Trick here for the novice is do one inside of the inside corner to Control That line for being straight.

Hi I Own a drywall co in wi what you can do is pre-fill the gaps and then use a paper tape in the corner you should use the tape on the other joints to prevent cracking also but in the cornes the way to do them after they are taped you coat 1 side of the corner with drywall compound wait for it to dry over night coat the other side and then sand

In addition to what arby said - 45 or 90 minute compound is good for corners as you won't have to wait overnight to do the other side and it dries hard.
