Herein, can I use mesh tape on inside corners?
You can use mesh anywhere except inside corners. But mesh tape has one weakness (literally): It's not as strong as paper. To compensate, you have to cover it with setting-type joint compound, which is stronger than premixed compound (see tip below).
Furthermore, can you caulk drywall corners? In closets and other low-priority areas, don't tape and mud inside corners. Instead, caulk them. I first tried this trick on wall and ceiling corners 20 years ago—and those corners still look good. Finish all the tapered joints and get a coat of primer on the rock before you caulk.
Regarding this, do you need to tape inside drywall corners?
For a professional finish, you have to tape, then wait. The average house has as much lineal footage of inside corners as it does flat seams. A good system for taping and mudding inside corners improves the look of every room and saves time.
Is mesh or paper tape better for drywall?
In general, paper drywall tape is slightly stronger and more versatile, but mesh tape has a more manageable learning curve and better moisture resistance.
Related Question AnswersIs mesh tape better than paper?
Paper is not as strong as fiberglass mesh; however, it is nonelastic and will create stronger joints. This is especially important at butt joints, which typically are the weakest areas in a drywall installation. Paper tape can be used with either drying-type or setting-type compound.How big of a gap can you fill with drywall mud?
You can usually fill gaps less than 1/2 inch wide with joint compound while you are taping, but joint compound cracks when used to fill wider gaps. The solution is to fill the gaps with patching compound or, if they are especially wide, with strips of drywall.Do I have to sand between coats of drywall mud?
2 Answers. Yes, knock off any bumps between coats, but there's no need to get it perfect. A screen sander on the end of a pole is the best tool for this job. And it goes without saying that you should minimize any bumps while the mud is still drying to avoid having to sand it later.Should you overlap drywall tape?

Taping the metal corner helps to prevent cracks. If you don't want to go shopping for special corner bead, avoid future cracking by applying paper tape over the metal edge after you've nailed on the bead. Embed the tape just as you would on any joint. Then fill the corner as usual.Can you use metal corner bead for inside corners?
The answer, though, is simple: They cheat. They use a rigid material called corner beading, which can be made of metal or plastic. Inside corners don't need as much protection, so drywallers cover them with regular drywall tape. The process for finishing inside and outside corners is the same.How do you fix drywall tape corners?
Spread the hot mud on both walls that form the corner with a 4-inch drywall knife. Cut enough fiberglass mesh drywall tape to cover the seam, crease it lengthwise and lay it on top of the mud.

Place a drop cloth along the floor at the base of the wall in case any drywall or paint falls during the patching process.

To prep for painting corners, start by running the first piece of tape up the wall, making it a little long. Press the tape down into the corner with a putty knife.

Can you mud drywall without tape?
Drywall tape serves a single purpose: To help make the seams invisible. Drywall tape does not offer an mechanical strength at all. If you skipped the drywall tape and just used joint compound to fill in the seams, the seams would become visible again after the compound dried. Joint compound shrinks!How do you tape and float drywall?
