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.
Are inside and outside corner beads the same?
The outside corners are a direct replacement for metal corner bead. The inside corners are replacement for folded paper tape. Because the beads hold their shape they form crisp inside and outside corners.
Should drywall corners overlap?
It doesn’t matter for the walls, although it is standard practice to put drywall on the ceiling first so that the edges rest on the top edge of the drywall that you apply to the walls.
How many coats of mud do inside corners need?
If your wall has distinct crevices, cracks, or textured areas, or if your brand of drywall mud isn’t offering enough coverage, you may have to do a couple of additional coats of compound. However, in general, you’ll need one coat to fill in the seams and three more coats after taping.

How do you tape an inside corner with mesh?
Using mesh tape: If you use mesh tape on inside corners, apply it before the compound. Push the tape tight into the corner so it is centered and free of wrinkles. Generally, the paper tape is embedded in a layer of joint compound and then covered with one or two thin coats.
What is the difference between an inside corner and an outside corner?
Inside corner moldings tend to appear triangular in shape and are designed to be set into a corner such as the one underneath the countertop. An outside edge molding is typically “L” shaped and is attached to an edge to cover the original raw corner of the cabinet such as those along the bottom edge of top cabinets.
