Why is sheetrock tape bubbling?
Why is sheetrock tape bubbling?
A common reason for an air bubble to appear under drywall tape is improper installation. The bond between the drywall compound and the drywall tape is not adequate. You need to fix the air bubbles before finishing the joint, as ripples in the tape left unfixed would be evident after the wall is painted.
Do you have to tape every drywall joint?
Do you have to tape all drywall joints? All drywall seams need to have tape embedded in joint compound. The tape strengthens the joint, and the joint compound, or mud, is the adhesive that holds the tape in place.

Can you use mesh drywall tape on inside corners?

How do you calculate drywall mud and tape?
As a general rule, estimate 0.053 pounds of mud per square foot of drywall. So, multiply the total number of square feet by 0.053 to determine how many pounds of compound you’ll need. For example, if you are putting up 1,600 square feet of drywall, you would need: 1,600 x 0.053 = 84.8 pounds of compound.
