Is There Special Mud & Tape for Vaulted Ceiling Joints?

Significance

• Many new homes have vaulted ceilings, sometimes called cathedral ceilings. These ceilings often require professional drywall finishing because of the angled joints.

Function

• Joints are where two drywall boards meet. To finish them, you must embed drywall tape in joint compound over the joint so that the seams will not be visible through paint.

Types

• If two drywall boards are level with each other, or if they roughly are at a 90-degree angle to each other, you can use normal paper drywall tape.

Considerations

• Vaulted ceiling joints are often obtuse, meaning they are somewhere between 90 and 180 degrees. These require special tape for finishing.

Expert Insight

• Two popular brands of obtuse angle tape are No-Coat and Strait-Flex. Neither requires a special type of joint compound for installation.
