Fiberglass mesh tape is easier to use than paper tape. Paper tape needs to be pressed into a layer of compound and the excess compound removed. The trick is that you must remove surplus compound without wrinkling the tape or removing so much that the tape buckles because you've created dry spots. Faced with all of those paper tape challenges, you'll probably agree that fiberglass tape is worth its extra cost.
When you buy fiberglass tape, ensure that the package indicates it's self-adhesive. While the nonadhesive version is scarce, getting a roll could be an unpleasant surprise.
Be sure you keep a sharp utility knife blade available to cut fiberglass tape. A dull blade will merely skip over the fabric or snag the threads. If you're tackling a big project, consider getting a tape dispenser. It's a speedy helper for both flat seams and inside corners. Below, we show you how to effectively use fiberglass tape.
