If you’ve ever been curious about how to tape drywall, you might be pleased to discover that it really isn’t as hard as you might first think! Taping drywall is the act of concealing the lines (joints) formed by adjoining drywall panels. This process is what makes walls look nice and smooth.
Drywall tape is either made out of paper or plastic (vinyl) and it comes as roll like most tapes do. Interestingly, there is no adhesive on the back of drywall tape. It adheres to a wall with the use of joint cement (mud, plaster, or compound).
