![]() The ideal solution for repairing the bubbling or peeling drywall tape is to remove it and start over with the application of new drywall tape and joint compound. This is what causes the peeling or bubbling of the drywall tape. The drywall tape will absorb the moisture of the second application of joint compound and actually cause the drywall tape to wick away from the drywall. The situation is exacerbated when the next layer of joint compound is then applied over the tape. As a result, the drywall tape will not adhere to the wall sufficiently. Pressing too hard will cause the joint compound to be squeezed out from behind the drywall tape. This first application of joint compound is typically referred to as the “skim coat” or “bedding coat” layer, however it is important not to skimp too much when troweling on this first layer of mud / joint compound.Īs a matter of fact, drywall sheets are dimpled on the edges that are expected to butt up against other drywall sheets to allow for the drywall tape and skim coat of mud.Īlso, when applying the drywall tape to the seams that have been freshly skim coated it is important not to press too hard with the trowel. ![]() When applying drywall paper tape to the joints and seams it is important to first apply a liberal amount of joint compound (approximately 1/8th inch) to them. It is important when applying paper drywall tape that it be properly pressed into a skim coat layer of mud, or joint compound. If your new drywall work is showing signs of bubbling, or is literally peeling off your walls, then the paper drywall tape was not applied properly. ![]()
