Designed to help you quickly and easily apply paper or plastic corner bead to your drywall, this 3M adhesive spray provides reliable adhesion on the job.Run a length of Fast Edge through a hopper, or use a knife or compound applicator tube to apply mud directly on the drywall. Remember we have a trade counter where you can come and pay with a credit card and someone will pick your goods for you while you wait. Combining this spray with staples along its mud leg gives the corner bead a strong bond to the drywall that has been proven to last. The tried-and-true technique for outfitting your corners with toughened vinyl, just because this method is conventional doesn’t mean it’s not highly effective. Spray continuously from a distance of 6 to 10 inches, being sure to keep the spray moving to avoid buildup on the drywall or bead surface.

If you’ve installed a metal corner bead, a good whack will dent and deform its nose — this kind of damage is irreparable, and you’d have to replace any affected section, or rip the whole thing out and start again.Press the corner bead in place using a pressuring tool or the handle of your taping knife and finish by stapling every six to eight inches — Trim-Tex recommends using half-inch staples. Where standard vinyl will require around three coats of mud to finish, you’re already prepared to move on to your next project with the Fast Edge installation method. Excess mud will squeeze through the perforations, which essentially levels out the bead from sitting too high on the corner; it also minimizes the amount of mud needed for the setting coat to form an incomparably strong bond between the bead and the drywall. Fast Edge also utilizes the Mud Lock Technology we previously discussed for extra-strength adhesion, but with no mud holes, excess compound gets pushed out the back of the bead.

If any damage does occur, it’s almost always going to be the drywall mud that fails, which you can fix with a quick patch. However, as you can see in the pictures the drywall seems to be not all the way to the corners and is damaged in some places. Achieve professional results without the need for nails, screws or staples with 3M 61 Drywall Corner Bead Spray Adhesive. When you said it's still soft, and it cracked: it sounds like a thick layer of mud is still still shrinking as it dries.

The strength of the bond between the mud legs, drywall compound and wall, combined with the elasticity properties of rigid vinyl, allow the bead to withstand a high degree of impact. Then try to fill in with fast setting compound, to a square corner that will properly receive the new bead. It includes 3M Drywall Spray Adhesive 61, 3M Super 77 Drywall Corner Bead Adhesive, and Trim-Tex 847 Spray Adhesive.
