No Coat
No-Coat is a product that is made with plastic covered in paper for inside and outside corners. Available in 100ft rolls and sticks 8ft, 9ft, 10ft, and 12ft. Benefits are a better bond to the drywall and better ability not to dent when impacted. It is glued on with joint compound instead of nailed or screwed like corner bead.
"No-Coat" refers to an innovative drywall corner system with a strong copolymer core and paper tape, designed for durable, crack-resistant, and perfectly straight interior/exterior corners that install faster and stronger than traditional metal beads, often requiring fewer mud coats for a smooth, professional finish. It's also a term for a "no-wipe" gel top coat in nail care, which cures without a tacky layer, unlike standard top coats that need wiping.
