TIPS

•  NO-COAT drywall corners have a built-in flexible hinge that can adjust to any angle. If a wall is far out of plumb, simply pinch the NO-COAT corner trim and adjust it accordingly. We also recommend applying an excess of All-Purpose joint compound to compensate for large gaps.

• When storing ULTRATRIM corners, lay boxes flat on the floor. Leaning boxes against a wall may eventually cause the corners to warp.

• Tape and coat drywall board seams and ceiling joints before applying NO-COAT drywall corners. This will create a smoother surface for corner trim application, and a straighter finished profile.

1. Using a 4” – 6” taping knife, apply All-Purpose joint compound to drywall slightly beyond where the edge of the corner will be.

2. Place ULTRATRIM Inside 90 corner on wall and press into position by hand. The joint tape side (with the NO-COAT logo) of the corner goes against the drywall. Corner should be aligned tightly to the ceiling.

3. Embed trim by using a NO-COAT ULTRATOOL INSIDE 90 Roller or by running the knife over it with even pressure at a 45 degree angle to press the corner into position.

5. Using a 6” – 8” finishing knife, skim over the corner with All-Purpose joint compound once more. Let dry. Sand and paint.

The NO-COAT  Double Barrel Hopper
The NO-COAT  Hopper accommodates all inside and outside angles without time-consuming part changeovers and reconfigurations.

TIP: Before filling the NO-COAT Double Barrel Hopper with All-Purpose joint compound, run a short piece of corner through the Hopper gates. This allows you to make the most accurate tolerance adjustment. To avoid run off, compound should have the same consistency as boxing mud.
