Technical Information

Installation

1. Apply a generous amount of approved joint compound to a clean, dry surface of drywall.
2. Place the No-Coat corner onto wet joint compound and press on firmly.
3. Using a stiff 4 inch to 6 inch taping knife or an appropriate No-Coat roller, wipe very hard, squishing the excess mud out from behind the No-Coat corner trim and embedding the mud into both the paper fibers of the drywall board and the joint tape paper surface of the No-Coat corner.

• ULTRAFLEX corners are first aid for damaged off-angle corners. Keep a roll on hand for fixing cracks, peels, chips and dents. No-Coat’s thin corner profile allows you to repair damaged drywall corners without a buildup of product.
• When installing ULTRAFLEX corners, preflex the material and run a pencil down the apex of the corner for a clear reference point (similar to a chalk line).
• If you are installing ULTRAFLEX corners on a long span off-angle by yourself, you can use a tack pin to hold it in place before the mud sets. Then, remove the pins and adjust the corner as you wipe it down.
