Strait-Flex® Original

Flexible Corner Bead Composite

Installation

  1. Cut Strait-Flex Original to the desired length and trim the ends at 45-degree angles. Fold Original in half at the center crease, with the print-sides facing themselves. For outside corners, fold more than the desired angle with the print-side facing the wall. For inside corners, fold less than the desired angle with the print-side facing out.
  2. Apply all-purpose compound to corner. Press Original into the wet compound, adjust, if necessary, to create a straight line and wipe down tight and smooth with a taping knife.
  3. The first finishing coat of compound can be applied immediately. Let this dry completely, for several hours or overnight.
  4. With a 6″ or 8″ taping knife, apply your final coat of compound, feathering the compound beyond previous coat. For inside corners, a very light coat of compound is all that’s needed. Let this dry completely, for several hours or overnight.
  5. Sand lightly with 120 grit sandpaper. Original will not fuzz-up like paper or mesh tapes.
  6. Alternatively, Strait-Flex Original can be installed on an outside corner with the print-sIde tacing out. Installing Original in this manner means that the products pronounced nose will face the wall, allowing the corner to be finished without a nose. Additionally, installing the product in this fashion allows the flock backing to face the wall, which increases bonding strength. Be aware that excessive wiping using this method could cause too much mud to be removed from the backside of the product – in the event that this happens, you may experience flange pop due to the “memory” of the hinge in the nose of Strait-Flex Original. It is due to this nuance that we recommend installation with the print-side facing in on an outside corner, however, you can achieve the same fast, straight, and strong finish installing the product in both fashions.
