Strait-Flex® OS-300

DESIGNED FOR SQUARE, LOW-FILL OUTSIDE 90° CORNERS

Diamond-punched paper edging allows for easier feathering, faster drying, and high bonding strength, which assures even lay-down of the paper, providing maximum adhesion without rippling or blistering.

Application(s): Drywall

The OS-300 diamond-punched paper edging allows for easier feathering, faster drying, and the highest bonding strength. Also guarantees an even lay-down of the paper, providing maximum adhesion with no rippling or blistering.  Apply with all-purpose joint-compound.

  • Vertical or horizontal outside 90° corners
  • Clean installation
  • Composite backing provides a tough, durable corner with no rust
  • Nose resists dents and ensures perfect corners without paper fuzz-up during finishing and sanding

Installation

  • Cut OS-300 to measured length. For vertical corners, cut 1/4” short of floor.
  • Apply all-purpose joint compound with Mud-Pro2 (compound applicator) to corner bead; or apply compound to outside corners with a 5” or 6” taping knife.
  • Press corner bead into wet compound by hand or use Strait-Flex’s OS-300 Rolling Tool for fastest results.
  • Adjust if necessary to create a straight line.
  • Wipe down edges and let dry. Apply final coat, let dry, and sand.
