Strait-Flex® Medium

finishes INSIDE 90° AND OFF-ANGLE CORNERS

Strait-Flex Medium is a high-performance dyrwall corner bead.

Description

The slotted edge design facilitates superior bond to the drywall substrate, providing clean corners without paper fuzz-up during finishing and sanding. Medium is ideal for bay windows, coffered ceilings, or any inside corner where gaps are present. Apply with all-purpose joint-compound.

  • Twice as fast and twice as strong as conventional paper or mesh tapes
  • Inside corners where small gaps in drywall are present
  • Inside 90° corners where a small fill or minor straightening is required, no back filling needed
  • Great for vertical and wall-to-ceiling inside corners, inside angles of bay windows
Installation

INSTALLATION

  • Cut Medium to desired length and trim ends at 45-degree angles.  Fold Medium in half at center crease with print size facing each other. For inside corners, fold less than desired angle with print side facing out.
  • Apply all-purpose compound to corner. Press Medium into the wet compound, adjust to create a straight line, and wipe down with a taping knife.
  • A second coat can be applied immediately. Let dry completely over several hours or overnight.
  • 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 dry completely over several hours or overnight.
  • Sand lightly with 120 grit sandpaper. Medium will not fuzz-up like paper or mesh tapes.

HELPFUL HINTS

  • Use a stainless steel mud pan to carry and re-mix compound as you work. Keeping your compound smooth and free of air pockets and dried clumps of compound, will deliver a smooth finish.
  • Have a five gallon bucket of water with a durable sponge handy for cleaning tools.
  • When painting, apply a base coat of drywall primer to seal the compound and assure an even paint finish.
