Flex-90º

Description

Flex-90º, a laminated composite corner tape from Strait-Flex, beautifully finishes inside and outside 90º corners. This 2-1/16” tape features a pre-finished surface with a PUR–laminated nose ensuring perfect corners without paper fuzz-up during finishing and sanding. The tape’s outer edge features a diamond punch pattern for a superior bond, faster drying, with no rippling or blistering.


  • Inside and outside 90º corners. 

  • Diamond-punched 94 lb. 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.

  • PUR-laminated nose ensures perfect corners without paper fuzz-up.

  • Inside 90º corners where a large fill is required.

  • Inside corners of bay windows, and intricate off angles.

Installation

PREPARATION

Run your taping knife over the surface of the drywall and remove any high spots. If the knife hits a screw head, set the screw a little deeper. Use a drywall rasp to clean up edges, if needed.

Measure wall height and subtract 1/2”. Measure and cut Flex-90º using a scissors or utility knife.

(1)  Fold Flex-90º in half at center crease with print size facing each other.

(2)  For intersecting corners, cut ends at 45º angles.

(3)  For inside corners, fold less than desired angle with print side facing out.

Properly mix all-purpose compound per manufacturer’s directions. If applying Flex-90º over painted surfaces, add Strait-Flex’s Super-Bond or latex paint to enhance bondability.

STEP ONE

(4) With a 5”or 6” taping knife, apply a smooth, liberal coat of compound to corner.

(5) Press Flex-90º into the wet compound. Adjust if necessary to create a straight line.

(6) Wipe down tight with taping knife using a little additional pressure on the outer edges of Flex-90º. Let dry completely several hours or overnight.

STEP TWO

Use taping knife to detect and remove any high spots or dried clumps of compound.

(7) Apply final coat to perforated edge only. No compound is needed over finished area of tape. It’s ready to paint.

Let dry completely over several hours or overnight.

STEP THREE

(8) Sand lightly with 120 grit sandpaper. Flex-90º 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.
