PROFESSIONAL GRADE
DESCRIPTION Perfect-90º, a paper laminated composite tape from Strait-Flex, is twice as fast and twice as strong
as conventional paper or mesh tapes. Perfect-90º is designed as only way to finish inside 90º corners
in one coat, cutting the finish time in half. The pre-finished laminated center section of Perfect-90º
ensures a clean, sharp corner without the risk of damage from a taping knife, will not shrink, and will
not fuzz up during sanding. The tape’s outer edge features a diamond punch pattern for a superior
bond, faster drying, with no rippling or blistering. Perfect-90º comes in 50’, and 100’ rolls.

DIRECTIONS

corners, cut ends at 45º angles. For inside corners, fold less than desired angle with print side
facing out.
 With a 5”or 6” taping knife, apply a smooth, liberal coat of compound to corner.
 Press PERFECT-90º into the wet compound. Adjust if necessary to create a straight line.
 Wipe down tight with taping knife using a little additional pressure on the outer edges of
PERFECT-90º. Let dry completely several hours or overnight.
 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.
 Sand lightly with 120 grit sandpaper. PERFECT-90º will not fuzz-up like paper or mesh tapes.
