Reinforcement for inside or outside corners

Cornerite™ reinforcing angle is used to reinforce all inside or inner plaster corners to reduce corner cracking. Cornerite reinforcing angle is formed from finished, edge strip lath and bent lengthwise to a 100° angle ensuring a snug fit into 90° inside corners and over 90° outside corners.

Application(s): Stucco

Cornerite™ is commonly used where walls meet walls or ceilings, over inner angles of masonry construction, and when using the floating-angle-method of applying gypsum lath to wood framing in order to reduce plaster cracking.

Cornerite reinforcing angle should be tied to the base lath using 18-gauge tie wire. It should not be attached directly to the support framing but allowed to float in the corner.  Available in 2" x 2" (4' and 8' lengths), and 3" x 3" (8' length only).

Galvanized steel products should not be used with magnesium oxychloride cement stucco or Portland cement stucco containing calcium chloride additives.
