Control joint used for DEFS applications to relieve stress caused by expansion and contraction and control cracking in large areas of walls and ceilings. The removable tape creates a mask over the expansion slot during installation for a clean finish.
Large perforations allow the base coat mixture to easily flow through and bond to the substrate. Recommended usage is for every 130-140 sq. ft. with no one side being longer than 15ft. Caulk all intersections, butt joints, ends, and corners at the time of installation.
