The Stucco Patch-Tie is a stainless steel helical shaped Stitch-Tie Anchor and is used to provide a non-corrosive mechanical connection between a back-up material and stucco as a means to key the patch material mechanically to the parent structure.
Stucco is an exterior surface treatment of buildings consisting of Portland cement plaster. Typically applied on masonry or building surfaces in thicknesses 5/8” to 1-1/2” thick. Delamination of the stucco can occur if the original construction connection has been compromised. Re-anchoring existing stucco veneer can be accomplished with 8mm x 3” or 4“ Stucco Tie helical anchors. Installed in a 3/16” pilot hole provides a threaded connection of the existing stucco and back-up masonry. The anchor is 304 SS and can be produced in 316 SS if additional corrosion protection is required. The pilot hole should be drilled at an angle, 30° – 45°, for optimum anchor engagement. However 90° to the face installations are possible in some instances.
