Stucco-Tie - Secures Delaminated Stucco

OVERVIEW

The Stucco-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.

Step 1
Drill a 3/16” pilot hole using percussion hammer drill (3-jaw chuck type) through the stucco.

Step 2
Insert the Stucco-Tie into the dry set installation tool mounted on the rotary hammer S.D.S. drill.

Step 3
Drive the Stucco-Tie until the nose of the dry set installation tool is hard against the veneer.

Step 4
The dry set installation tool automatically recesses the Stucco-Tie into the face of the stucco. Patch hole.
