Insulation Anchor and Hanger Adhesives are water resistant, thermal shock resistant, and have an uncompromised level of strength. However, their effectiveness depends on proper use. By following these guidelines, you will get the most out of this heavy duty, industrial strength product.
- SURFACE PREPARATION. Surfaces that are to be bonded need to be clean, dry, and free of contaminants. This includes dust, frost, wax, oil, moisture, dirt, grease, and rust. Do not use over painted surfaces, and remember that many protective coatings are not compatible with anchor adhesive. New concrete surfaces need to cure for 28 days minimum for best adhesion, and all concrete surfaces should be water or sand blasted to remove foreign matter and surface curing agents. Remember to check the quality of the surface where adhesion is applied; loose or unstable surfaces will compromise the strength of the adhesive bond.
- TEMPERATURE PREPARATION. Adhesive should be stored at room temperature (60ºF to 80ºF) for at least 24 hours prior to use. While working, the adhesive and materials to be bonded should be between 30ºF to 120ºF. Do not apply at temperatures below 30ºF. It is recommended to maintain these surface and air temperature guidelines for the first 72 hours after application, or “curing period,” to allow proper setup and cure of material.
- ANCHOR INSTALLATION METHOD. Prepare and install one insulation anchor at a time. Apply a dab (about the size of a small walnut) of adhesive to the base with a putty knife and press the anchor firmly into place immediately using a slight twisting motion (maximum open time is 10 minutes). After the anchor has been firmly pressed into place, ensure that a film of adhesive covering the anchor base is protruding through the Anchor perforations. If “fingers” of glue do not protrude through the perforations in the anchor base, the anchoring may not hold.
By applying these simple rules, you will help create the optimal bonding, strength and benefits from this high-hold, heavy-bodied specialty adhesive.
