3M Scotch-weld 7100148740 Polyurethane Adhesive 48.5ml

Product Description

The 3M SCOTCH-WELD 7100148740 is a polyurethane construction adhesive packaged in a 48.5 mL cartridge, formulated for bonding concrete, masonry, and stone substrates. It delivers a full cure in 1 hour, making it well suited for time-sensitive repair and installation work. The gray color blends naturally with most concrete and masonry surfaces. This adhesive is typically installed by general contractors, tile setters, masons, and maintenance technicians working on structural or surface-bonding applications where a durable, moisture-resistant polyurethane chemistry is required.

This product is designed for use on horizontal and vertical concrete, masonry, and natural stone surfaces in both residential and commercial settings. Common applications include setting stone veneer, bonding masonry units, repairing concrete joints, and anchoring structural elements to masonry substrates. The cartridge format is compatible with standard dual-cartridge dispensing guns, allowing for controlled, consistent bead application in the field or on the job site.

Installation Notes

Surface preparation is critical — both substrates should be clean, dry, and free of dust, oil, and loose material before application. Use a compatible cartridge dispensing gun and purge the nozzle until adhesive flows evenly before applying a bead. Follow local building codes and the adhesive manufacturer guidelines for joint design, open time, and load-bearing applications. Allow full cure time before applying stress to the bond.
