3M Scotch-weld 7100148747 Polyurethane Adhesive 48.5ml

Product Description

The 3M SCOTCH-WELD 7100148747 is a polyurethane construction adhesive packaged in a 48.5 mL cartridge. It bonds concrete, masonry, and stone surfaces in structural and repair applications. The gray color blends naturally with most masonry substrates. Polyurethane chemistry delivers a flexible, durable bond that resists vibration and minor movement after cure. Full cure is achieved in approximately 1 hour, allowing work to resume quickly on the job. This adhesive is installed by general contractors, tile setters, masonry tradespeople, and experienced DIYers working with hard substrate materials.

This adhesive is suited for residential and light commercial construction and repair work. Typical applications include bonding concrete to concrete, securing masonry units, and adhering natural stone in structural or decorative installations. The cartridge format is designed for use with a standard dual-component or single-component dispensing gun depending on cartridge configuration, giving the installer controlled bead placement on vertical or horizontal surfaces. It is particularly useful in situations where a flexible bond line is preferred over rigid epoxy chemistry.

Installation Notes

Surface preparation is critical — substrates should be clean, dry, and free of dust, oil, and loose material before applying adhesive. Dispense using an appropriate cartridge gun and apply consistent bead pressure for uniform coverage. Follow local building codes and adhesive manufacturer guidelines for structural applications. Allow full cure time before loading or stressing the bond joint.
