Dupont 343087 Great Stuff Pro Construction Adhesive

Product Description

The DUPONT 343087 is a 26.5-ounce single-component polyurethane foam construction adhesive designed for heavy-duty bonding in wall and floor applications. It is moisture-cured and low-pressure, producing a flexible bond that resists movement and stress after cure. The flexible polyurethane formulation accommodates minor substrate shifting, making it suited for both subfloor fastening and wall panel installation. Licensed contractors and experienced installers working on residential and light commercial projects will find this product appropriate for structural adhesive applications where rigid bonds would be prone to failure.

This adhesive is intended for construction bonding tasks including subfloor installation, wall panel attachment, and general structural bonding where a flexible, durable connection is required. It is appropriate for use in residential framing, remodeling, and light commercial construction scenarios. The moisture-cure chemistry allows the product to work in typical jobsite humidity conditions without additional activators or mixing steps.

Key Features

• Single-component formula requires no mixing or separate activator
• Moisture-cured chemistry works under typical jobsite humidity conditions
• Low-pressure dispensing for controlled application
• Flexible polyurethane bond accommodates minor substrate movement after cure
• 26.5-ounce container sized for professional single-use and multi-use applications

Compatibility

Designed as a general-purpose construction adhesive for bonding wall panels, subfloor materials, and structural components in residential and light commercial construction applications.

Installation Notes

Application should be performed by a qualified contractor or experienced installer familiar with structural adhesive procedures. Surfaces should be clean, dry, and free of dust, grease, or loose material before applying adhesive. Follow all applicable local building codes for adhesive fastening of structural components.
