Techinical Information
Nuflex 456 Heavy Duty Construction Adhesive

Nuflex 456 Heavy Duty Construction Adhesive is a versatile adhesive that exceeds the APAP’s AFG-01 specification. It is designed for awide range of construction applications including wet, frozen and treated lumber. It is also ideal for metal, brick, concrete, ceramics and most large panel-type substrates. Nuflex 456 Heavy Duty fills gaps and irregularities between materials and provides a more solid backup surface. It reduces the amount of nailing and helps eliminate squeaky floors. It also offers excellent water- resistance and remains permanently flexible.

Extremely versatile – bonds most common building materials.

Working Time: Approx. 20-30 minutes for a 1/4” bead. Working surfaces to be bonded should be clean, dry and free from excessive oil, grease, water, dirt or any other material that may deter adhesion. Apply Nuflex 456 Heavy Duty Construction Adhesive to only one of the surfaces to be bonded. NOTE: When bonding subfloors or wet, frozen and treated lumber, nail or screw as recommended by the American Plywood Association. Clean up: Scrape off dried excess with a putty knife. Remove residue with mineral spirits or equivalent solvent. Follow solvent vendor’s precautions when using solvents. Note: Test solvent on an out-of-the-way area to make sure it will not mar or attack the surface. Limitations: Nuflex 456 Heavy Duty Construction Adhesive is not designed for continuous submersion or for use on polystyrene or polystyrene foams. For polystyrene foam, tub surrounds and most other plastics, we recommend Nuflex 454 Multi-Purpose Adhesive.
