Our FOAM-LOK™ spray foam adhesive rapidly bonds Styrofoam and other polystyrene (EPS & XPS) materials in four minutes or less. This highly effective adhesive dries to a clear finish and allows you to bond foam to wood, metal, fabric, and many other surfaces. FOAM-LOK™ spray adhesive is both pressure-sensitive and water-resistant, offering maximum flexibility to its users.

Benefits and features:

  • Works like contact cement (apply to one or both sides)
  • Fast setup time (four minutes or less)
  • Covers approximately 100 SF per can
  • The formulation is safe for use with EPS
  • Excellent for hundreds of different situations


Note: Due to variables with the environment, such as humidity, Demand Products recommends that a test always be performed prior to first use to determine the effectiveness this product will have in your application.

Foam-Lok does not degrade the foam. Foam-Lok is a powerful, fast-setting* EPS adhesive formulation used for bonding EPS to EPS. It also works well for adhering EPS to wood, metal, glass, fabric, and countless other substrates. Foam-Lok is available in a convenient 17.25-oz. spray can or a handy, 30 pound bulk tank sprayer or a 5 gallon brushable container. Foam-Lok dispenses a web-like pattern, delivery about 100 sq. feet per 17.25-oz. can or 3,500 sq. feet from the bulk sprayer. The 5 gallon brushable should cover 1605 sq. feet at a 5 mil thickness.


  The solvent base takes only a 4-1/2 minutes* wait after spraying the surface to be bonded before locking action begins. The water based may take for 5-20 minutes* depending on weather conditions. Foam-Lok does not degrade the foam and works great with foam to foam, wood, metal, fabric, and many other surfaces.


* Because weather, humidity, and temperature can adversely affect both adhering times as well as bonding strength, we recommend a test be performed prior to use to determine the effectiveness this product will have in your application.

FOAM-LOK™ will perform as intended - your results could differ if you do not follow the directions. Also, atmospheric conditions, temperature and thickness of application may vary the results. We suggest a trial test with each application to determine acceptable results.
