Installation:
Suggested Tools: Clean rag, foam cleaner, utility knife, gloves, and goggles

• Prior to use, read directions on label
• Shake can vigorously (20-25 times)
• Clean all surfaces with a clean rag and remove loose debris in cavity
• Screw trigger assembly onto can, ensuring a tightly threaded fit
• Pull trigger to dispense foam, controlling extrusion rate with trigger pressure
• When using as an adhesive, bond substrates together immediately and use mechanical fasteners or clamps to guarantee a permanent bond
  • Tack Free: Approx. 5 minutes
  • Cure: 12 to 24 hours
  • Service Temperature: -200° F to 240° F (-128° C to 115° C)
  • Application Temperature: 40° F to 115° F (4° C to 46° C)

Application: Expanding Foam Sealant should be applied in a well-ventilated area, or with respiratory protection. For best results, use Expanding Foam Sealant with sufficient atmospheric humidity. Deep, dry cavities may need to be moistened before application. However, too much wetness will interfere with adhesion. Fill the lowest part of the cavity first. When using Expanding Foam Sealant, fill only 40% with foam since expanding formula expands approximately 2 1/2 times. Expanding Foam Sealant may be applied in cold or hot ambient conditions as long as chemical temperature is maintained. Expanding Foam Sealant will withstand continuous temperatures up to 240° F (115° C). Do not disturb freshly dispensed foam because it will collapse. Expanding Foam Sealant will be tack free in 5 minutes and cures to firm resiliency within 24 hours, depending on moisture and temperature conditions.
Painting: Expanding Foam Sealant may be painted or stained after full cure. NOTE: Outdoor applications must be coated with a paint or stain to protect foam from ultraviolet light exposure.
