• Water and Weather Resistant
• Great for indoor or outdoor projects
• Bonds to most building materials
• Provides a strong, durable bond to multiple surfaces
• Gap filling
• Will bridge minor gaps when bonding irregular
• High Grab
• Reduces the use of fasteners.

Recommended For:

• Bonding to all types of surfaces: wood, fiberglass panels, concrete, brick and drywall; it permanently joins foamboard to the substrate without compromising the insulation value of the foam.

Not Recommended For:

• Do not apply at temperatures lower than 40°F (5°C) or above 100°F (38°C)
• Not to be used in areas subject to permanent water immersion
• Do not use on polyethylene (PE), polypropylene (PP), polytetrafluoroethylene (PTFE) and acrylic
• Should not be applied outside if rain is expected within 12 hours.

Directions:

Safety Precautions:

• Interior applications require ventilation to the outside during application and cure. Wear gloves. Wash hands after use.

Preparation:

• The temperature of the adhesive, the surfaces and the working area must be between 40°F (5°C) and 100°F (38°C). For smooth, fast, easy application during cold weather, store adhesive at room temperature (70° ± 5°F) 24 hours prior to use. Ensure surfaces to be bonded are clean, dry, structurally sound and free of dust, grease, oil or other contaminants. Pre-fit all materials prior to applying product. Mechanical fasteners must be used and kept in place until adhesive is fully cured. Cut off tip of cartridge at 45° angle to desired bead size and puncture inner seal of cartridge. Recommended bead size is 3/8” (9.5 mm).

Application:

• Using a caulking gun, apply adhesive as a series of horizontal beads 9 to 12 inches apart. Start the beads approximately 1 inch from the panel edge. Within 10 minutes of applying the adhesive place the foam against the substrate and press firmly into place to flatten out the adhesive. Mechanical fasteners must be used and kept in place until the adhesive is fully cured. Cure time will vary depending on the porosity of the material used. Support is recommended until adhesive cures. The adhesive must be fully cured before it can be exposed to elevated temperatures.
• Drywall application over foam insulation: Apply adhesive as outlined above. Position drywall, align and press firmly into place. It is recommended to brace panels in the field for at least 24 hours. Nail panel to underlying studs or strapping around entire perimeter.

Cleanup:

• Clean tools and uncured adhesive residue immediately with water. Cured adhesive may be carefully cut away with a sharp-edged tool.

Additional Info:

• PL® 300 VOC is a latex-based adhesive especially designed for bonding polystyrene foam to itself or to a variety of construction materials, including, but not limited to: wood, gypsum board, concrete and brick. Low VOC formulation meets stringent State and Federal VOC Regulations.
