Page 1 of 3
Loctite® PL® 300 Foamboard Construction Adhesive is a latex water-based adhesive formulation for
bonding most foam insulation panels to a variety of porous construction materials, including, but not
limited to: wood, gypsum board, and concrete. It is compatible with all “unfaced” foamboard insulation
products and won’t burn through foam if used as directed. Low VOC formulation meets stringent State
and Federal VOC Regulations.
Loctite® PL® 300 bonds to most types of surfaces including unfaced EPS (expanded polystyrene
foam), XPS (extruded polystyrene foam), and polysio (urethane) foam, rigid polystyrene, wood, concrete,
non-glazed brick and drywall.
▪ One bonding surface must be porous. Will not bond two non-porous substrates
▪ Do not use on polyethylene (PE), polypropylene (PP), polytetrafluoroethylene (PTFE) and
acrylic or glazed bonding surfaces such as ceramic tile
▪ Will not bond to filmed faced foam insulation panels or polyethylene vapor barriers
▪ 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
▪ Should not be applied outside if rain is expected within 24 hours
▪ Do not apply to damp surfaces
▪ Do not use in cold storage units. Not tested for direct or indirect food contact
