Notched trowel: Apply adhesive with a 3 mm (1/8 in.) V-notched trowel (recommended method to bond polystyrene panel or gypsum panels to insulation surfaces, see restrictions).
In bead: Apply a 12 mm (1/2 in.) diameter bead at 150 mm (6 in.) between the axles forming a serpentine. In drops: Apply nut-sized drops every 150 mm (6 in.). Once flattened out, the drops will have40 to 50 mm (1 1/2 to 2 in.) diameter. Set the insulation panel in place by firmly pressing in several areas for maximum contacts.
Note: Joints must be seal to prevent air infiltration behind insulation panels. Drying time depends on application method, temperature and surface porosity. |
