Application

Application steps

SUBSTRATE PREPARATION

All surfaces must be clean, dry, and free of dirt, grease, oil, or other contaminants or particulates. All concrete surfaces must be cured prior to applying Sarnacol®-2163 Adhesive.

APPLICATION

Use the handheld cartridge applicator. Remove the plastic plugs from the cartridge mixing head. Attach a mixing tip to the threaded mixing head. Place the cartridge into the applicator. When starting a new cartridge, dispense some adhesive into a bucket or other suitable receptacle to achieve a proper mix.

   

Apply Sarnacol®-2163 Adhesive directly to the substrate using a ribbon pattern. Apply adhesive in 6–13 mm (¼ –½ in) wide wet beads. Ribbon spacing will depend on the wind uplift rating required.

    

As adhesive is applied, immediately place boards into wet adhesive. Walk boards in, ballast if necessary to achieve proper contact with substrate.

   

Unused adhesive can be applied at a later date by simply replacing the mixing tip.

    

COVERAGE
Application rates vary depending on surface roughness and absorption rate of the substrate. The typical coverage rate when using 1.5 L cartridges is approximately 56 m2 (600 ft2) per case. Rates are based on an application pattern of four (4) ribbons, 6–13 mm (¼ –½ in) beads, 300 mm (12 in) o.c. per 1.2 m x 1.2 m  (4 ft x 4 ft) insulation board.
