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® OM Board Adhesive WG.
Application Methods / Tools
SpotShot Applicator – Cartridges:
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 the adhesive directly to the substrate using a ribbon pattern. Space 19 - 25 mm (¾ - 1 in) wide wet beads at a maximum of 300 mm (12 in) o.c. to achieve proper coverage rate. Actual ribbon spacing will depend on the wind uplift rating required. Allow the adhesive to turn to a pink color (approximately 4 - 8 minutes) before placing the boards into the adhesive. Walk boards in, ballast if necessary to achieve proper contact with substrate.
Adhesive open time varies depending on weather conditions.
PaceCart 3 Installation – Box Sets:
Install Part A and Part B components following instructions on the packaging. Always insure that the Part A and Part B containers are always hooked to the same dispensing holders or hoses (i.e. do not reverse the dispenser holders and hoses between Part A and Part B). All valves on the dispensing unit must be completely opened so a 1:1 ratio is achieved when moving the adhesive through the disposable mix tip and onto the substrate in a semi-liquid state. When starting a new box set, dispense some adhesive into a bucket or other suitable receptacle to achieve a proper mix. Apply the adhesive directly to the substrate using a ribbon pattern. Space 19 - 25 mm (¾ - 1 in) wide wet beads at a maximum of 300 mm (12 in) o.c. to achieve proper coverage rate. Actual ribbon spacing will depend on the wind uplift rating required.
Allow the adhesive to turn to a pink color (approximately 4 - 8 minutes) before placing the boards into the adhesive. Walk boards in, ballast if necessary to achieve proper contact with substrate. Adhesive open time varies depending on weather conditions.
Coverage
Typical coverage rates when using the:
- 1.5 L cartridge: approx.: 56 m² (600 ft²) per case
- 37.8 L box set: 167 to 185 m² (1,500 to 2,000 ft²))
Note: Application rates vary depending on surface roughness and absorption rate of the substrate. Rates are based on an application pattern of 4 ribbons, 19 - 25 mm (¾ - 1 in) beads, 300 mm (12 in) o.c. per 1.2 x 1.2 m (4 x 4 ft) insulation board.
