18 months if stored properly in original unopened, sealed and undamaged packaging.

Store cartridges in a cool, dry location at temperatures between 55°F (13°C) and 85°F (29°C).

Store box sets in a cool, dry location at temperatures between 60°F (16°C) and 80°F (27°C).

Protect from freezing at all times. Keep containers closed. Contamination by moisture or basic compounds can cause dangerous pressure build-up in a closed container.

50 g/L (Part A & B Combined)

Application rates vary depending on surface roughness and absorption rate of the substrate. Typical coverage rates when used on:

• Concrete is up to 2.5 squares per gallon
• Lightweight Concrete is up to 1.7 squares per gallon
• Cementitious Wood Fiber is up to 1.2 squares per gallon
• Gypsum is up to 1.2 squares per gallon
• Mineral Surface Asphalt and other Approved Sika Vapor Retarders is up to 1.7 squares per gallon
• Aged Smooth Asphalt is up to 1.7 squares per gallon
• Polyisocyanurate and Polystyrene Insulation is up to 2.5 squares per gallon

Rates are based on an application pattern of ribbons 12" (30 cm) o.c.

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.

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 Sarnacol® OM Board Adhesive WG directly to the substrate using a ribbon pattern. Space ¾ – 1" (19 – 25 mm) wide wet beads at a maximum of 12" (30 cm) 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 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.
