Use the curing compound within 12 months from the date of manufacture or before the expiration of the product shelf live, whichever occurs first.
ASTM C309, Type 2, Class B as modified below:
• Total Solids (% by weight of compound): to be used as a reference
• % Reflectance in 72 hours (ASTM E1347): 60 minimum
• Loss of Water, pounds per square foot in 72 hours (ASTM C156): 0.082 maximum
• VOC content (pounds per gallon): 2.90 maximum
• Infrared Spectrum, Vehicle: 100% alpha methylstyrene
The rate of application for testing untextured specimens in 200 square feet per gallon. Type I cement from Lafarge Bath plant in Ontario and Ottawa ASTM graded sand are used in the mortar for testing. The curing compound must be manufactured to:
• Remain sprayable at temperatures above 40F .
• Control sagging, pigmented settling, leveling, and de- emulsification .
• Maintain the specified properties for at least 1 year .
Settlement of pigment must be a thoroughly wetted, soft, mushy mass allowing the complete and easy vertical penetration of paddle. Settled pigment must be easily predisposed, with minimum resistance to the sideways manual motion of the paddle across the bottom of the container, to form a smooth, uniform product of the proper consistency. Do not dilute or alter the curing compound after manufacture. Package the curing compound in clean 275- gallon totes, 55- gallon barrels, or 5- gallon pails, or supply curing compound from a suitable storage tank located at the job site. The containers must comply with 49 CFR 171 -180. Provide 275- gallon totes and 55- gallon barrels with removable lids and airtight fasteners. The 5- gallon pails must be round and have standard full open head and bail. Do not use lids with bungholes. Fill containers in a way that prevents skinning. Line steel containers and lids with a coating that prevents destructive action by the compound or chemical agents in the air space above the compound. The coating must not come off the container or lid as skins. Plastic containers and lids must not react with the curing compound. Label each curing compound container with:
• Manufacturer’s name
• ASTM C 309 classification
• Lot number
• Volume
• Date of manufacture
• Shelf Life 711.2(b) 711.3(h) • Volatile organic compound content
• Warning that curing compound containing pigment must be well stirred before using with no dilution, introduction of air or other foreign substances into the curing compound.
• Precautions concerning the handling and application of curing compound .
