The contractor is best qualified to determine the waste factor. ***The amount of Pro Catalyst added to Parapro and Pro Resins is based on the weight and associated volume of the resin used, and varies with the ambient temperature and type of resin. The amount of Pro Catalyst added to Parapro and Pro Resins must never be less than 2%. If resin mixed with the minimum required catalyst of 2% does not have sufficient pot life, the ambient temperature is too high. Refer to Pro Catalyst mixing charts on the back of this guide for more information.
