Mixing Instructions:
Pre‑mix epoxy base then mix at ratio 100% by weight to appropriate % of hardener. Mix well by hand or mechanical mixer. Be sure to scrape sides and bottom or transfer to another container for best mix. For best results, de‑air mix at 29 inches of mercury before pouring. Thick pours may be successful in multiple pours, the first being thin to allow air to flow out. Allow one hour between pours.
Storage:
Store at room temperature or below 90F. Keep out of sunlight or away from heat. When handling, please refer to MSDS.
