Once opened, expires approximately 3yrs from date of purchase. (The specific date will be provided on the label). If left in the foil bag, that time is at least double.
Please Note: If you are looking to get refills for a specific kit and especially if you are new to life casting, please order from the Step 1 Refill page to be sure you will receive the exact same amount and mixing directions as the kit. Some kits do not use the average mixing proportions listed on this bulk bag.
Yield per 1 lb of Powder: About 9 cups (72 fl.oz. or 2.15L) of material
Average Mix Ratio: 3.5 to 1 (water to powder) by weight [OR about a 1 to 1 ratio by volume if the powder is not compressed or packed when measured]
If purchasing stone to go with this, the following is an estimate: you will need about equal amounts (by weight) for infant castings and double the amounts for adult hands. Other types of castings usually fall somewhere in between. Basic mixing directions included. Note: If you will be mixing more than 1lb at one time, it is best to use a small mechanical (preferably electric) hand mixer of some sort.
