Mixing & Application
Mix ratio by weight : 2.5 parts Castmonite Powder to 1 part Castmonite Liquid acrylic.(e.g. 200g powder with 80g liquid) Add powder to liquid and mix both parts until a lump-free uniform consistency is achieved. Mixing thoroughly is the key for a smooth silky finish, ensure that the sides and bottom are scraped and incorporated into the mixture. Mixing can either be by hand with stick, spatula or similar, or with an electronic mixer. Add colour pigments to the mixture as needed. Immediately pour into the mould and agitate to level the mixture and clear trapped air bubbles. If it thickens rapidly whilst pouring, simply stir again and it will return to its original state. Allow mixture to harden in 10-30 mins. Demould in a couple of hours is recommended, extra care needs to be taken when demoulding product within an hour as product can be fragile within this time frame. 7 days to reach maximum strength.

Note: Castmonite product is designed for single pour only. The mixture will start to thicken immediately after stop mixing. Pour immediately into the mould for best result. For multiple pours, you would need to use Castmonite Slowing Agent to extend the pot life. Take extra care when demoulding product within an hour. Product can be fragile within this timeframe.
