Ultracal 30 Mold Making Gypsum - 20 lbs. (You will receive 2 - 10lb bags)

Ultracal 30 is a super strength cement that works great for projects where accuracy and greater surface hardness are required. This can be used with latex molds, and works great for projects such as lawn ornaments and mold making.
When mixing Ultracal 30, always add the powder to the water slowly, letting the powder absorb the water. When the water has been absorbed, the surface will look like a dry river bed. Mix thoroughly to break up any lumps. The ratio for mixing Ultracal 30 to water is 3:1. Approximate working time is 30 minutes.
