Gypsnow is a powdered gypsum plaster that's terrific for faking objects—concrete, cinder blocks, bricks—that are lightweight, fragile, and will be destroyed on camera. The light weight and fraility of cured Gypsnow make it exceptionally safe to destroy around talent and crew.

Able to be molded into any shape, once hardened Gypsnow is easy to carve, cut, or shape.

It's also frequently used to build miniatures that will be destroyed on camera and to simulate impact effects.

Sold in fifty (50) pound bags.


Gypsnow expands rapidly with the addition of water. Gypsnow molds to any shape and may be carved, cut, or shaped.

Due to the rapid expansion of Gypsnow, the maximum recommended mix for any one pour is five (5) gallons.

The following quantities of Gypsnow and water will expand to just over the top of a five (5) gallon pail:

9 lbs Gypsnow + 1.3 gallons water. Use warm NOT hot water.

Always use a release agent such as Murphy's Oil Soap in your mold or bucket.


Start with the required water in a five (5) gallon pail.

Add all of the Gypsnow powder at one time and mix immediately for 3 to 5 seconds with a low speed paddle type mixing blade.

*Do not over mix.

*Pour as quickly as possible into the mold.


Gypsnow must stay in the mold for forty-five (45) minutes to an hour before the product may be removed.

The product must be allowed to dry for at least forty-eight (48) hours before it is cut, carved, and/or painted.


Gypsnow should be kept indoors where possible. If stored outdoors, ensure product is on a pallet off the ground and adequately covered to remain dry.
