Gypsnow is a powdered gypsum plaster that slightly expands with the addition of water.  Gypsnow is shaped by utilization in molds and may also be carved, cut or shaped after being removed from a mold and a short drying period (about one-hour.)  Gypsnow remains 'soft' and is often used for special effect props requiring physical impact.

50lb / 22.67 kg bag


Molds to any shape
Excellent for 'impact' props
May be tinted or painted

The following quantities of Gypsnow and water will expand to just over the top of a 5-gallon pail:
14 ¼ pounds (6.5kg) Gypsnow  + 1.4 gallons (5.29 liters) water

Do to the expansion of Gypsnow, the maximum recommended mix for any one pour is 5-gallons.  Add the required water to a 5-gallon pail.  As soon as the Gypsnow powder is added - mix immediately for 3 to 5 seconds with a low speed paddle type mixing blade.  Pour as quickly as possible into the mold.

For additional strength Structolite plaster from United States Gypsum may be added.  Structolite shall be added to the water before the Gypsnow.  Structolite shall not exceed 30% of the weight of the Gypsnow being mixed.  The use of Structolite will reduce the rise of the Gypsnow in a 5-gallon pail by 2” to 3”.

Drying / Curing:
Gypsnow must stay in the mold for 45 minutes to an hour before the product may be removed. Cutting, carving and painting may take place when the product is removed from the mold properly dried.

Gypsnow shall be kept indoors or if stored outdoors, shall be adequately covered to keep dry and be stored off the ground.
