CrystalGel is a non-toxic, water-based material which provides a clear, plastic-like coating on virtually any surface used in modern stagecraft. It air dries quickly - usually within hours - to a flexible, translucent surface. When dry, it can be painted with any Rosco Scenic Paint, or carved, or safely rolled without cracking, peeling, or sticking. Such products as sand, sawdust or powdered clay can be added to it to create unique textures. Paint, dye, glitter, mica powders may also be added to CrystalGel and then applied to a substrate.

CrystalGel is a styrene resin, providing the greatest adhesion power of any non-oil based product. Among the soft surfaces to which CrystalGel will adhere are styrofoam, ethafoam and, of course, muslin and fabrics. Among the more rigid surfaces to which CrystalGel will adhere are metals, glass, plastics, wood, Luan and fiberboard. It is particularly effective in adhering to plexiglass without cracking or falling off.

You can apply CrystalGel to a 2 x 4 with a tool as simple as a plastic spoon. The material will hold an edge without melting.

CrystalGel will adhere to a number of materials used in stagecraft. Some examples, shown here, are upholstery foam, polystyrene, pine, aluminum, ethafoam road and steel.

Many scenic artists will use a cake decorating tool for applying CrystalGel. It's shown here being applied to aluminum.

You can use a pastry tube to apply CrystalGel, especially when using it as an adhesive for attaching beading. You can add dye to CrystalGel to create decorative details. That is also most easily accomplished with a pastry tube.

You can use a chip brush to apply CrystalGel to plexiglass. Rosco added leather dye to the CrystalGel to help create a stained glass or textured glass effect.

Drying Time:
Varies with thickness of coating, but usually dries to the touch between one and eight hours. Allow 24 hours for complete cure.
Varies with application method, tool and substrate; approximately 250 sq. ft. per gallon (23 sq. m. per 3.79L).
Easy clean up with soap and water. NOTE: Be sure to clean before CrystalGel completely dries. Once dried, clean up is difficult.
Apply by brush, roller, pastry tube, trowel, tongue depressor or other tool. CrystalGel has the consistency of hair gel. It may be thinned with water for a more liquid consistency. But the binder strength may be compromised if thinned more than 10%.
Surface Preparation:
All surfaces should be clean, dry, dust and grease free before application.
Shelf Life:
Minimum 12 months
Do not apply when surface or air temp is below 50°F (10°C). CrystalGel will freeze and become unusable at temps below 32°F (0°C), used or unused. Do not take internally. Use with adequate ventilation. Keep out of the reach of children.

Same Day Shipping Cutoff time

Online orders received by noon Eastern time typically ship the same day. If your delivery due date is critical please note your due date in the order messages at checkout, and then contact us.

Why Noon? Well, while we stock quite a few items in our warehouse, many items we have dropshipped by our vendors. They need time to process the order, so to ensure that we can get the order to the vendor and give them enough time to ship it out the same day, we need to get the order to them as early as possible in the day.

Shipping Rating

Please also note that the shipping rates for many items we sell are weight and dimension based, as this is the method that FedEx and UPS use to rate the package's cost to ship.

Returns Policy

We understand things happen and items occasionally need to be returned. To make things as hassle-free as possible, we have dedicated pages about our Returns Policy (what’s eligible to be returned) and our Return Process (how to go about returning eligible items)
