Clear, flexible, and a primer for surfaces paint won't stick to
CrystalGel is a water-based, non-toxic scenic coating that dries clear, flexible and durable. Use it as a clear protective coat, a primer that helps paint bond to foam and synthetics, or a texture medium for glossy, glass-like, wet and dimensional effects.

Most common CrystalGel projects
- Primer for foam & synthetics when paint won't bond
- Clear protective coat over scenic finishes
- Wet / glossy / glass-like effects (water, slime, ice)
- Binder for glitter, aggregates, fillers and texture mixes
- Fabric stiffening without turning fabric opaque
- Clear barrier / splinter shield on rough wood
Best for — and the alternatives
CrystalGel is best for
- Clear + flexible finishes (no brittle shell)
- Surfaces where paint won't stick
- Building gloss / wet / texture effects
- Controlled build-up with trowel or pastry tube
If you need something else
CrystalGel is clear and flexible. For a hard shell or a bonding coat:
- FoamCoat → rigid foam hard shell
- FlexCoat → flexible coating for soft foam
- FlexBond → adhesive + coating for mixed materials
