hydroflow & Aqua Cast Sealer is a water based polyurethane coating for our hydroflow Water Based Casting Compound and Aqua Cast Water Activated Casting Compound.
Spray onto casting once dry to increase stability of substrate and to prevent staining. Three coats are recommended, allow 1-2 hours between coats.
Shake well before use. Ensure all surfaces are clean and dry and apply hydroflow Sealer to your fully dried casting. Work into the surface with a brush or sponge, do not allow to pool.
Allow 1-2 hours between coats, fully dry in 12-18 hours. We recommend at least three coats for optimum protection. New layers may need to be applied periodically dependant on the casting use and situation.
