hydroflow Sealer 200ml

hydroflow Sealer is an acrylic coating for our hydroflow Water Based Casting Compound

Spray onto casting once dry to increase stability of substrate and to prevent staining. Two thin coats are recommended, additional coats will help reduce water penetration.



Ensure all surfaces are clean and dry. Apply hydroflow Sealer to your fully dried hydroflow casting, work into the surface with a brush or cloth to completely seal the surface and do not allow to pool. 


Allow 2-3 hours between coats. Fully dry in 12-18 hours.
