Instructions for use of Hydroflow Sealer

Shake the bottle well before use and make sure all surfaces are clean and dry. Apply Hydroflow Sealer to a fully cured casting and allow the product to soak in with a sponge.

For optimal protection, we recommend applying at least three coats. Wait 1-2 hours before applying another coat. Depending on the use of the casting, it may be necessary to apply a new coat. The Hydroflow sealer is completely dry after 12-18 hours.
