Acrylic Sand and Dirt Hardener is a fast drying, clear acrylic spray created to stabilize footprints and tire tracks found in sand and dirt. TRITECHFORENSICS' Acrylic Sand and Dirt Hardener can be used with plaster, dental stone, and silicone rubber casting material. Once dried, the hardener helps prevent the distortion of the impression from the weight of the casting material.
