Aerosol Dust and Dirt Hardener (15 oz Can)
This efficient method for preparing footprints and tire tracks found in loose or sandy soil is newly packaged in aerosol form. The 638CA features a quick-drying, clear acrylic formula that adds superior strength to impressions—lessening the chance of detail damage due to the weight of the casting material. Use it with plaster-of-paris, HARD-CORE, or Shake-N-Cast™ materials. One 15-ounce can of 638CA Dust and Dirt Hardener is enough to make up to 30 full-size adult shoe impression applications.
