Introduction

For footwear impressions or tire tracks in the snow, it is recommended that prior to casting, Snow Print Wax™ be sprayed into the impression. Snow Print Wax™ "holds" the details of the impression. Because the substance is waxy, it insulates the snow and prevents loss of footwear or tire track detail from the exothermic (heat producing) reaction of the hardening dental stone casting material.

Application

The application process is easy. Spray a few layers of Snow Print Wax™ in the impression, allowing each layer to dry for just a moment before adding another one.

Gently pour the prepared dental stone impression material onto the Snow Print Wax™ and allow it to harden. In the photographs, we are using a plastic bag to mix and pour the dental stone, so we can discard the bag when finished.

Perform the other procedures as you normally would, at this point. If you add sticks to improve structural integrity, do so. If you scratch in the date, case number and your initials, do so.

When the dental stone is cool and hard, carefully remove it from the impression in the snow. The Snow Print Wax™ will adhere to the hardened dental stone casting material. The red color makes photography of the details in the dental stone easier than a totally white cast.

Since Snow Print Wax™ is red, spraying several layers on the impression allows for the superior photographic recording of the details in color before casting. Also, it is a good warning sign to other persons at the crime scene, so they won't step on the impressions or drive their vehicles over the suspect tire tracks.

One can of Snow Print Wax™ should do 7-10 prints, depending on the size of the impression
