Casting shoeprints

 

Foot- and tireprint casting kit


This Footprint Investigation kit has been especially composed for the fixing and casting of tire- and footprints found in sand and mud. Apart from the usual tools and plaster, the kit is provided with a special fixative in aerosol form for fixing the surface of the impresssions. A release agent is included to facilitate loosening of the casted imprint. A photo ruler, clearly readable against all surfaces, is an important aid in photographing the impression

Plaster of Paris

Plaster of Paris for shoe impressions, white, extra hard. Package of either 800 or1000 g in a polyethylene mixing bag. The mixing bag is additonally stored in a pouch made of laminate material for prolonged storage (preventing the plaster of attracking moisture).

Unifix 16

Unifix will penetrate the porous structure of soil and sand to fix them, moist or not. The surface of the impression will be sealed and impenetrable for the plaster after preparation with Unifix.

Unifix is used for preparing shoe impressions in loose soil before casting with plaster of Paris.
Unifix will penetrate the porous structure of soil and sand to fix them, moist or not. The surface of the impression will be sealed and impenetrable for the plaster after preparation with Unifix. The result will be a cast with better details and less adhering soil.
 
If the soil with the impression is very loose like pure sand (on the beach or in the dunes for example) it is best to first make the impression slightly humid by spraying a fine mist of water over it (spraying horizontally) so that the water droplets drift to the surface by gravity. Then proceed with spraying with Unifix.
 
To not disturb the impression the aerosol can should be kept at a distance of 25 to 30 cm and moved in a zigzag pattern while going from one end of the impression to the other. To prevent caving in of the impression it is best to start fixing with the outside of the shoe impression.
 
It is best to spray "wet on wet" when fixing with Unifix - so not let the layers dry in between subsquent sprayings. Drying of the Unifix will be faster when the temperature is higher and airflow (wind) stronger.
 
As a last step before the pouring of the plaster a treatment with silicone spray (SLM) can be done. This will further prevent soil particles from adhering to the cast.

Mixing bowl/sieve

To mix plaster with water a plaster-mixing bowl is useful. When the bowl cannot be cleaned immediatly, the plaster can be broken loose from the bowl once the plaster has hardened, by kneading/deforming the rubber bowl (1.9 liter when filled to the rim).
To avoid lumps in the plaster a sieve can be used when the plaster powder is transfered to the mixing bowl.
Also used when underwater-casting a shoe impression in very shallow water (like puddles.)

Contrast powder for impressions in snow

Latent Black and Latent Silver were originally developed for developing fingerprints. The powder is applied to the surface from an aerosol spray can. The same powder can also be applied to a shoe or tire impression in snow. The powder helps to improve the contrast of the impression.
