> Creates a casting impression of a shoe print in the snow
A shoe print in the snow is difficult to see the pattern of the impression. Here we have a suspected shoe for a casting of a snow impression. The casting was made from a week-old snow impression, at -15C° The technique works best on wet melting snow but also provides adequate results on cold frozen snow.
Lifting the impression can be easily done. First you need to sift over the shoe print. Put a thin layer of dry Snow Print Plaster powder on the impression that if you don’t, you won’t get a good result.
The powder will stack neatly on top of the surface of the impression.
Immediately after sifting, start mixing plaster. Mix the mixture with water according to the instructions on the bucket.
Mixing using a spoon and stir until the mixture starts thickening (45–60 sec)
When the mixture starts to set, pour directly into the impression, working time approx. 30 sec. At low temperature, cover the poured plaster with newspaper. The cast can be lifted after 8–10 minutes.
Look what a difference. You can see the impression clearly and now the shoe print is secured.
You can see individual marks in the sole correspond to details in the plaster casting.
