The mixture had the consistency of a thick paste or putty. It was applied to the vehicle, usually at the factory, patterned, and then hardened with blow torches. There were many variations seen in application designs, from the regular ridge-shaped pattern, to a less common waffle-shaped pattern.

In general, vehicles already in service were not coated with Zimmerit.
