To use Mikrosil^®, simply mix the putty and catalyst on a mixing card with the supplied spatula and apply it to the surface being cast. Within six to eight minutes, the cast will be set. Mikrosil^® even works in below freezing temperatures, creating a perfect cast within fifteen minutes!

Mikrosil^® is available in four colors:

Brown is the color which many tool mark examiners prefer. The dark color increases the visibility of detail in the casts made from tool marks, firing pin marks, breech face marks, and other marks on cartridge casings.
Gray is preferred by other tool mark examiners who photograph the contrast between the light-colored surface and shadows produced from side-lighting.
White or Black can be used to lift dusted latent fingerprints from rough or textured surfaces where regular lift tape will fail. Use white Mikrosil^® with black powders and use black Mikrosil^® with white, silver, or fluorescent powders.
