Preparation

Clean and dry the rubber crumb.
Clean the mold from dirt.
Apply anti-adhesive grease.

Application

Load the rubber crumb into a mixer (rotary or screw), add some dye (if necessary). Stir for 10 minutes to break up lumps and mix the pigment.
Add Himtrust PU-Adhesive cold pressing (1K) in the amount of 22% of the mass of the rubber crumb. Stir for at least 5 minutes.
Spread the mixture evenly over the molds using spatulas.
Dry the molds in a chamber with high humidity and a temperature of 40-60ºC. The time to dry is 4-6 hours. To speed up the process of drying, you can add water in the glue and crumbs mixture with up to 1.5% of the mass of the mixture.
Once mixture is dry, the tools should be cleaned with organic solvents (acetone, xylene). Dried glue can be removed from the tools mechanically.
