These stamps are used to realize a Stamped Concrete on a fresh concrete or on an old screed using a stamping overlay.
Before stamping, the fresh concrete must be first coloured with Masters Colour Hardener to strengthen the surface.
After this step and for avoid your skins not stick the concrete, care must be taken to spray them with a Masters Liquid Release or powdered a Masters Antique Release on the entire surface to be printed.
Note that Masters Antique Release creates a second colour and allows to highlight the patterns.
On an old screed, you must used Masters Stamp Overlay.
In this case, Masters Stamp Overlay must be coloured in the mass during the mixing.
