BUCHARD
Butcher is a process that breaks, roughens the surface of the material like an orange peel. It is used in the processing of stone, marble, travertine, granite and concrete surfaces. Like all processes, it can be performed to a greater or lesser degree of density.
It is used mainly on anti-slip flooring. Aesthetic effect for reproduction, medieval finish, as if the stone was cut by hand centuries ago and additionally worked with a steel or abrasive brush gives it a "worn by time" antique look.
