  • Certain hard-tanned leather types result in a granular regrind, while the softer leather types become flaky depending on their elementary fiber structure when grinding granular, the thickness of the coating is determined by the greatest expansion of the grains, which in practice is 0.5-4 mm.

  • the covering material is very easy to smooth, even on vertical, dusty glass surfaces. The extraordinarily good adhesion of the covering material is demonstrated by the fact that a circular covering of 6-8 mm thick, 30 cm in diameter, applied by locking onto a vertically arranged PVC foam, does not slip. not even if the film is moved
  • the coating according to the invention is only sensitive to very coarse contaminations of the surface (for example rust), for wall surfaces of average quality it is sufficient to paint the surface beforehand with a dispersion wall paint.
  • the coating according to the invention can also be formed directly on plastered walls or raw concrete surfaces.
  • the coating is permeable to air because of its porous structure, which ensures ventilation of the coated surface.
  • the extraordinarily good adhesion of the coating according to the invention makes it possible to produce coatings from several layers. Since the covering is already 3-4 mm thick and is extremely well insulated against heat and sound (according to our own measurements, it is about 15 cm thick brick wall), an extraordinarily good heat and sound insulation can be achieved by using a multi-layer covering.
