Abstract
A coating having a thickness between 0.1 and 2 mm is obtained from a mixture with the following composition: 10-25% by weight of micronized powder; 40-60% by weight of inorganic gravels of petrographic origin of sizes between 0.063-2 mm; 10-40% by weight of a polymerisable base resin selected from polyurethane, polyester, epoxy or acrylic, with additives, and optionally pigments. The proportion of the mentioned gravel and micronized powder of the coating being up to 90% in an inner most area of interphase between coating and surface of the petrous substrate, covering one third of the thickness of the coating.
