Abstract

A coating system including at least one reactive resin system RH, at least one thixotropic assistant TH selected from the group consisting of urea preparations HZ and fibers FS and at least one inorganic aggregate AZ having a particle size in the range from 0.2 to 3.0 mm. The coating system has a viscosity as measured with a shear rate of 1 s−1 of 9000-100,000 Pas and a viscosity as measured with a shear rate of 100 s−1 of 400-15,000 Pas. The coating system is notable for high surface roughness and for reliable and long-term bonding of the aggregates to the coating with no need for sealing. There is also no need for the coating to be subsequently strewn with aggregates such as sand, for example.
