Anti-slip surfaces are formed (Figure 1) by distributing aluminium-oxide particles 3 over a first coat 2 of an alkyd or epoxy-resin paint containing chlorinated rubber, while the paint is still wet. A second coat 4 of the paint is sprayed over the first coat 2 to lock the particles 3 in. The surface can be given retro-reflectivity (Figure 2) by distributing glass beads 10 over the second coat 9 before it dries, such that the beads 10 nestle between the particles 8 and sink partially into the second coat 9. The anti-slip system may be used on a two-ply glass-fibre tile (Figure 5). <IMAGE> |
