Anti-slip surfaces with retro-reflective characteristic, are obtained by applying to the surface a first coating of paint, distributing particles of mineral or other material on the coating before the coating has dried so that the particles sink partially into the first coating, then applying a second coating of paint over the particles and the first coating to lock the particles into the first coating with the particles projecting from the second coating, and distributing retro-reflective beads on the second coating before the second coating has dried to sink partially into the second coating such as to be bonded thereto and effectively overshadowed by the projecting particles. <IMAGE> |
