Abstract
In the method for applying horizontal markings to road surfaces, a water-thinnable emulsion paint which is acid-coagulable is used and is brought into contact with an acid. This acid is scattered or sprayed onto or into the sprayed paint, the acid being in the form of an aqueous solution, a powder or particles wetted with acid. The method brings about drying within one or a few minutes. Using road-marking vehicles, horizontal markings can thus be put down with virtually no closing-off of the mobile operations site.
