<p>In a method for the application of a foam layer to a surface for the purposes of cleansing and/or disinfecting the surface, a concentrated high-pressure foam spray is sprayed at the surface under treatment from a large distance. An even distribution of the foam over the surface is achieved not as a result of the form of the jet, but rather as a result of the impact on the foam jet on the surface. In order to achieve this effect, the foam is sprayed at a distance of at least 4 meters from the surface, under a pressure of at least 4 bars and in a volume of at least 150 liters per minute at the surface being treated.</p> |
