In many cases we want to clean up a wall “painted” by “anonymous artists” or we want to prevent future would-be artists from drawing on our own spaces. There are also many occasions when we would like to make up for any malpractice for protection. As a solution in this area we offer the present proprietary preparation which is a suspension of special waxes and materials. The suspension has the property of being easily spreadable with a brush or a brush, as well as by spraying. The initial film dries easily and leaves an invisible film that has high non-stick properties, which means that either nothing can be written or stuck on, or if any adhesion occurs it will be superficial and can be removed by easy cleaning.
