This research presents the result of studying self-cleaning effect of surfaces used for external coating of residential and industrial buildings. Methods of obtaining above-mentioned effect are examined, including photocatalytic and hydrophobization methods. Widely known methods for determining the wetting angle are applied. Low temperature unbalanced plasma generator is used to modify fine filler material. Wetting angles obtained by using various formulas for water repellent suspensions are observed. Quartz filler material is also modified. The experiments confirms technical effectiveness of water repellents and the enhancement of their properties, when using dispersed fillers. High values of wetting angle are achieved using plasma-modified aggregate.
