SURFACE-SPRAYING DEVICE A device designed for spraying surfaces to be used to coat outer surfaces of buildings, engineering, road and similar structures with sulphur polymer-based agents, is the object of an invention.

Sulphur polymer has been used to a limited extend *** for proofing materials *** so far, which has been described in Patent XXX . According to this invention, *** the procedure of proofing materials *** with sulphur polymer consist in heating, preferably with microwaves, of a material to be proofed, at least on a surface to be proofed, to a temperature between 100°C and 270°C, and then coating *** the surface to be proofed *** with sulphur polymer saturated preferably in a carbon dioxide atmosphere, where sulphur polymer occurs in the form of powder and/or liquid and/or emulsion amounting to 0.03-0. 7 kg/m2, or *** material to be proofed*** is immersed in liquid sulphur polymer saturated preferably in a carbon dioxide atmosphere, heated to a temperature between 120°C and 140°C and for a time between 1 s and 20 s, and then sulphur polymer impact on the material to be proofed is stopped by heating it additionally to a temperature up to 350°C until proofed surface dries and cools to ambient temperature.

The purpose of the invention is to develop a mobile device designed to make coats using sulphur polymer-based agents which function is *** to proof and seal *** coated surfaces making them protected against weather impacts. The device can also be used as a batch feeder of sulphur polymer for reeling aggregates in mixing plants.
