METHOD FOR CLEANING FACES AND INTERNAL ROOMS OF BUILDINGS AND OTHER STRUCTURES MADE OF CONSTRUCTION MATERIALS FROM VARIOUS CONTAMINATIONS AND BLOOMS Russian patent published in 2007 - IPC B08B3/02 

FIELD: treatment of surfaces, in particular, cleaning of faces, building entry vestibules and stair enclosures, other internal rooms and engineering constructions and architectural parts of buildings under construction, reconstruction and repair from various kinds of contaminations and blooms.

SUBSTANCE: method involves cleaning surface using high-speed flow (300-600 m/s), said surface being preliminarily cleaned using air-water stream having content of water component 0.001-0.01 of volumetric part into which potassium ferricyanide is introduced in an amount of 0.5-10 wt% and polyvinyl alcohol in an amount of 0.1-0.2 wt%; performing cleaning and simultaneously preserving surface against blooms using high-speed stream of water suspension containing finely dispersed (up to 100 micron) particles of clayish raw materials with concentration of clayish phase in suspension making 20-45 wt% and calcium bicarbonate used in an amount of 1-3 wt%; drying treated surface using high-speed air flow having temperature of 15-50 C.

EFFECT: increased efficiency in cleaning of building surfaces and prolonged repair-free time, as well as provision for mechanization and automation of cleaning process.
