FIELD: chemistry.
SUBSTANCE: method of producing non-skid floor coatings includes treating the surface of coatings with an aqueous composition containing, wt %: ammonium bifluoride 1-4.5, sulphuric acid 2-8, oxamine 0.10-0.15, water - the balance. Said composition can further contain ethylene glycol or propylene glycol in amount of 15-23 wt %.
EFFECT: treating a floor surface at subzero temperatures of up to minus 21 degrees while simplifying and reducing the cost of the treatment method.
