FIELD: construction.
SUBSTANCE: invention is intended for development of functional construction board which would attain antialgal and antifungal properties for long time combined with resistance to mechanical impurities, i.e. allowing for easy cleaning off mechanical impurities, after processing coloured face surface of board with composition containing various bactericide preparations. Invention claims composition for application of protective bactericide coating onto construction board, including mixed solvent consisting of water and alcohol, surfactant, colloid silica dispersed in the mixed solvent, and composite bactericide substance including organic and inorganic component. Also invention claims construction board including base, colour coating and bactericide coating, and method of protective bactericide coating application onto construction board, with bactericide coating applied over colour coating and obtained with the use of claimed composition.
EFFECT: high resistance to mechanical impurities, high bactericide properties.
