Nowdays, an emphasis is plased on an antibacterial properties of various products, including floor and coating materials. This work is about an testing of effectivity of the chosen antibacterial agents in the water born and solvent free floor systems which are epoxide or polyurethane based. As first step, the most suitable representative of each floor system was chosen, the silver based agents (respectively silver anion Ag+ based) which should have an antibacterial effect when incorporated into the floor system was chosen. The selected ones are Ag/SiO2, Ag/TiO2, Ag/Al2O3, Ag/ZnO, Ag/BaO, Ag/zeolite, AgI. The necessary was a creating of the test method which has to offer exact and reproducable outputs. At the begining, the method came out from the norms ČSN EN ISO 20645 Squared textiles – Determination of antibacterial activity – Test of diffusion throught the agar plate, ČSN 79 3880 Testing of antimicrobial properties of material and product of boot industry, Antifugal and antibacterial properties. Testing by this way did not bring repriducable outputs. Only the bacterial strains Escherichia coli, Klebsiella pneumoniae and Staphylococcus aureus was used according to the norms. The method of recultivation was used for testing. The process is: an application of the coating on the bottom of the Petri´s dish, curing, appplication of the bacterial solution, cultivation for 24 hours at 37 °C, inoculation onto the agar in the Petri´s dish, cultivation for 24 hours at 37 °C, interpretation of the grow/inhibition of the bacteries. The results offer the overview about the advantages and disadvantages of each antibacterial agent in the chosen systems.
