This study is focused on the development of effective antimicrobial surface treatment of wooden furniture and materials based on wood. The research was performed with acrylic dispersed water-borne and two-component acryl-urethane varnishes. Treatment of varnishes based on chlorhexidine, phthalocyanines and plant extracts and the effect of unfinished wood itself were tested for assessment of antimicrobial activity. The assessment of how safe water-borne varnishes which contain biocides for in-can preservation actually are, was also evaluated in the scope of this thesis. Testing of the antimicrobial efficacy was performed according to a standard routine method and the European and Japanese standards (Agar diffusion plate test, JIS Z 2801 and EN 15457). In addition, a new method testing the antibacterial activity under dry conditions simulating the contamination by microorganisms carried on dust particles was developed. Moreover, the method suitable for testing of photocatalytic active substances simulating the real use of products was described. The appearance and physical and mechanical characteristics were tested in the final treatment of varnishes.
