    Summary
    Results on the antimicrobial efficacy of silver nanoparticles in transparent wood coatings for outdoor application are presented. The performance of different hydrophobic, transparent coating systems with and without silver was studied during 2years of natural weathering. In addition, laboratory efficacy tests were carried out on non-weathered and weathered specimens to assess the resistance of the coatings against mold, blue stain and algae. The protective effect of the tested silver containing coatings against common microorganisms was insufficient, even under initial, non-weathered conditions. Reasons for the failure are the inadequate initial silver concentrations below 50ppm in the coatings and the associated insufficient availability of free silver ions on the coating surface.
