The aim of the work was the assessment of caffeine as an anti-mold additive in a commercial wood preservative containing copper for pressure impregnation. The wood preservative was enriched with caffeine of five different concentrations (1%, 0.5%, 0.25%, 0.125% and 0.0625%). Four microfungi A. niger, P. funiculosum, P. variotii and T. viride were used in the mycological test. It was found that the mixture of wood preservative and 1% caffeine protects until the 7th day to an extent satisfactory for wood against mold growth.
