This study evaluated some textile auxiliaries applicable for wood protection. Commercial alkoxysilane quarternary ammonium formulation and fluorocarbon based water-oil repellent were tested for their ability to provide hydrophobicity and antifungal effect to solid wood samples. Scots pine (Pinus sylvestris L.) sapwood samples were impregnated with 25, 50 and 100 % concentrations of the above mentioned compounds and cured in an oven at 80 ?C for 24 h. Water absorption rate (WAR), anti-shrink efficiency (ASE) and compression strength parallel to grain of the wood samples were determined. Biological resistance of leached and unleached wood samples against fungal decay was evaluated with a modified soil block test using Postia placenta. Fluorocarbon based water-oil repellent and alkoxysilane quarternary ammonium treated samples demonstrated some improved durability against decay fungi and anti-shrink efficiency compared to the untreated controls. The water uptake of treated wood was significantly reduced, especially after the treatment with alkoxysilane quarternary ammonium. The initial water repellence was well pronounced with the both tested chemicals, but after a longer submersion time (2 weeks), the reduction in water uptake was significantly diminished. No significant decrease of the compression strength parallel to grain of wood samples was monitored. Although the improved durability of wood treated with the tested formulations, the performance is far poorer than that of the commercially available copper-based formulations.
