Outdoor efficacy of additional hydrophobic treatment of weathered wood by siloxane

Popis výsledku v původním jazyce

Recently, the share of the use of untreated wood in exterior applications has been growing due to positive ecological and health impacts. In particular, facade elements, but also terraces, fences, gazebos, and other structures without contact with the ground can be made of untreated wood with moderate or lower natural durability against bio-damage. During exposure, however, there is a high increase in the water soaking into weathered surfaces. In terms of higher temperatures and more permanent precipitation, the risk of damage by wood-destroying fungi, which have a fatal impact on the functionality of wood products, increases significantly. This work is focused on the possibility of additional hydrophobization of weathered wood with siloxanes. In particular, samples of spruce pre-weathered for 3 and 5 years in an exterior exposition according to EN 927-3 were additionally treated by siloxane emulsion. For partial comparison, oak and larch were also weathered for 3 years, and native non-weathered refe
