“…After drying as detailed above, the specimens were reconditioned at 208C and 65% RH and then put outside on a rack with an inclination of 458 and facing south-southwest (EN 927-3; European Committee for Standardization 1996b), at the field test site of Ghent University (Belgium). The general appearance of organosilicon treated Scots pine samples is evaluated based on these specimens (De Vetter et al 2009c). After 3 years natural weathering, the specimens were removed from the rack and reconditioned prior to contact angle measurements.…”

The interaction of wood with water is a primary factor for degradation of the substrate. Organosilicons are known to behave like a water repellent, thus they are in discussion as protecting agents for wood used outdoors. In the present paper, the influence of water on organosilicon treated material was investigated. Solid Scots pine sapwood was impregnated or treated superficially with low concentrations of organosilicons and evaluated for several water related characteristics. The results confirm the water repellent properties of organosilicons as the polysiloxane film increases the contact angle between water and the wood substrate. However, they do not influence the total uptake of moisture but can change the rate at which moisture is taken up, and as such, prolong the service life of the substrate. In general, impregnated specimens behave better than dipped ones. To gain more insight in the exact behavior, continuous moisture uptake experiments are needed in real outdoor exposure tests.

Consolidation of frail, degraded wood is a key issue of wooden cultural heritage conservation. Paraloid B72 is one of the most often used consolidant in conservation practice. The present research aimed at formulating stable consolidation solutions of Paraloid B72 with ZnO nano-additives and at determining the influence of these additives on the penetration pathways, retention of the consolidation material into wood and on the water behavior of the treated wood. The experiments were performed on sound samples of aspen (Populus tremula). The addition of nano-ZnO slightly increased the uptake and retention of the consolidant within the wooden structure and led to hydrophobic surfaces. However, the influence of nano-ZnO additives to the water absorption was not conclusive. Scanning Electron Microscope coupled with an EDX Detector investigation proved vessels, fibers, and interconnecting pits as main pathways of consolidant penetration into the wooden structure as well as the presence and distribution of nano-ZnO.
