One of the largest issues with treatment on waterlogged wood is finding a way to remove the water in the wood but keep the water that is part of the material. Preventing cell wall collapse (which causes shrinking, cracking, and further damage) of the waterlogged wood while drying is the largest struggle and main goal of treatment.
Wood decay describes wood in all stages of fungal attack, from the initial invasion of hyphae into the cell walls to the complete destruction of the wood. [10] Wood-inhabiting fungi are most common on timber piles above the water surface since the lack of oxygen below water inhibits fungal growth.
These processes autoclave the treated wood, subjecting it to pressure and heat, along with nitrogen or water vapour to control drying in a staged treatment process ranging from 24 to 48 hours at temperatures of 180 °C to 230 °C depending on timber species. These processes increase the durability, dimensional stability and hardness of the ...
Consolidation can also refer to the treatment of painted wood surfaces. Because of the complicated nature of wood as a material, consolidation of paint on a wooden artifact must be carefully undertaken. As wood expands and contracts with fluctuations in temperature and humidity, damages can occur to paint on the wood's surface.
Wood stabilization limits water absorption into the wood structure, thereby limiting the dimensional changes which arise from moisture exposure. Wood stabilization is a subset of wood preservation processes specifically used by woodworking enthusiasts to alter the material properties of specific wood species for applications within their craft ...
To produce furfurylated wood the following steps are necessary: [10] Storage and mixing of impregnation solution: Approximately 40% furfuryl alcohol, water, polymerization initiators, catalysts, and surfactants are mixed and then poured into a storage tank. Impregnation: The wood is soaked in a pressure vessel in a three-stage process. First, a ...

Successful filling of voids in wood requires the filler to precisely match the colour and grain pattern of the wood around the void, which is difficult to achieve in practice. Furthermore, filled voids do not behave like wood during subsequent finishing steps, and they age differently to wood. Hence, repairs to wood using fillers may noticeable ...
