Chemical Properties: Oak has a high tannin content which can be released when the timber becomes damp or wet. This can lead to staining in contact with metal or ferrous fixings. It is advisable to protect any surfaces that may come into contact with the board prior to fixing. Staining may be removed using an oxalic acid cleaning agent. Once the tannins have exuded, untreated the timber will weather to a silver grey.
