Evaluation of Weathering of Furfurylated Wood Decks after a ...

In respect to surface cracking, furfurylated radiata pine deck generally showed minor surface cracks, while furfurylated maple deck presented the lowest degree of surface and end splitting. In overall, the furfurylated wood decks tested performed very well and showed no signs of black staining (except for the southern yellow pine deck)

Weathering of Wood Chapter 7 - Forest Products Laboratory

The boards may warp and cup, particularly in decking applications. These other weathering factors such as mildew growth, check­ ing, splitting, and warping, are often more important than the photo-oxidation, but these processes often act in concert to degrade the surface (see Figure 7.1).

WEATHERING PROPERTIES OF WOOD SPECIES ...

In the early stages of weathering, dark woods tend to become light and light woods, dark. Eventually, all woods become gray if fully exposed to UV light and water spray. As can be seen in Table 5, ∆L*values of some samples were negative after 336 h exposure, but values became positive after 672 h exposure.

Kataoka et al. (2007) have determined that UV light can penetrate the wood up to 66 μm (for radiation with wavelength of 246 nm) in the case of shorter wavelengths and up to 178 μm (for radiation with wavelength of 372 nm) in the case of longer wavelengths.

WEATHERING AND PROTECTION OF WOOD

Wood exposed to the weatherCan be protected by paints, stains, or varnishes. Paints provide the most protection to exposed wood surfaces, since they are generally opaque to the degradative effects of ultraviolet light and protect wood to some degree against wetting. Paint perfomance may vary greatly on different woods.

Water vapor fills the test chamber, which reaches 100% humidity at equilibrium. Vapor continually condenses on the test panels, which are kept at a lower temperature by room air on the back surface of the wood substrates. Condensation runs off the test panels and back into the water pan.
