Abstract
The paper evaluates the colour changes after weathering in the exterior of pinewood. It also monitors the influence of two examined factors on the colour change of surface; the two factors being: the length of exposure in the exterior and parts of wood – sapwood, heartwood. The submitted article deals with colour changes occurring on the sapwood and the heartwood. The changing colour of the surface was evaluated on samples exposed in the exterior for the period of 1 and 3 months. The colour was also evaluated on samples stored in dark places where there was no exposure to weathering. No significant colour changes were occurred on pine sapwood than heartwood. Significant colour changes were occurred on the exposure surface pine wood after weathering and cause different colour of surface. The higher colour change was found in pine wood (sapwood and heartwood) after first month weathering than between first and third month. The colour changes are easily seen with the naked eye.
