 Abstract

Wood exposed to conditions such as sunlight and rain undergoes a phenomenon known as weathering. Colour change and cracks formation in the wood can be evaluated in order to determine the effect of environmental conditions. This study determined the natural weathering of the important trade timber species in Mexico Cordia elaeagnoides, Dalbergia granadillo, Enterolobium cyclocarpum, Hura polyandra, Swietenia humillis, Tabebuia donell-smithii, Tabebuia rosea and Fagus sylvatica as control. The procedure was performed according to EN 927-3. The action of environmental factors was monitored during five months with changes in appearance and colour and cracking formation also determined. The results indicated that Cordia elaeagnoides (ΔE19.7) and Dalbergia granadillo (ΔE 15.9) showed the lowest values in colour change.
