Pine costs less and looks gorgeous with stain, paint or left unfinished. Film-forming (lasure, paint, varnish) is also compatible with autoclaved pine, as long as the wood has been thoroughly dried. Find a spot with plenty of air circulation, preferably outside or by an open door, to apply the finish. Communities tend to put their faith in autoclave treated pine for all outdoor structures because it is a competitive material with a vast range of applications that has proven its worth. Over time, the colour from the treatment begins to fade and the autoclaved pine gradually turns grey; just like non-treated wood but perhaps a bit slower. Cedar wood is porous and contains little air pockets in the The temperature is never raised, which is by definition the most energy-consuming process of all industrial operations.

This is because the youngest areas of the wood, known as the sapwood (a pale yellow wood), are susceptible to mould fungi and even rot, depending on their exposure to extreme weather conditions. NOTE: the risk of the wood being affected by fungi depends on the weather conditions and the conditions of use (temperature, relative humidity, driving rain, structural conditions, design details and maintenance provisions).
