Protection of wood with stain
To prevent the wood from graying, deteriorating and finally completely disintegrating, it must be intensively protected – through constructive measures, but also chemical and/or physical protection. The objective is to keep the wood dry as long as possible and to prevent the proliferation of fungus.
Structural measures such as sufficiently large roof overhangs, drainage of water through window sills, drips or the absence of contact with the ground, play an essential role here.
Chemical protection (eg Cetol Aktiva) against the proliferation of discolouring and wood-destroying fungi should only be applied if the type of wood used and the location of the building make it necessary. The impregnation must have good penetrating power and an excellent depth effect so that the chemical protection only acts where it is supposed to, ie deep into the wood.
Constructive measures and chemical protection are supplemented by physical protection (stain, glaze or saturator).
It consists of several layers to protect the wood against the weather and to prevent it from absorbing water. Its effectiveness is absolutely essential and can only be maintained by regular inspections, maintenance and repairs.
