Fungus & insect attack

High moisture content is a prerequisite for the timber to be attacked by various types of fungi. It is therefore important to wooden structures designed so they are kept as dry as possible.

Impregnation

Impregnation with wood preservatives is an effective protection against rot and provides some protection against blue stain and mold.

Wood and wood products may be protected against blue stain and mildew by treatment with various fungicides. It prevents the formation and the further development of aggression. Treatment is usually carried out by dipping, spraying or brushing. Several fungicides appearing on the market are not resistant. Treatment must therefore generally be repeated at intervals if you do not take steps to keep the wood dry, for example, annually.

Impregnated wood, for example patio deck and patio furniture, should be coated at least once a year with a fungicide containing heavy oil, partly as protection against mold and blue stain, partly to counteract cracking.

Construction timber can be attacked by various insects, for example old house borer. The risk of attack is locally very variable.

Most drugs currently used for impregnation in class NTR / M, NTR / A and NTR / AB offers protection against insects.
