Abstract
The heat treatment of wood is used in order to improve durability and to reduce hygroscopicity and dimensional changes. Pine and spruce were heat-treated at 225 degrees C for 6 hours. The panels were coated with the different types of surface finishes that are commonly used on exterior cladding, joinery and fences in Finland. Performance of the heat-treated and untreated specimens was monitored during three years outdoor exposure. The moisture content in the heat-treatment boards was not observed during the exposure. The original dark colour of the heat-treated wood is not stable to UV-light. The weather resistance of the heat-treated wood was improved by the coatings. Penetration of the coatings into the heat-treated wood and adhesion were good. The commercial paints tested can be recommended for heat-treated wood.
