When timber swells and shrinks repeatedly, resins in the wood are unable to preserve the fibres, in which case the wood begins to splinter. Well-oiled timber is water resistant, which helps to hold its moisture content better, with less fracturing as a result. The point of using wood oil is to introduce a rich oil into the timber and thus ensure water resistance. The wood oil should not be allowed to build a surface layer, so any surplus oil should always be removed in order to avoid staining. The greater the amount of dry material of the product, the greater the amount of oil needed and thus an increasing risk of a surface layer being formed. Make sure, therefore, to use a suitable dry material.
The surface should be clean, firm and dry. Porous wood should be removed. Wash with facade and mold remover, accompanied by a disinfecting product, rinse with water and allow to dry completely.
Either a brush or cloth can be used. Apply coats to whole planks and avoid double coating. Dry off any surplus oil and make sure to watch for grease and wood debris. Repeat the application until the surface is saturated and cannot absorb any more oil. This process should preferably be repeated several times a year with autumn being especially important. Take special care to do a proper job on end grains. Klassisk 30 Wood Oil, Gard Wood Oil and Orient Chinese Wood Oil are all suitable oils.
Maintenance is carried out in the same way as described above.
