In the interior in particular, the question arises as to how wooden beams can be treated without using paints and varnishes that contain solvents. Oiling the wooden beams is the most beneficial solution in terms of health if purely vegetable oils are used. Linseed oil has proven to be the most ideal oil for both priming and finishing.
Support the oiling result
In most cases, interior wooden beams should retain their natural grain and structure. The usually dry environment means that there is no need to impregnate the wooden beams. To give the wooden surfaces a protection that helps against house dust and normal household contact by touching, leaning against or propping up, linseed oil is well suited.

If the wooden beam is to be painted in color, wood oils can be mixed with color pigments. With these products, however, you should always ensure that they are solvent-free. Anyone who paints and treats bars can support the lasting effect of the purely natural oiling with foresighted measures and behaviors. Suitable measures to extend the oiling interval to several years are:
- Permanently good room ventilation in the sense of boost ventilation
- Free "air-bathed " position of all exposed bar surfaces
- Immediately remove high and standing humidity in the bathroom or kitchen by ventilating
- Follow the processing instructions regarding room temperature and wood preparation
Border and outside areas
If the oiling is to be carried out on wooden beams that are partially in the open, such as roof truss beams under roof overhangs, special pre-treatments or developmental conditions must be observed depending on the type of wood. Deciduous trees should only be oiled after they have been exposed to weathering for at least one year so that most of the wood tanning agents are already washed out.
Conifers are often very resinous or have concentrated "resin nests ". These must be washed out with turpentine before oiling. Some trees have a high density with low porosity. Larch or oak wood can be sealed directly with the finalizing oil without a primer due to its low absorbency.Tips & Tricks If you cannot find a special beam oil in hardware stores or specialist shops, or if the selection is not enough, you can include all natural furniture oils in your search. Note that waxes, like for parquet and wooden floorboards, are only suitable for a few types of beam.
