Wood surfaces can be treated in a variety of ways. A possibility that is also excellent in pine wood is the oil. What advantages the oils of wood brings which properties has the surface after oil, and what to consider when using wood oil.
Difference between oils and other surface protection types
All common types of surface protection - as painting (most commonly used in the industry ex works) but also seal a protective layer on the surface of the wood. This protective layer prevents the ingress of dirt and moisture in the wood. In contrast, no such protective layer is formed when oiling. The liquid oil penetrates the wood to a certain depth (usually 1 - 2 mm) and hardens there as a tough layer. This protective layer then lies around all wood fibers.

Oiling pine wood has a number of advantages over other methods:
- Wood oils are precisely matched to the ingredients of the pine wood
- there are no problems with resin like with painting and glazing
- oiled wood is very durable
- Oiling is easy and inexpensive to use and can be done by anyone
- the feel of the wood is much more natural and pleasant than that of lacquered wood
- Oiling is much more ecological than painting and is far less damaging to the environment
A very good universal oil that can be used on other types of wood in addition to pine is linseed oil. Linseed oil is a food that hardens to a tough elastic mass when it comes into contact with light and air. This usually takes between 2 and a maximum of 10 weeks. Linseed oil is particularly inexpensive. It is also often the basis of specialized oils for individual types of wood. Drying can be accelerated by boiling the linseed oil - it then becomes the familiar linseed oil varnish.
The so-called tung oil tree (also wood oil tree) grows in China. Tung oil has been used to preserve and protect wood for a long time. It also forms the basis of many special oils.
Special oils in the timber trade
The wood and wood supply trade also offers special oils tailored to the respective type of wood. Often other natural ingredients are added to the respective base oil (so-called stand oils, but also dammar or castor oil). Waxes are also occasionally added. So-called siccatives are added to accelerate the drying process.
Renew oil application
After the fresh (or sanded) wood has been soaked two or three times with oil, the protection develops within a short time. Oiling should be repeated frequently (several times a year), especially in stressed areas, otherwise re-oiling is sufficient about once a year.Tips & Tricks Important: Never leave oil-soaked rags rolled up - with all oils there is a risk of spontaneous combustion! One should never underestimate this risk. Always spread the cloth out and let it dry completely outdoors.
