Oiling pinewood - what's in it?

Wood surfaces can be treated in a variety of ways. One option that works well with pine wood is oiling. What advantages the oiling of wood brings, what properties the surface has after oiling, and what should be considered when using wood oil, can be found here.

Difference between oils and other surface protection types

All common types of surface protection - such as varnishing (most commonly used in the factory ex factory) but also sealing - form a protective layer on the surface of the wood. This protective layer prevents the penetration of dirt and moisture into the wood. When oiling, however, no such protective layer is formed. The liquid oil penetrates to a certain depth (usually 1 - 2 mm) in the wood and a and cures there as a tough layer. This protective layer then lies around all wood fibers.

advantages

Compared to other processes, pinewood oil has some advantages:

  • Wood oils are tailored to the ingredients of the pine wood
  • There are no problems with resin as in painting and glazing
  • Oiled wood is very durable
  • Oiling is easy and inexpensive to apply and can be done by anyone
  • The feel of the wood is much more natural and pleasant than with painted wood
  • Oiling is much more ecological than painting, and it is much less harmful to the environment

Suitable oils

linseed oil

A very good all-purpose oil, which can be used on other types of wood in addition to pine wood, is linseed oil. Linseed oil is a food that hardens on contact with light and air to a viscous mass. 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 woods. Drying can be accelerated by cooking the linseed oil - it then becomes the well-known linseed oil varnish.

Tung oil

The so-called Tungölbaum (also Holzölbaum) grows in China. The tung oil has been used for a long time to conserve and protect wood. It also forms the basis of many special oils.

Special oils in the wood trade

The wood and wood supply trade also offers special oils tailored to the respective wood species. The respective base oil are often added more natural ingredients (so-called stand oils, but also dammar or castor oil). Occasionally, waxes are added. To accelerate drying, so-called siccatives are added.

Renew oil application

After the fresh (or sanded) wood has been soaked with oil two to three times, the protection forms within a short time. Especially in stressed areas you should repeat the oil frequently (several times a year), otherwise a re-oiling is sufficient about once a year.

Tips & Tricks

Important: never leave oil-soaked rags crumpled up - there is a danger of self-ignition in all oils! You should never underestimate this risk. Rags always spread outdoors to dry completely.
