Natural oils are the most natural and sustainable oils and provide reliable protection with just one application . They emphasize the wood’s inherent colour and provide superb accentuating properties. Optional hardening makes them even more resistant. They are partly even IMO-certified and suitable for sustainable construction projects under LEED, DGNB; BNB, etc. Solutions also exist for requirements in the coloured domain.
The second group – oils based on oil-modified alkyd resins – do not generally accentuate the colour of the wood quite as much. They also include the so-called hard wax oils . This term is associated with sustainability and is often used in the market. A glance at the contents reveals that nature is being "helped" a little here. These oils are equipped with special properties that a classic natural oil may not have at all, or not to the required intensity. This results in special oils with specific protective functions, or for special fields of application .
