What care does Douglas fir wood need?


Douglas Fir wood is still one of the most popular and commonly used woods outdoors and for the patio. Like any other wood, Douglas fir needs a bit of care and protection from time to time. What you can do and what you should not do is explained in this article.

Regular cleaning

One can not stress it often enough: Regular cleaning is the backbone of every care. Dirt should always be removed as early and thoroughly as possible. For this you should use only suitable means. Wood which has been freed of dirt and possible pollutants also remains resistant for much longer.

Protection by wood oils

This keeps the wood well protected from harmful influences far below the surface. Whether protection is necessary at all, read here.

Universal oils

You can - as for any other wood - use linseed oil or linseed oil varnish. These two oils (boiled linseed oil is boiled linseed oil) are absolutely natural preservatives that have been proven for centuries. They are even food. Linseed oil varnish dries significantly faster than pure linseed oil (which can take up to 10 days to complete drying). For linseed oil varnish, this only takes around 24 hours at 20° C.

Douglas fir oil

In the trade, there are also specifically on Douglas fir matched protective oils, which often still color pigments and a highly effective UV protection. Thus, the graying and the formation of a patina is prevented, in addition, the color pigments the colors of individual wood parts (such as decking) match each other. The best care measure is the regular oiling - often on heavily used areas (roads) and regularly once or twice a year for the entire wood.
