Do you need to treat Douglas Fir?

Douglas Fir can be left untreated outdoors, but it then turns grey and can crack due to changing moisture levels. To retain the warm colour and protect the wood better, treat it with UV-Beschermingsolie, Natuurlijke Olie-Beits or Landhuisverf on vertical wood, and with Terras-Olie on a terrace.

What is the best stain for Douglas Fir?

For Douglas Fir, use Osmo Natuurlijke Olie-Beits. It is a primer and top coat in one and suitable for all outdoor wood. Apply two coats. Pigmented colours protect against UV, the clear 701 does not. For an opaque colour, choose Landhuisverf.

Which oil should you use for Douglas Fir?

For vertical Douglas Fir, use UV-Beschermingsolie: first one coat of 427 Douglas, which keeps Douglas Fir light, followed by 420 clear. Treat a Douglas Fir terrace with Terras-Olie 004 Douglas, optionally with Antislip Terras-Olie 430 as a third coat for grip.

Can you paint Douglas Fir?

Yes, you can paint Douglas Fir with Osmo Landhuisverf. It covers well, but the wood structure stays visible, and the paint does not peel. Touching up is possible without sanding. Let new Douglas Fir weather for six weeks first and sand it lightly, so the paint adheres evenly.

How do you restore Douglas Fir?

First treat greyed Douglas Fir with Osmo Power-Gel Houtontgrijzer. It removes the grey layer and brings back the orange-brown colour. Let the wood dry properly and then apply a new coat of oil or stain. Never use a pressure washer.

How often do you need to stain Douglas Fir?

Check Douglas Fir every year, especially the side exposed to sun and rain. If the colour or water repellency has decreased, clean the wood and apply one thin coat. How often this is needed depends on the location and the product chosen.
