Step-by-step plan: removing graying from Douglas fir
Ready to remove the graying from your Douglas fir and protect it against the weather? Here is a handy step-by-step plan so you can get started right away.
Preparation
Start by cleaning the wood surface. Make sure loose dirt, such as leaves, is removed. A dry day without rain is ideal, so the wood can dry properly after the treatment.
Apply the product
Apply Osmo Power-Gel Houtontgrijzer generously to the grayed surfaces. Use a soft-bristled block brush for this. Let the product work for about 20 minutes for a deep clean. This effectively removes gray discoloration and any green growth.
Clean the surface
Once Osmo Power-Gel Houtontgrijzer has done its work, scrub the wood clean with a stiff brush while rinsing with water at the same time to remove the graying and dirt. This removes the gel together with the dissolved dirt. Do not use a pressure washer, to avoid damaging the wood.
Remove any white residue
If any white product residue remains, scrub it off with a stiff brush and rinse it away with the garden hose. The wood is now clean and free of gray discoloration. Repeat the process above if necessary.
Apply a protective coat
To protect your Douglas fir for the long term, apply an Osmo outdoor finish. This treatment delays graying and soiling of the wood. The oil also offers protection against moisture and dirt. You can choose to give the wood a new color or keep its natural look.
