What you need for this tutorial;
Want to paint impregnated wood and looking for a durable, opaque finish? Good news: with the right preparation and supplies, you can give your wooden fence, garden shed or other outdoor wood long-lasting protection against moisture, UV radiation and dirt. In this tutorial, we explain how to treat impregnated wood, whether it is new, grayed or previously painted.
Preparation: how to get the wood ready for treatment
Before you start applying Osmo Landhuisverf, it is important to know what condition the wood is in. The right preparation ensures good adhesion and a long lifespan for your paint layer.
Untreated wood: New, impregnated wood does not need to be sanded. However, you must first let it weather for 4 to 6 weeks, so that the impregnating agent can be properly absorbed and the maintenance interval is extended. After that, you can treat the wood directly with Osmo Landhuisverf.
Previously treated wood: Has the wood been painted or stained before? Then you must first remove the old layers by sanding. We recommend sanding with the following grit sequence: 40-80-120. This creates an even and smooth surface.
Maintenance or applying a new coat: Want to refresh an existing layer? Then clean the wood thoroughly with Osmo Terrasreiniger to remove any stains. Has the wood turned gray? Then first use Osmo Power-Gel Houtontgrijzer. After drying (24 hours), you can apply a new coat of Landhuisverf right away.

Step-by-step plan: painting impregnated wood
With this step-by-step plan, you treat your outdoor woodwork in a durable way. Osmo Landhuisverf offers good protection and is suitable for almost any type of wood used outdoors, such as pine, spruce or Douglas fir.
Stir the product thoroughly
After opening the can, the oil and wax must be mixed well. Stir the Landhuisverf for at least 2 minutes for an even result.
Apply the first coat
Apply the first coat with a brush or block brush to dry and, if necessary, sanded wood. Work with the wood grain for a natural-looking finish.
Note: do not apply the product in rain or high humidity.
Correct if necessary
Within 15 minutes of application, you can still correct small mistakes such as brush hairs or start marks while the paint is wet.
Let it dry
Let the first coat dry for about 10 to 12 hours at 23 °C. Drying times may differ in colder or more humid weather.
Apply the second coat
Apply the second coat in the same way as the first. This coat also dries within about 12 hours. After that, your wood is fully protected against weather, wind and dirt.
