1. Brush and scratch

When sanding the wooden facade, timing is important. The most important tip is therefore the weather forecast, because you need good weather for several days. You should only start scraping off the old layers of paint after it has been absolutely dry for a few days. Scrape off loose paint and moss first with a spatula and then with a wire brush.

2. Coarse cut

A wooden facade is prepared for the new impregnation or wood oil in several sanding steps. With a 60 grit you get down the coarse paint residues, which are already easily removed. Take the sandpaper out of the machine in between and knock it out. This way your sandpaper will last a little longer and will not become so full of sanding dust. In the second gear you sand the facade with an 80 grit if possible. But only sand on dry days. The sun may fall on the wooden facade while sanding, but not later when painting or varnishing.

3. Fine tuning

If the facade is not to be treated because a silvery patina on larch wood, for example, is desired, a fine sanding with a 100 grit may be sufficient. For a fine lacquered surface, however, the wood is sanded with at least 120 grit sandpaper. However, you usually do not need the 150 grit, which is common for furniture, for the facade.

Tips & Tricks If you have a facade made of a particularly resinous type of wood, your sandpaper will quickly clump and stick. Many professionals therefore now use an organic granulate that is blasted onto the facade with plasma pressure. This method is particularly recommended for sanding the facades of log or log houses.
