High-gloss look: sand the clearcoat and paint over it

When repainting a car as well as when painting over wood, the right procedure for a perfect look is the be-all and end-all. You can find out what you need to consider when sanding and painting over clearcoat in our guide.

Overpainting wood: Sand clear varnish in between

With furniture, in particular, it happens time and again that a piece of furniture no longer looks appealing. To achieve a good, repellent effect on all types of stains, you need to apply several layers of varnish. First of all, you need to sand down the corresponding piece of furniture, such as a table or chair. Then you can start repainting. The so-called intermediate sanding of the clearcoat is extremely important here. In this way you avoid unsightly "noses" and prevent the paint from cracking while it is drying.

Proceed as follows to paint over a clear coat, such as a synthetic resin paint:

  • Wait until the paint layer is completely dry.
  • When painting, moisture penetrates the wood fibers. These rise up again - even with wood that has already been sanded down - due to the moisture.
  • When sanding with a sandpaper with a fine grain size (P240 - 400), the fibers are broken again, the surface becomes smoother and more pleasant.
  • With intermediate sanding of clear varnish you can also remove "noses " directly, these then do not pull through the different layers of varnish.
  • Thoroughly remove the sanding dust before painting over with another layer of clear varnish.

By sanding the clear lacquer, the individual layers can bond better, the result is consistently more durable and also visually more appealing.
After applying the last layer, you can sand or. Polish with very fine paper with a grain size of at least P800 for a high-gloss finish.
