Preparation before painting with linseed oil paint

To achieve the best possible results when painting with linseed oil paint, it is important to prepare the surface correctly. In this article, we go through the most important steps to prepare the surface before painting with linseed oil paint.

Sand or scrape the surface

Scrape and sand the surface to remove old loose paint. The linseed oil paint follows the substrate, so the better the preparatory work is done, the better the end result will be.

Clean the surface

Make sure the surface is clean, dry and free of dust, dirt and loose paint. Use a brush or a damp cloth to remove dust and dirt. If there is mold or algae on the surface, use a mold and algae remover to clean the surface before painting.


There are several schools here.

  • Inside, we recommend diluting the paint with linseed oil the first time you iron it, so that the paint is thin and easy to iron out. It is also possible to paint with an interior linseed oil primer .
  • On the outside, you can either apply alinseed oil paint base first or dilute the paint with solvent as a base. Some manufacturers recommend that you also dilute the paint externally with linseed oil.

Regardless of which method is chosen, the base color must be painted thinly.

Check compatibility

If you are painting over an existing color, check that the linseed oil color is compatible with the existing color.

In summary

By carefully preparing the surface before painting with linseed oil paint, you can achieve a durable and beautiful result. Clean, sand, prime and check compatibility to give the paint the best possible conditions to adhere and last over time.
