Paint wood panels without sanding: Is this a good idea?


To really paint wood properly, it requires some important preparatory work, so that the paint really holds. Above all, the surface should be clean and stable, which in any case necessitates a previous clean-up. In any case, do wood panels still need to be sanded to be painted? Grinding causes a lot of dust, and it's also a rather laborious process - and then over your head!

Clean wooden panels before painting: That's how it works!

To get the wood surface clean properly, you can also use solvents such as turpentine or nitro thinner, so you wash off most of grease and furnace black. If the panels are slightly dirty, lukewarm soapy water may be enough.

Do not let the wood get too wet and dry it off quickly. When working with solvents it is recommended to wear appropriate protective clothing as well as extensive ventilation during and after the treatment.

Although the wood panels are clean, they have not yet been roughened for a coating. On too smooth surfaces, color does not last very well, not even on damaged old layers of paint.

Paint wood panels - only on well prepared ground!

If the surface does not flake off and it looks reasonably rough, you can try the painting without sanding. In this case, it is better to use an undercoat primer to give the paint good hold.

All in all, however, we recommend sanding wooden panels with rough sandpaper before painting and removing loose coatings, which provides more security for the durability of the paint. With these tips that works relatively easy:

  • Use 80's sandpaper.
  • Glide quickly over all surfaces.
  • Always sand in the direction of the grain.
  • Do not forget the wells.
  • Use a light handheld device with fine dust filter.
  • Wear a dust mask and goggles as a precaution.

If your wooden ceiling is only slightly soiled, sanding is also a better alternative to solvents in terms of cleaning. Work with hazardous chemicals should always be avoided wherever possible.

Tips & Tricks

Are your wood panels already painted? If you do not want to completely sand the coating, it is best to use a material that is as similar as possible to the old one. Water-soluble paint belongs to water-soluble paint, paint on wall paint, oil on oil.
