Sand the stairs: That's how it works!

The sanding of a staircase becomes necessary when a new coat of paint is planned or when the old paint is to be removed to show the raw material. Even traces of wear in wood can be compensated with the grinder. Depending on the desired result, the sanding process is rather superficial or very intense. Read our helpful tips!

Roughen surface before repainting

If you just want to roughen the surface, use 80's or 60's sandpaper and make sure you really reach all areas, even the hardest to reach.

For larger areas, such as the steps of the steps, you can use an orbital sander, narrow areas on the railing work best by hand. This work can also be carried out completely by hand, but then takes a little longer.

Make a rough surface anywhere by rubbing it over, dust the stairs thoroughly, and then start repainting.

Sand the stairs neatly

If you want to completely remove old layers of paint and other residues on your staircase, it is advisable to work with a hot air blower and spatula - or even with a suitable paint stripper. This allows you to effectively reduce the layers and then grind them.

Then you take the vibratory or eccentric grinder by hand and work first with coarse sandpaper over all surfaces. Narrow corners can be reached with the triangular delta sander, sometimes you might have to help by hand.

Plan several sanding cycles with increasingly fine abrasive paper. If you would like to leave the stairs wood-proof, you should at the end remove all scratches with the finest sandpaper. Do not forget the seal!

Practical tips for the grinding process

  • Remove any retaining strips from the steps before sanding.
  • Glue remnants of step mats should first be scraped off with the spatula.
  • Be careful when sanding protruding edges, as they can be sanded through quickly.
  • Any acrylic sprays in the joints should be removed with a joint scraper before sanding so that the acrylic does not get caught on the sanding unit.
  • Be prepared for patience and sensitivity when grinding. Above all, the final touch should be done skilfully.
  • If you want to level the surface of an old wooden staircase, you may need professional help so that everything looks good afterwards and the wood elements are not too thin.

Tips & Tricks

Take care of your health during this work and wear respiratory and eye protection. The fine sanding dust can otherwise deposit in the lungs, larger splinters may injure the eye.
