You should know that before you sandblast the stairs!


At first, it sounds like a good idea to just ignore the chemical-heavy paint strippers to remove old layers of paint. Instead, you reach for the sandblasting unit, which promises less manual effort in addition to solvent-free air. However, we recommend weighing this decision well, because it has its catch.

Sandblasting wants to be learned

In a sandblaster, the mostly quartz-containing cleaning agent is sprayed onto the surface with vigorous air pressure. In this way, paint and varnish can be easily broken off, without the craftsman having to spend much energy.

However, sandblasting is not the same as sandblasting: there are many different processes that are suitable for different purposes and surfaces. Which of these is suitable for you, knows the expert. Here is a selection:

  • vacuum rays
  • Glass bead blasting
  • wet blasting
  • wet abrasive blasting
  • dry Ice blasting
  • blasting

Also the handling of the sandblaster is not that easy. We recommend a trial blast on old wooden boards to get into practice.

Sandblast stairs: You should pay attention!

Keep in mind that among the types of wood only hardwood is suitable for sandblasting. Relatively many stairs are made of pine, some of spruce. Softwoods are usually not hard enough and are damaged by mechanical stress.

However, hardwood also has weak points: the softer light-colored annual rings wear off faster than the dark ones, so your staircase will probably look rather rustic after blasting. Maybe you like it - or you simply sand the surfaces smooth again.

Intact stone, concrete and metal surfaces tend to resist sandblasting, but they do get a rather rough surface. Do you want shiny surfaces, so a post-treatment is in demand.

Protect your health!

If you sandblast your own stairs, do not forget the corresponding protective equipment. Mouth and eye protection are absolutely essential in this work, otherwise threatened damage to health.

Tips & Tricks

Anyone who has a high-quality sandblasting machine and masters the fine adjustment can not only sand blast stairs, but also "engrave" surfaces. Try painting a pattern on a softwood board.
