Cork floors are natural soils and are therefore subject to special treatment. The first laying of a cork floor should always be carried out by qualified personnel. Cork floors, like any other floor, are mechanically and thermally stressed. Thus, over time, it may be necessary to ground this floor because it has become soiled and worn out, perhaps even stained. This is possible with a little manual skill. You should take care that the cork has a thickness of at least 4mm and is not laid as a veneer.
What you need to sand the material
- A CC single-disc machine with Velcro and Superbad
- Grinding grids in the grain size 60, 120, 150
- possibly a triangular sander with identical grain size
- Linseed oil or hard oil
Now it can start
- Clean out the room thoroughly and remove all skirting boards, profiles, and rails.Gently tap the protruding nails again.Then clean the floor thoroughly with a broom or vacuum cleaner.
- The connection and sealing joints should be carefully covered so that no silicone residues form during grinding.Check whether the lining has loosened somewhere, and if necessary, glue it again.
- Now mount the Klettgitter and the Superpad, including the grille.They begin with new floors, with 120 grains, then use the 150s in the next sanding cycle.For older soils, start with 60 grains, then 120, and the third with the 150s.
- The ground is then ground in the direction of the grain.Before working in the opposite direction, lift the grinder briefly and then reattach it.The floor must then be thoroughly cleaned again.Be sure to remove all old varnish and oil layers.Then start the second grinding cycle with increased grain size and proceed as in the first time.Older soils then need a fine grinding with the 150-grain size.The surface performance of the grain size is adapted to each grinding path.Finally, thoroughly clean the floor and remove the adhesive strips.
- For impregnation, thoroughly brush the floor with oil.You should soak the soil properly.Superfluous oil can then be wiped off.Then let the ground dry for one or two days.Then the cork floor gets a second thin coat, which has to dry again.Finally, seal the floor with wax and polish it with a brush.
Here are some tips
- For radiators, use a triangular sander. Use pads with pads as they are more elastic than sandpaper. Be careful not to use a fast-running grinding machine.
- Grinding machines are available for rental in good specialist shops for floor coverings, but also in some hardware stores. Just ask, before you decide to buy.
- When sanding, we recommend wearing a dust mask and eye protection. And work, if possible, with open windows.
- After sanding, you should empty the dust bag of your vacuum cleaner and store the dust bag in a fireproof place overnight. The dust can ignite with time-delayed metal particles.
- It is sufficient for you to sweep your cork floor to clean it and wipe it with a damp cloth. A seal with super wax and oil balm guarantees a long shelf life.
