To properly seal a cork floor


A seal is the easiest way to protect a cork floor. You can easily apply it yourself - but what you have to look out for is explained here.

Sealed instead of waxed

Sealers are a very effective way to permanently protect a cork floor - oil and wax are another option, however, so that the pores of the cork floor remain closed and so damage is avoided, the procedure must be repeated regularly. On the other hand, sealants remain perfectly intact for a whole decade, provided that the floor is kept in the proper manner and under normal, normal conditions. Only then must be then sanded and resealed.

Step by step explained: sealing cork floor

  • Sealing varnish for cork, ev. Also as nano-varnishing varnish
  • duct tape
  • Sandpaper or sanding machine
  • Vacuum cleaner with high performance
  • sealing rolls
  • ev. also lint-free cotton cloth

1. Grind the floor finely

After laying, you should first sand the floor finely. The removal does not have to be very large - it is more important that the surface is ground evenly fine. This keeps the sealant even in all places.

After sanding, you should thoroughly vacuum the floor several times to remove all sanding dust. Then carefully tap the skirting boards with tape or painter's tape.

2. The first coat

The first job has to be very thin and very even. This will prevent too much paint from swelling the cork floor in some places.

3. The further paintings

When the first coat of paint has dried - usually after 12 hours on most topcoats - you can apply the second and third coats with at least a day's spacing. Here you can apply a bit fuller, but it should be very even here. After sealing your cork floor is usually accessible again after 48 hours, but that depends on the properties of the sealing varnish.

Tips & Tricks

Work here slowly and always away from the existing light source to better see if your order is really evenly even.
