This is how cork is sealed


Similar to parquet, a sealant is a comprehensive protection for your cork floor, which permanently closes the pores and thus avoids damage and dirt entering the cork. How to easily seal cork, read here.

Sealers as permanent protection

Unlike the oiling and waxing of a cork floor, the seal provides lasting protection. As a rule, the seal only has to be renewed every ten years - while oil and wax often require reworking several times a year.

Of course, the degree of protection also depends on the particular sealing varnish - there are also products with particularly interesting properties, such as sealing varnishes, which form a nano-surface. But always make sure that the selected product is actually specifically suitable for cork - otherwise you can seriously damage your floor.

Step by step instructions: Cork seal

  • sealing lacquer
  • Tape or painter's crepe
  • Grinding machine (or hand grinder)
  • vacuum cleaner
  • Sealing rollers (you need several of them)
  • cloth

1. Grinding and cleaning

Before applying sealer, the floor must be thoroughly sanded. This requires a great deal of care - the floor must be ground evenly so that the sealing varnish can adhere well afterwards. For larger surfaces, a grinder is an advantage - but it takes a bit of practice to use it properly. They may also lend you in a hardware store.

2. Prepare base coat

Suck off the sanding dust very thoroughly and glue all skirting boards very precisely with the paint crepe.

3. Apply sealing varnish

Apply the sealing varnish evenly with a roller. The first coat must be very thin so that the floor does not swell at any point. But it also has to be done very evenly - always working away from an existing light source - so you can see better if you apply it evenly. At intervals of one day (for most products) followed by a second and third order, which can be a bit fuller, since there is already a base layer. But always follow the instructions of the product manufacturer regarding the times.
