Drawbacks of a Floating Cork Floor Drawbacks of a Floating Cork Floor

A floating cork floor is a beautiful and durable flooring option. Floating floors are not secured to the floor below. This feature enables a homeowner to install this flooring option over older flooring. However, there are some drawbacks to floating cork floors that should be considered before making your final flooring choice.

Exposure to Moisture

Cork is water resistant due to the suberin in it. It is not waterproof. When installing a floating cork floor, the cork is cracked between each of the planks. The cracks between the boards allow moisture to enter the cork through the board edges. This can cause the floating cork floor to become swollen, warped and discolored. This flooring option is particularly prone to moisture damage in a bathroom or kitchen, where there are higher levels of moisture.


In order to prevent moisture damage to a floating cork floor, it is necessary to re-seal the boards on a periodic basis. Boards that are pre-sealed will eventually lose their protective quality and will need a re-application of sealant.


Maintaining the seal on a floating cork floor will add an expense to your home budget. Leaving the floors without re-sealing them can lead to damage to the floors, which would also an expense, as the damaged boards would require replacement.
