SCREEDS AND CONCRETE FLOORS MUST BE DRY BEFORE THE FLOOR COVERING IS INSTALLED
Regular checking of moisture content during the drying out period of a new concrete floor or floor screed is important to ensure it has reached sufficient dryness to accept the floor covering.
Excessive moisture in concrete floor slabs and screeds can lead to a host of problems in all types of floor coverings such as: adhesive degradation, delamination of the floor covering from the slab and within itself, condensation, blistering, movement and deterioration of the covering.
In the case of wood flooring, excess moisture can lead to swelling, cupping and movement of the wood which can lead to floor failure and even structural damage. Excess moisture can also lead to mold growth. Most of these problems can be related to the floor covering being installed on a sub floor that is not sufficiently dry. It is therefore important to ensure that the floor slab or screed is sufficiently dry enough to accept a covering or coating.
