How long should I wait before I can lay laminate flooring on a fresh concrete floor or screed?

Allow your fresh concrete floor enough time to dry before installing your laminate flooring.

you should wait one week per cm of screed (thickness) up to 4 cm before you start to lay your laminate flooring. Wait twice as long for every additional cm (thickness) up to 6 cm and wait 4 weeks for every additional cm beyond 6 cm.

  • Wait one week per cm of screed up to 4 cm
  • Wait two weeks for every additional cm up to 6 cm
  • Wait four weeks for every additional cm beyond 6 cm
  • Use an underlay with build-in moisture barrier
  • Make sure the room is well ventilated

Why wait?

It takes time for moisture to move from the bottom of the concrete layer to the surface. If you don't wait long enough and you don't have a damp screen in place, moisture that reaches the surface can cause your laminate to swell and come up. Make sure you use a plastic foil or an underlay with a moisture barrier. Several of our Pergo underlays have a built-in moisture barrier.

Screed thickness Advised drying time
<4 cm 1 week per cm
5 cm 6 weeks
6 cm 8 weeks
> 6 cm + 4 weeks per additional cm

Moisture Meters

If you have a moisture meter at your disposal you can measure the moisture content of the concrete subfloor. Follow the instructions in the manual. In most cases this comes with a handy table that contains the maximum values in different conditions.
