Solid wood flooring - Requirements on the subfloor
Requirements on the subfloor
Basic requirements for installing solid wood flooring are that the substrate is stable, clean, dry and even. Irregularities exceeding 2mm per 1m have to be evened out with a suitable filler/ spackle. When installing on an old hardwood floor or on particleboard flooring any loose planks need to be screwed with the sub-structure to help silencing potential squeaks in the old floor. The new floorboards should be installed in transverse direction to the old boards. For both stability and health reasons, textile floors are not suitable as a substrate and have got to be removed. Installation on PVC-, CV- and linoleum-flooring is possible only if the floor coverings are glued-down over their entire surface and no loose areas are present.
Screed floors must not exceed the following residual moisture levels:
Generally, moisture level measurements of screed floors should always be conducted with a suitable measuring device. For reasons of precaution a 0.2 mm thick PE-foil should always be used as a moisture barrier on top of the screed floor (the individual foil strips need to overlap at least 30cm, overlaps are fixed with adhesive tape, all around the room the foil needs to run up the walls for several centimeters and can be trimmed down with a cutting knife after the skirtings have been installed). Alternatively, you could use Duo-Protect, a product that combines both transmission noise insulation and moisture barrier in one.
Parador Solid Wood Flooring with tongue-and-groove profile
Parador’s solid wood planks are suitable for installation with screws on sleepers, old hardwood floors, particleboard flooring or OSB (min. 22 mm thick) and also for all-over adhesion on screed floors. Parador Solid Wood Flooring in the 128 mm and 137 mm wide versions can also be installed as a floating floor for example on Parador Duo-Protect using the special installation clamps. When solid wood planks are being installed with screws, we recommend using OSB or particleboard flooring as a sub-structure. Putting up your OSB or particleboard flooring, please make sure that these boards run across the direction that your solid wood planks are going to run.
Parador Solid Wood Flooring with Click-profile
Parador’s solid wood planks with Click-profile are suitable for floating floor installations on screed or old hardwood flooring, particleboard flooring, OSB and for all-over adhesion on screed floors. We recommend installing the planks with Parador Duo- Protect or an alternative system with at least 0.2 mm PE-foil and for example Parador Uno-Protect, Akustik-Protect or Plan-Protect plus 0.2 mm PE-foil as underlays.

Screed floors must not exceed the following residual moisture levels:
| Anhydrite flow screed | Cement screed | |||
| without subfloor heating | max. 0.5 CM % | max. 2.0 CM % | ||
