Nailed installation:

Laying on joists:

parquet-3-150x150In the case where the flooring specialist has installed plaster-sealed joists, laying the flooring will not be possible before a further three weeks.
In the case of dismantling the previous wooden floor and keeping the joists, at least 20% of the latter are expected to be lost in the process. However, the installation of the new flooring can be done as soon as the previous one has been removed.

Glued installation:

Laying on concrete screed:

pro-design-parquet-3-150x150For new screeds, drying time is one week per cm.
Installation of the wood flooring may only be done with a hydrometric measure between 8 and 12%.
For an existing screed, the flatness tolerance is of one centimeter on a two meter ruler. If that is not the case, masonry work is to be expected.
There are however other leveling options such as installing a fiber resurfacing or a new screed.

Laying on particle boards:

Installation of the flooring will be done as soon as this step is completed.
This method is frequently used for leveling retrofits between 10 and 45mm.

WARNING:
ANY GLUED WOOD FLOORING INSTALLATION ON SCREED MUST BE PRECEDED BY A RESURFACING (TYPE P 3 min 3 mm)

Laying on dry screed:

parquet-2-150x150This method is frequently used for significant leveling retrofits (between 45 and 100 mm).
This screed consists of a granular Vermaspha support and clay pebbles or leveled sand which is then covered by fiber and particle boards .
This technique has several advantages: an excellent acoustic insulation (between 20 and 30 dB), a glued or nailed wood flooring as well as a minimal drying time.
