Parquet is a robust and durable flooring. However, it may happen that a new floor is desired in the course of renovations or redesigns and the choice falls on laminate. This raises the question of the correct procedure to lay laminate on parquet.
Which parquet is suitable as a substrate for laminate?
In general, it should be noted that laminate cannot be laid on every parquet.
Only fully glued parquet is suitable as a substrate for the new floor – in this case, nothing stands in the way of direct installation.
Laying laminate on floating parquet, however, is not recommended. In this case, the parquet should first be completely removed before the new floor can be laid.
What should be considered when laying laminate on parquet?
Apart from the fact that the parquet must be fully glued, there are a number of other factors involved in the laying of laminate must be taken into account on parquet:
Just like the screed during the new installation, the parquet must also be clean, dry and flat before the laminate can be laid on it. Larger unevennesses should be adjusted in advance by grinding or spading with compensating mass. Lower unevennesses of approx. 1 to 2 mm, on the other hand, can usually be compensated with a footfall sound insulation for parquet.
The impact sound insulation is highly recommended for laminate on parquet because the combination of the two floor coverings would otherwise be very noisy.
Moisture-permeable insulation materials, such as cork or cardboard, are suitable. It is even easier if a laminate with integrated impact sound insulation is used at the same time.
A vapour barrier, on the other hand, should rather be dispensed withwith laminate on parquet. Parquet is a wooden floor that absorbs or releases moisture. This could easily create waterlogging under the PVC film, which in turn would cause permanent damage to the ground.
In order to achieve more stability of the floor, the laminate should be laid transversely to the existing parquet. It should be noted, however, that a change in the presence of light can result in a different joint pattern.
The use of click laminate is recommended, as it can not only be laid relatively easily without expert help, but can also be removed without leaving any residue, as it does not need to be glued.
Since laminate expands or retracts in the event of temperature fluctuations, expansion jointsshould be taken into account when laying laminate on parquet. This gives the floor the necessary leeway without undesirable jointing or dents.
If laminate is laid on parquet, the height of the floor changes. Therefore, it may be necessary to shorten door frames or sheets accordingly. Elevation differences in transitions can be covered with profiles.
