The respect of a few rules will allow you to avoid most disorders that may appear on a floor as a result of its installation.

Flooring blades

Let the blades acclimatize

48 hours.

This is the rest time you must leave to the blades (in their packaging) to acclimatize to the temperature and humidity of the room.

Room temperature

Between 15 and 20° C

This is the room temperature at which you can put your floor. If it is a low temperature floor heating, preheating is necessary.

Moisture content of the room for laying parquet

Between 40 and 65%

This is the relative humidity of the room air in which you can lay your floor. This means that any other work that generates moisture (tiling, plastering walls or ceilings...) must be carefully avoided.

Take into account losses when evaluating the quantity of floorboards

10%

It is the losses estimated because of the cuts for a poses of right parquet (in the French, cut of stone, etc.). Count 15% for diagonal laying and 20% for chevron laying. Remember to increase your orders accordingly.

Take into account the dilatation of the floor

5 to 8 mm

It is the width of the peripheral joint that you must keep between the floor and all obstacles such as walls, stairs, poles... It allows the floor to expand freely without the risk of deforming.

Lay on a flat surface

+/- 2 mm

It is the tolerance of flatness that you must observe by applying a rule of 2 m on your soil (in the contrary a patching may be necessary).

Lay the parquet on a dry support

3%

This is the maximum humidity level of the substrate. Otherwise, many disorders may appear. A new screed must be perfectly dry: count 15 days of drying per centimeter of thickness.
