Parquet darkens for several reasons. Some types of wood change colour with age and become darker. In addition, the influence of light and sunlight plays a major role in light wood floors. If the room is exposed to permanent sunlight in summer, the parquet can darken relatively quickly. You can prevent the effect of UV rays with closed blinds or shutters. Window films that keep out too much sun are also practical. On the other hand, the darkening shows that wood is a natural material. The parquet floor often looks nicer when it is no longer “brand new”. Be careful when carpets are lying on the floor – over time it can become very clear what the floor originally looked like when the carpet is removed again one day. Even transparent floor protection mats allow light to pass through, but filter it strongly. Therefore, colour differences can be expected even when removing them.
When parquet becomes cracked in winter, the humidity in the room is not right. It is usually not the quality of the parquet! The natural product wood can bind and release water (hygroscopicity). The wood moisture content with which parquet is delivered and laid is approximately nine percent with a deviation of 2 percent each way up and down (different limits apply depending on the type of parquet). In order for this condition to remain unchanged, a humidity of 55 to 60 percent is required. These factors change due to the weather and heating behaviour. This causes small cracks to appear, but these recede again when the room climate is correct. One should avoid strong temperature fluctuations when heating. A good preventive measure is a humidifier, preferably a so-called evaporator, which keeps the air humidity constant at a level of 55 to 60 percent.
Parquet is a natural material, wood can react sensitively to strong temperature fluctuations. You can prevent this by not processing parquet immediately after purchase and transport. The material must be acclimatised to room temperature before laying. Store the planks (in their packaging) in the room where they will later be laid. The storage period is at least 48 hours. The surface should be even.
Important so that the properties of the parquet are not affected: The room temperature should be between 17 and 25 degrees Celsius at most. If the room has floor heating, the temperature of the floor heating must be at least 15 degrees and at most 20 degrees. Ideal is an air humidity in the range of 50 to 65 percent. After installation, the parquet is much less sensitive. Correct storage prevents the elements from warping or swelling before installation. If the parquet is stored for a longer period of time, room temperature and humidity must be checked regularly.
