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.
Why does parquet swell?
Wood is very sensitive to moisture. Particularly sensitive is parquet, which is only oiled or waxed. With painted parquet, the risk is lower. When does parquet expand? Basically, whenever too much water hits the wood. The “hidden moisture absorption” can be regulated by paying attention to the correct humidity in the room (approx. 60% relative humidity). When wiping the floor, only a fog-moist cloth should be used – no steam cleaners or drip-wet wipes! If water has been accidentally spilled, the mishap must be rectified as soon as possible. The situation can become particularly critical if hardwood flooring is lying in a kitchen. If you have the possibility, the pure cooking and rinsing area should be better tiled, then “accidents” with water are no problem. If parquet is laid in the bathroom, special rules apply.
Why is parquet squeaking?
Parquet can squeak if the wood “works“, i.e. either dries out or swells. In the joints, it can lead to displacements. Sometimes there are also laying errors: The substrate is not completely flat, with floating laid parquet the necessary stretching fins are not available. When tensions occur in the wood, squeaking occurs. This is remedied by measures similar to those of a creaking floor. Humidity and temperature must fit. You can carefully determine which ground elements cause a lot of noise. It often helps to tighten the planks. This is done, for example, when old floorboards squeak in places. The expert screws directly from above into the planks – exactly where the wooden beams run. This way, the boards are additionally fixed and no longer squeak. The resulting holes can remain open (rustic look) or be closed with a wooden putty. The latter only makes sense if the floor is renovated anyway.
Why is parquet creaking?
A creaking parquet floor can have several causes. Often the unpleasant noise occurs in places that are very often committed and stressed. Cracks in the wood are also possible, caused by the change between heating air in winter and heat-free periods. Infiltclassifyable moisture can also cause the parquet to crack. Often, however, the substrate is also to blame – when moisture forms here and dries again, the parquet creaks. In case of doubt, you should commission a specialist who will take a close look at the floor.
