Walnut
Walnut wood is a natural product and reacts to environmental influences. Cracks, fissures, and warping of the wood occur due to the environment in which the product is placed. By following the advice below, damage from environmental influences can be limited.
General Advice
Humidity and temperature
Fluctuations in humidity and cold/heat will often lead to shrinking, expanding, warping, cracking or breaking; such fluctuations should be prevented. The relative humidity varies daily and depends on weather conditions. However, it is essential to maintain a constant level of relative humidity in the room where the furniture is located.
Advice:
- Maintain constant indoor humidity, preferably around 55%.
- Regularly check the humidity with a hygrometer; these are often built into modern thermometers and heating devices.
- If necessary, use humidifiers or dehumidifiers.
- Keep the room temperature constant.
Sensitivity to moisture and light
Exposure to moisture or heat can cause moisture to get under the finish, or the existing moisture in the wood can accumulate under the finish, leading to stains. Stains or rings can be the result of improper use.
Advice: Use coasters and placemats to prevent contact with moisture and heat, and immediately wipe moisture stains dry with a dry cloth.
Wood can discolor due to exposure to direct sunlight.
Advice: Avoid direct sunlight or use curtains or UV filters to limit discoloration.
Scratches or wear and tear
A varnish is a low-maintenance finish, but it is more susceptible to scratches. It is not (easily) possible to repair scratches and other damage to a varnished finish.
Advice: Use good protection, such as coasters, placemats or a tablecloth.
Stains
Stains are caused by moisture, heat or corrosive substances and are beyond the control of Studio HENK.
Advice: Immediately clean up spilled liquids with a dry cloth to prevent stains.
Walnut wood maintenance advice
Walnut is finished with a transparent lacquer. This can be cleaned with a damp cloth, and then wiped dry with a dry cloth.
- Grease stains can be removed by using a little soap.
- Avoid corrosive cleaning agents or aggressive substances, which can damage the finish.
- Never use abrasive cleaning agents. Wax-containing agents are also strongly discouraged.
