How to care for thermally modified ash: extending the service life of natural material
Thermo-modified ash is one of the most reliable and aesthetic materials used for finishing facades, terraces and interiors. It is made from ash that has undergone thermal treatment, which gives the wood improved characteristics: stability, resistance to moisture, insects and temperature changes. But despite its high strength, thermally modified wood needs to be cared for if you want to preserve its impeccable appearance and extend its service life for decades.
What affects the service life of thermally modified ash
Thermo-modified ash is resistant to the main factors of wood destruction, but its durability continues to be affected by weather conditions, mechanical impact and lack of protection from ultraviolet radiation. Among the main factors:
direct sunlight that burns out wood pigments;
constant moisture and stagnant water;
mechanical friction (including shoes, furniture, abrasive dirt);
lack of regular cleaning and maintenance.
The service life of thermally modified ash without treatment can be 10-15 years, but with proper care it increases to 25-30 years or more.
How to properly care for thermally modified ash
If you are wondering how to care for thermally modified ash, start with the basics: regularity. Maintaining cleanliness and timely renewal of protective agents is the key to durability. The care system consists of three stages: cleaning, processing, protection.
1. Cleaning thermally modified wood
Regular cleaning of thermally modified wood is necessary to prevent the accumulation of dust, leaves, dirt and mold. Remove dirt with a soft brush and water. You can use a special product for washing thermally modified wood terraces. Avoid aggressive chemicals and hard brushes so as not to damage the structure of the wood.
Care for thermally modified ash decking is especially important after the autumn-winter period. In the spring, the surface is cleaned, allowed to dry and, if necessary, the protection is renewed.
2. Treatment with protective agents
Natural wood requires regular treatment with oils specially designed for thermally modified wood. These are oils with UV filters that protect the wood from fading, darkening and cracking. Thermally modified ash should be treated 1-2 times a year - in spring and early autumn.
The best thermally modified ash care products are natural plant-based oils designed for outdoor use. They not only protect, but also enhance the natural texture and shade of thermally modified ash.
3. Protection from the external environment
If your terrace or facade is exposed to strong sun, wind and precipitation, consider installing a canopy or visor. This will reduce the load on the material and reduce the frequency of maintenance.
Maintaining a thermally modified ash terrace requires slopes and drainage to prevent stagnation of water. Constant moisture is the main enemy of any wood, even thermally modified ash.
Maintenance of a thermally-treated ash facade Maintenance of a thermally-treated ash facade has its own characteristics. If the facade is under a canopy and is not constantly wet, oil treatment can be carried out less often - once every 2 years. It is important to regularly check the surface for cracks and color changes. Cleaning from dust and insects, including cobwebs, is also included in the mandatory list of procedures.
How to extend the service life of thermally modified ash
To extend the service life, follow a few recommendations:
Clean the wood from dirt at least once a year.
Cover with protective agents selected for the surface type.
Avoid using household chemicals and high-pressure washers.
Inspect for damage.
If necessary, sand and renew the surface locally.
Conclusion
How to extend the service life of thermally modified ash is not only about oils and brushes. It is about respect for the material and careful attention to detail. Regular care of thermally modified wood is a guarantee that your terrace, facade or interior will remain stylish, durable and safe for many years. By choosing thermally modified ash, you have already taken a step towards quality. Maintain this quality - care for it properly.
