Grad's reponses to the most common questions
To keep your terrace looking great and in good condition, it is important to clean it twice a year, once in autumn and once in spring!
This will ensure that your wood is in good condition and is not slippery.
A few tips to follow to properly maintain your terrace:
- High-pressure cleaners are not allowed (risk of damaging the wood fibre and creating splinters); preferably use a brush and follow the same direction as the wood fibres (as opposed to an industrial-type single disc floor cleaner).
- Use specialised wood cleaning products. We have created a specific range of wood cleaning products.
- For easy cleaning, we recommend the environmentally friendly G-clean (with black soap).
- For more thorough cleaning (or for a dirtier terrace) choose D-clean which is stronger but also more aggressive towards plants.
- If you want to remove the grey from your terrace decking, the D-New can help you remove the grey layer that forms on the wooden boards due to exposure to UV rays. Attention! The original colour tone will not be restored.
- To preserve the original wood colour preserve the original wood colour of your terrace, we recommend using high-quality saturation agents, which have been adapted for each type of wood.

- Terrace on hard ground: our entire range is ideally suited for such structures.
If the terrace serves as an access to your house with a lot of traffic, we recommend that you avoid wood that is too soft (such as Accoya® or Thermo-pine).
- Terrace on posts: Kebony® and Thermo-ash are the wood types best suited to terraces on posts. Both have the necessary density to withstand the impact of outdoor furniture and daily use.
- Terrace on sealed surfaces: avoid unstable wood types such as Cumaru, Bangkirai or Robinia that require additional support. Wood composites, on the other hand, are very suitable as are all types of wood with added stability (thermally treated wood, Accoya®, Kebony®…)
- Balcony extension: Kebony® and Thermo-ash both have the necessary density to withstand the impact of outdoor furniture and daily use.
- Swimming pool border: Accoya® and Thermo-pine are well suited for swimming pools. Thanks to their low density, they are very barefoot-friendly, even on high-temperature days, and there is no risk of splinters.
A horizontal piece of wood is subject to exposure to different weather conditions every season, which presents a real challenge for this material. Constant fluctuations in temperature and humidity test the hygroscopic properties of the wood and cause it to constantly change shape.

- Variety of styles and prices
Over the last decade, wooden constructions, and especially wooden terraces, have become increasingly popular. As a result, remarkable progress has been made in the area of wood treatment.
In contrast to the traditional approach which involved the systematic use of chemical biocides, new approaches are now focused on environmentally-friendly treatments. None of the new-generation woods present any problems related to toxicity or recycling. Some wood types even have the famous American MBDC Cradle to Cradle quality label, which guarantees the recyclability of the products. The “gold” level of the label rewards products that “promote the preservation of resources for humanity”.
These technologies, which are already widely used in Scandinavian countries, Germany and Switzerland, fall into three categories:
