Information on use
Drying |
2 h / 20°C
|
Stackable after |
at least 16 h / 20 °C room temperature with sufficient air circulation.
|
Load bearing after |
48 h / 20°C
|
Surface preparation |
Clean, well-seasoned wood, or clean, suitable MDF or plywood base, free from oil, grease, wax and silicones. Sanded as prescribed and free from sanding dust. The effect is especially distinctive after the pores are brushed out vigorously.

Finishing |
After light surface sanding, it can be top coated using the same product or with a product like COOL-TOP HE 6509x(gloss level). To further increase its resistance, COOL-NATURA can also be top coated using 2C HYDRO systems, such as HYDRO-PU PRIMO HDE 5400x(gloss level) or PURA-NATURA HDE 54451.
|
Comments on sanding |
The quality and uniformity of the wood sanding are crucial to the final surface finish. Ensure uniformity of the surface and edge sanding! Remove dust properly after sanding.

Processing instructions |
Please stir this material well before use! COOL-NATURA can as necessary be diluted with up to 5 % water directly before processing. One or two coats of COOL-NATURA should be applied onto appropriately prepared wood substrates. The COOL-NATURA lacquer layer should not be sanded through or otherwise damaged when finishing with other HYDRO material (risk of stain formation). Please check the appearance and feel of the finished surface based on a trial coating on the original substrate.
|
Particular instructions |
“A risk assessment was undertaken according to Directive 2014/90/EU, Annex II, Section 3. This coating does not pose a physical risk to health nor a risk to the environment when hardened and dried.”
|
General instructions on workmanship |
When working with HYDRO materials, parts that come into contact with the material must be made from stainless steel. The moisture content should be between 8 - 12 %. Do not apply or dry HYDRO lacquers at material or room temperatures below 18 °C. The ideal humidity for application lies between 55 and 65 %. During the lacquering process, a humidity level that is too low leads to surface defects (such as shrink cracks, etc.). Excessive humidity during the drying phase may drastically lengthen the drying time! In order to avoid adhesion problems, please sand the lacquered surfaces freshly before coating and apply lacquer to the sanded surfaces as soon as possible. When applied to foils, etc., please use a sample coating on the respective substrate to check the adhesion! The ideal complete hardening of lacquered surfaces that have been flashed off is reached at temperatures over 20 °C up to no more than 40 °C. Adequate, draft-free air exchange must be assured. The complete hardening of the lacquer will be reached after one week of proper storage (at least 20 °C room temperature). Woods containing large amounts of natural oils, such as teak, can negatively influence adhesion under certain circumstances. Water-soluble wood ingredients such those in ash and tannins in woods such as oak may cause colour changes and discolourations in the coating. We recommend that you always conduct a sample lacquering to evaluate the colour effect, adhesion and drying process under real conditions!
