Processing instructions Sanding of the basecoat with 400 - 600 grit / dust removal. Work the hardener in well, then use water (around 20 %) to adjust the spray viscosity to 20 - 25” (DIN 4 mm). The hardener must always be added before thinning! Never store product mixed with hardener in closed containers. Only ever apply 1 coat of at most 120 g/m² in one operation. Do not apply several thin coats with brief intermediate drying, as may be common with other high gloss systems. Drying of the first coat until application of the subsequent:: 5 - 6 h at 20 °C room temperature and with adequate air circulation. Recoatability: with itself following proper sanding. Clean tools with water. For removal of dried lacquer residues use Hesse HYDRO Cleaning agent HV 6917. In case of combined coatings (HYDRO- and solvent based lacquers) rinse application tools with Hesse HYDRO Reversing agent HV 6904.
Particular instructions Also suitable for top-coating on coloured HYDRO surfaces. Pre-priming is possible, depending on the desired surface and the substrate material, e.g. with HDG 5407 and by request also on various PU systems. HYDRO-PU Multicoat lacquers and top coats are optimised for use on 2-coat hydro systems. Clean tools with water. For removal of dried lacquer residues use Hesse HYDRO Cleaning agent HV 6917. In case of combined coatings (HYDRO- and solvent based lacquers) rinse application tools with Hesse HYDRO Reversing agent HV 6904.
“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 cured 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!
