| Surface preparation |
Professionally laid and prepared parquet or corresponding wooden flooring. The floor must first be sanded back to the bare wood and be dry and free from oil, grease, wax, silicones and sanding dust.

| Processing instructions |
The floor must first be sanded back to the bare wood and be dry and free from oil, grease, wax, silicones and sanding dust. Shake the lacquer well! Add the correct hardener to the organic lacquer container and immediately shake well for 1 - 2 min. Do not mix in the application container. The mixing ratio must also be accurately observed in the case of partial amounts, and the mixture well shaken. Press the strainer into the outlet opening, fill the lacquer / hardener mixture into a suitable application container and work from this! Only use a mixture within the given application time. Never store product mixed with hardening agent in closed containers. Do not use any electrical stirring devices; risk of forming foam or bubbles!
|
| Particular instructions |
Greying may occur on dark woods or stains because of the light milky colour of the products.. In order to reduce the risk of lateral bonding, critical substrates such as wood plaster, edge lamellae, floor boards, parquet on underfloor heating, etc. require an appropriate pretreatment with HG 21 or HG 22. If using particularly tannin-rich woods, we recommend using basecoat HG 22 or HG 24. To avoid the possibility of staining, please only renovate parquet flooring, which was previously treated with solvent-based systems, with solvent-based systems again! Shake the lacquer well! Spraying: possible; however the addition of water is required. When the hardening agent is well worked in, adjust the spraying viscosity with up to 5 % water. Personal protective equipment and adherence to the instructions for the spraying application. Press the strainer into the outlet opening, fill the lacquer / hardener mixture into a suitable application container and work from this! Only use a mixture within the given application time. Never store product mixed with hardening agent in closed containers. Do not use any electrical stirring devices; risk of forming foam or bubbles! Clean work equipment with water. Dried lacquer residue can be removed with Hesse CLEANING-AGENT DV 9. Films or carpets must not be placed on the parquet flooring until it has completely hardened.

| General instructions on workmanship |
The moisture content should be between 8 - 12 %. Please do not use and dry HYDRO lacquers at material and room temperatures below 18 °C. The ideal humidity for painting is between 55 and 65 %. In order to avoid problems with bonding, please sand the lacquered surfaces before applying fresh lacquer and apply lacquer to the sanded surfaces as soon as possible. Woods with a very high wax content such as teak can have a negative effect on bonding in some circumstances. Water-soluble wood contents such as from ash and tannic acid from woods such as oak can initiate changes in colour tones and discolouration in the lacquer. For this reason we recommend a trial lacquering be undertaken as a matter of principle to assess the colour effect, bonding and drying progression under real conditions! Notes on cleaning and care: Please observe the care instructions in accordance with DIN 18356. Wipe parquet with a slightly damp, not wet, cloth. Please use only neutral, silicone-free, salmiac-free and non-abrasive cleaners. Regular care and cleaning with Hesse PROTECT-CLEANER PR 90 and Hesse INTENSIVE-CLEANER PR 91 increases the life of the sealing.
