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. Renovations/repairs on already sealed surfaces: Seal a sample section and check whether the existing substrate could be sealed using UNA-ELITE. After sufficient drying, test the bond of the overall structure! Shake the lacquer well! Press the insert sieve into the pouring hole, fill the lacquer into a suitable paint kettle and work from that! Do not use a mechanical mixer as there is a risk of foam or bubble formation!
Particular instructions Critical substrates such as wood block, on-edge lamellar parquet, floor boards, parquet flooring on underfloor heating, etc. require proper pre-treatment with HG 22 / HG 24 to minimise the risk of lateral bonding. To avoid the possibility of staining, please only renovate parquet flooring, which was previously treated with solvent-based systems, with solvent-based systems again! 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. Shake well before use! Spraying: possible; however the addition of water is required. Personal protective equipment and adherence to the legal guidelines are necessary for spray application!
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.
