| Processing instructions |
The process sequence and the number of coats necessary for the insulating effect should be determined by applying a trial coating to the original wood. Washing the wood beforehand with Hesse Wood soap BZ 850 or Hesse Thinner DV 490 can reduce the amount of work involved. Please note that there may be changes to the colour and expressiveness of the wood as a result. A drying time of 16 h / 20 °C must be adhered to when working with content rich wood species! DG 572-1 can additionally be used on content rich, resinous woods or even on exotic wood species as an isolation sealer for transparent and coloured HYDRO lacquers. It should be noted that DG 572-1 must not be sanded back to the bare wood after drying and the required lacquer sanding. Please also observe the technical information for the respective HYDRO product. Conduct a trial coating on the original wood as necessary.

| Particular instructions |
This product is not suitable for application on bleached surfaces and for coating wengé wood. For use as MDF edge insulation under coloured lacquer systems, prepare the lacquer/hardener mixture with 20 - 30 % DV 494 or DV 4994 thinner. Always apply another coat on the same day, after prior sanding with grit 320 - 400 grit. When used as a flame retardant coating material for seagoing vessels according to SOLAS 74/88 Regulations II-2/3, II-2/5 and II-2/6, in the latest version, IMO Resolution MSC.36(63)-(1994 HSC-Code) 7 and IMO Resolution MSC.97(73)-(2000 HSC-Code) 7, this product may only be combined with other approved and technically suitable products. When used as a flame retardant coating material for seagoing vessels, the maximum total application amount in wet film is 200 g/m².
“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 |
PU lacquers should not be applied and dried at material and room-temperatures below 18 °C and 40 % RH. Ideal values are: 20 - 25 °C, 50 - 65 % RH. Deviations will result in drying or hardening errors. In order to avoid adhesion problems, please sand the PU lacquered surfaces before applying fresh lacquer and apply lacquer to the sanded surfaces as soon as possible. Old lacquer and hardener mixtures affect the surface quality (adhesion/resistance). Freshly bleached substrates must undergo intermediate drying for at least 48 h at 20 °C before coating with suitable PU lacquers. If stored correctly (at least 20 °C room temperature), the final hardness of the coating is achieved after a week.
Please apply a test coat under real conditions!
