A lacquer/hardener mixture of 5 : 1 with PU Hardener DR 472 is recommended for coating critical substrates. Hardening at 5 : 1 with the PU Hardener DR 4076-0001 also enables direct coating of glass, after adding 5 % glass lacquer additive EL 460-0025 to the lacquer components. Please properly clean the glass surface using Hesse Glass cleaner ZD 101 prior to application.

UNA-Color DB 555-(colour tone) could lead to toning with Hesse PU multicoat lacquer DE 51x(gloss level) (Max. 10 % dilution). In addition the ZD 1 - FT (max. 5 % dilution) colour concentrates may glaze Hesse PU multicoat lacquer DE 51x(gloss level).

“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 or dried at material and room temperatures below 18 °C and 40 % RH, ideal values: 20 - 25 °C and 50 - 65 % RH. Deviations lead to problems with drying and/or curing. To avoid adhesion problems, please gently sand back the PU lacquered surfaces before applying fresh lacquer and apply lacquer to the sanded surfaces as soon as possible. Mixed residues from the previous day must only be used as a 10 - 20 % aggregate in a fresh lacquer/hardener mixture. Old lacquer/hardener mixtures impair the surface quality (adhesion/stability). Freshly bleached wood must be allowed at least 48 h intermediate drying / 20 °C before recoating with PU lacquers. The final hardness of the coating is achieved after one week in correct storage conditions (at least 20 °C room temperature).
Please conduct a sample coating under real conditions!
