Processing instructions The product can as necessary be mixed at a mixing ratio (by volume) of 5 : 1 with DR 4070 and at a mixing ratio (by volume) of 10 : 1 with DR 4071 to optimise its chemical and mechanical resistance.
Particular instructions The product is also suitable for top coating PU coloured lacquers and provides improved protection against ring stains. Use the dull matt formulation of Hesse PU Multicoat lacquer DE 45000 as a single coating, rather than as a multicoat lacquer!
General instructions on workmanship PU coatings should not be used or dried at material and room temperatures of less than 18 °C and 40 % RH, ideal values: 20 - 25 °C, 50 - 65 % RH. Deviations will result in drying or curing errors. 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 woods must undergo intermediate drying for at least 48 h / 20 °C before overpainting with PU lacquers. If stored correctly (at least 20 °C / room temperature), complete hardening of the coating is achieved after a week.
Please conduct a sample coating under real conditions!

The coating process and the precise treatment parameters are adapted in each case to the respective application and drying conditions and can be found in the customer-specific process descriptions (surface techniques).
