Processing instructions With curing of 5 : 1 and PU hardener DR 4070, adhesion can also be improved on critical substrates.
Particular instructions The product is suitable for top coating PU coloured lacquers and provides improved protection against ring stains. Possible to use as an MDF edge isolation with the addition of 20 - 30 % thinner DV 4900 from the Hesse coloured lacquer systems.
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!

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).
