Particular instructions For use as MDF edge-insulation under coloured coating systems, which dilute the lacquer/hardener mixture for the PU Multicoat lacquer DE 4273x(gloss level) with 20 - 30 % DV 4900. Recoated on the very same day, following sanding beforehand with a grit of 320 - 400. This product only has limited suitability for top-coating coloured surfaces. Complete resistance to metal marking is not achieved on account of the slightly abrasive surface texture. Here we recommend the use e.g. of the PU Multicoat lacquer of the DE 4259x(gloss level) series or the PU Multicoat lacquer of the EN 4503x(gloss level) series.
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).
