Particular instructions For use as MDF edge sealant under coloured coating systems. Dilute the lacquer/hardener mixture for the PU Multicoat lacquer DE 4252x with 20 - 30 % DV 4900. Apply another coat on the very same day, after prior sanding with grit 320 - 400. This product only has limited suitability for top-coating coloured surfaces. Complete resistance to ring stains is not achieved on account of the slightly abrasive surface texture. For this we recommend the use, for example, of a PU Multicoat lacquer from the DE 4259x(gloss level) range or a PU Multicoat lacquer from the DE 4503x(gloss level) range.
At hardening, mixing 5 : 1 PU hardener DR 4070 with PU Multicoat lacquer DE 4252x(gloss level) increases abrasion resistance and additionally enables use even on bleached surfaces.
General instructions on workmanship

PU lacquers should not be applied or dried at material and room temperatures below 18 °C and 40 % ambient humidity, 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 apply a test coat under real conditions!
