Processing instructions At a mixing ratio (by volume) 5 : 1 with PU Hardener DR 4071, then PU Multicoat lacquer DE 4503x(gloss level), with the addition of 30 % thinner, is suitable for applying lacquer to wenge.
Particular instructions The dull matt formulation of this PU Multicoat lacquer means it must not be used as a build-up lacquer, but rather only as a single coating on top of the next higher degree of gloss in the same range or on appropriate primers. For use as MDF edge sealant beneath coloured coating systems, prepare the mixture with 20 - 30 % DV 4900 thinner and apply an additional coat on the same day following prior sanding with grit 320. This product can be used as a top coat on PU coloured lacquers in order to create an improved ring stain resistance.
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!
