Processing instructions For coating critical substrates we recommend a curing of the lacquer/hardener mixture of 5 : 1 with PU Hardener DR 4070.
Particular instructions Please do not use the dull matt adjustment of PU Sun-Blocker DE 42950 as a Multicoat lacquer, but only as a 1-coat finish! The product is suitable for top coating on UNA-COLOR DB 45245-(colour tone) and provides excellent ring-resistance. Pre-priming is possible depending on the desired surface and substrate, for example using PU Basecoat DG 4716, PU Basecoat DG 4717 or NOVA-PUR Basecoat DG 4734.
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!
