Processing instructions	MEGA-PUR can as necessary be mixed at a mixing ratio (by volume) of 5 : 1 with PU Hardener DR 4070 and at a mixing ratio (by volume) of 10 : 1 with PU Hardener DR 4071 to optimise chemical and mechanical resistance.
Particular instructions	This product can only be combined with other approved and technically suitable products when used as flame-retardant coating for seagoing vessels. The maximum wet film application amount when used as a flame-retardant coating for seagoing vessels is 240 g/m². Do not use the extra matt configuration of MEGA-PUR as a Multicoat lacquer, but only as a 1-coat finish on top of the next highest gloss levels in the series or on a matching basecoat! Pre-priming is possible depending on the desired surface and substrate, for instance using Hesse Basecoats DG 572-1, DG 434, DG 534, DG 417 und OPTI-BASE DG 4750. MEGA-PUR Multicoat lacquer is suitable for finishing Hesse UNA-COLOR and FANTASTIC-COLOR and its transparent finish provides excellent metal marking resistance. This operation can also be used in parallel to individually determine the gloss level of the colour lacquer to be applied. The stipulated test certificates relate exclusively to a mixing ratio (by volume) of 10 : 1 with PU Hardener DR 4070. “A risk assessment was undertaken according to Directive 2014/90/EU, Annex II, Section 3. This coating does not pose a physical risk to health nor a risk to the environment when cured and dried.”
General instructions on workmanship	PU lacquers should not be used and dried at product and room temperatures below 18 °C and below 40 % RH , ideal values: 20 -25 °C, 50 - 65 % RH. Deviations lead to problems with drying or, as may apply, hardening. In order to avoid adhesion problems, please sand 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 woods must be dried for at least 48 h / 20 °C before being coated with PU lacquers. If stored correctly (at least 20 °C room temperature), complete hardening of the coating is achieved after a week. Please apply a test coat under real conditions!
