Processing instructions When being used as a flame-retardant coating agent for seagoing vessels, the maximum total application amount is 120 g/m².
Particular instructions When used as a flame-retardant coating for ocean-going vessels this product is only compatible with other technically suitable and approved products. For use as MDF edge-insulation under colour lacquer systems, treat the lacquer / hardener mixture with 20 - 30 % Thinner (DV 4900 / DV 490 or DV 4994 / DV 494). When used on bleached woods and artificial veneers, the first basecoat application requires the addition of 50 % ( DV 4994 / DV 494 or DV 4955) in relation to the lacquer/hardener mixture. Always apply another coat on the same day after prior sanding at 320 grit.

“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 applied and dried at material and room-temperatures below 18 °C and 40 % RH. Ideal values are: 20 - 25 °C, 50 - 65 % RH. Deviations will result in drying or hardening errors. 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. Old lacquer and hardener mixtures affect the surface quality (adhesion/resistance). Freshly bleached substrates must undergo intermediate drying for at least 48 h at 20 °C before coating with suitable PU lacquers. If stored correctly (at least 20 °C room temperature), the final hardness of the coating is achieved after a week.
Please apply a test coat under real conditions!
