| Particular instructions |
The brightening effect is only achieved given direct coating onto the wood or onto HYDRO stains, such as positive stains. Only a fresh lacquer / hardener mixture guarantees an optimum brightening effect!
Individual toning is optionally possible with:
up to 10 % DB 45245-(colour tone) or
up to 5 % Colour concentrate ZD 1-(colour tone) or
up to 5 % Colour concentrates CF xx or CPxx (except CP 70xx).
An additional coat can be applied after sufficient drying and proper sanding, for instance using DE 55x(gloss level) or DE 56x(gloss level).
This product must only be combined with other approved and technically suitable products when used as a flame retardant coating material for seagoing vessels according to the latest version of SOLAS 74/88 Reg. II-2/3, II-2/5 and II-2/6, IMO Resolution MSC.36(63)-(1994 HSC-Code) 7 and IMO Resolution MSC.97(73)-(2000 HSC-Code) 7. The maximum application amount in wet film when using this product as a flame retardant coating material for seagoing vessels is 250 g/m².
“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 or dried at material and room temperatures of less than 18 °C and 40 % RH, ideal values: 20 - 25 °C, 50 - 65 % RH. Deviations will result in drying or curing errors. 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 undergo intermediate drying for at least 48 h / 20 °C before overpainting with PU lacquers. If stored correctly (at least 20 °C room temperature), complete hardening of the coating is achieved after a week. Please test the lacquer under real conditions!
