| Particular instructions |
For use as MDF edge sealant beneath coloured lacquer systems, thin the lacquer/hardener mixture with 20 - 30 % thinner. After prior cutting back with grit 320, always coat again on the same day. After sufficient drying and prescribed sanding, Hesse PU Primer DG 4717-0004 can be coated over with, e.g. Hesse PU Multicoat Lacquers DE 4259x(gloss level) or DE 4503x(gloss level).
|
| 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!
