Particular instructions As necessary, Hesse RAPID-ISO-FILL DP 4764-9343 can be hardened with Hesse PU Hardener DR 4036 to accelerate thorough drying. The open time when hardener is added is 30 minutes / 20 °C! In this paint/hardener combination, we recommend the use of two-component spraying equipment. For MDF substrates: With MDF coatings, you can avoid painting faults and edge breaks if you observe the following: Selection of an MDF quality suitable for the field of application, see manufacturer data on EU standard EN 622-5 pt.4 Test methods EN 317 (requirements on thickness swelling). Ideal panel moisture 5 - 7 %. If possible coat the MDF all around, the backs should at least receive a clear coating. Avoid sharp edges and milling grooves, round-off wherever possible. Coat edges and milling grooves 2 x with primer, do not sand through, if need be, prime again. Thick boards that have been built by gluing together several thinner boards are, due to the variance in tension, susceptible to edge ridging. It is better to select a single MDF board of the appropriate thickness. Panels that have been glued together should always be sanded flat at the edges and colourlessly pre-insulated. Any water introduced by the gluing process must be allowed to evaporate prior to coating. Store filler-coated surfaces in an air conditioned location and apply the final coat in a timely manner.
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!

The coating process and the precise treatment parameters are adapted in each case to the respective application and drying conditions and can be found in the customer-specific process descriptions (surface techniques).
