Raindrop effect

• Ensure that priming foil, laminated chipboard or MDF surfaces are well sanded
• Prime with 1 x 150 - 200 g/m² PU Isolating filler DP 491-9343, mixing ratio (by volume) 4 : 1 with PU Hardener DR 405 and diluted with 10 % PU Thinner DV 490
• Allow to dry for at least 16 h / 20 °C
• Sand at 280 - 320 grit
• Apply 1 x 100 - 150g/m² UNA-COLOR DB 45245-(base tone), mixing ratio 10 : 1 with PU Hardener DR 4070 and diluted with 10 % PU Thinner DV 490
• Allow to dry for 2 h / 20 °C
• and continue without intermediate sanding
• Uniformly apply 1 x water using a cup gun with 2 mm nozzle and low pressure; immediately after that mist each droplet on either side (cup gun with 1.2 - 1.5 mm nozzle) one side light the other side dark, so that the drops appear to be three-dimensional
• For example: 
• • one side with UNA-COLOR DB 45245-102 black
  • Mixing ratio 1 : 5 with PU Thinner DV 490
  • Then harden this mixture of colour lacquer and thinner at a ratio 1 : 1 with PU hardener DR 4070.
  • Rotate the surface by 180°
  • and coat the other side with Hesse Metallic Colour concentrate DZ 4995-99042 silver, diluted at a mixing ratio 1 : 1 with DV 490, or optionally DZ 4995-99211 red, DZ 4995-99212 green, DZ 4995-99210 gold, DZ 4995-99042 silver
  • Store in a horizontal position
  • Allow to dry for at least 16 h / 20 °C
• The best depth effect is achieved by finishing with Brillant lacquer!
• Apply 1 x 100 - 120 g/m² each of DU 45229 PU Acrylic brilliant lacquer, for example, leaving 10 - 60 minutes between coats mixing ratio 2 : 1 with PU Hardener DR 4005 thinned with 40 % PU Thinner DV 4935
• If required, it can be polished to a high gloss after just 24 hours, preferably 72 hours of complete hardening.

• The spray nozzle size and distance from the substrate material affect the size of the droplets.
• This effect can only be achieved on horizontal, flat surfaces (no round edges).
• The surfaces must be stored horizontally.
• Shade each droplet with a reduced spray pressure (0.5 - 1.5 bar) from the side, at as shallow an angle as possible.
• PU lacquers should not be processed and dried at material and room temperatures below 18 °C.
• PU lacquered surfaces should be freshly sanded before finishing to avoid adhesion problems.
• Please conduct a test coating!
