Raindrop effect

Sample process:

Step 1:

• Sand down priming foil, laminated chipboard or MDF surfaces well
• Prime with one coat of 150 - 200 g/m² PU Isolating filler DP 4791-9343 mixing ratio (by volume) 4 :1 with PU Hardener DR 5058 thinned with 10 % PU Thinner DV 4900
• Dry for at least 16 hours at 20°C
• 280 - 320 abrasive grain
• Apply one coat of 100 - 150g/m² of UNA-COLOR DB 45245-(base tone) mixing ratio (by volume) 10 : 1 with PU Hardener DR 4070 thinned with 10 % PU Thinner DV 4900
• Dry for 2 hours at 20 °C
• continue without intermediate sanding

Step 2:

• Apply one coat of water evenly with the cup gun, a 2 mm nozzle and low pressure; immediately afterwards, mist each droplet on one side (cup gun, 1.2 - 1.5 mm nozzle) one side light, other side dark, so that the drops are shown three-dimensionally

Example:
One side with UNA-COLOR DB 45245-102 black mixing ratio (by volume) 1 : 5 with PU Thinner DV 4900
Then harden this mixture of coloured lacquer and Thinner 1 : 1 with PU Hardener DR 4070.
Rotate surface through 180°
Other side with metallic colour concentrate DZ 4995-99042 silver, mixing ratio (by volume) 1 : 1 thinned with PU Thinner DV 4900 or optionally
DZ 4995-99211 red
DZ 4995-99212 green
DZ 4995-99210 gold
DZ 4995-99042 silver
Store horizontally
Dry for at least 16 hours at 20 °C

Step 3:

• The best depth effect is achieved with a top coat of brilliant lacquer!
• Apply two top coats of 100 - 120 g/m² each of FANTASTIC-BRILLANT DU 48799, for example, leaving 10 - 60 minutes between coats mixing ratio (by volume) 4 : 1 with PU Hardener DR 4071 thinned with 20 – 30 % PU Thinner DV 4935
• If required, it can be polished to a high gloss > 48 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!
