–  Before recoating the lightly sanded substrates, thoroughly clean them of dust, sanding residue and other dirt withsilicone remover -LSW 019 000 A5-. If severely soiled, pre-clean +with slow-drying silicon remover -LVM 020 100 A5-.
Application
Substrate pretreatment (sanding before surfacer coat)
When 2-pack HS Vario surfacer -LGF 786 004 A4- is to be used, bare-metal spots must be primed with 2-pack wash primer -LHV 043 000 A2-.
A uniform substrate without bare metal spots is absolutely essential.

–  Application viscosity 4 mm, +20 °C, DIN 53211
–  The application viscosity of 4 mm at +20 °C is the mixing viscosity for “Compliant” and “HVLP”.
 

Aqua Premium system (painting rims)

–  50 % of additive for Aqua Premium -LVM 035 301- (to be added at material temperature of 20 °C).
 

Aqua Premium system (painting rims)

–  Adjust spray nozzle following manufacturer's instructions to 1.2-1.3 mm for “compliancy”.
–  Adjust spray nozzle following manufacturer's instructions to 1.2-1.3 mm for “HVLP”.
–  Adjust spray pressure following manufacturer's instructions to 2.0 bar for “compliancy”.
–  Adjust atomising pressure following manufacturer's instructions to 0.7 bar for “HVLP”.

–  One application consists of one-and-a-half spray coats (one normal full coat followed by a light coat at greater distance to object).
  Note
The best results are achieved when using an HVLP spray gun with 1.3 mm nozzle.
Blending additive for Aqua Premium -LVM 035 200 A3-/-LVM 035 301 A3- should be added to metallic waterborne base coat -LWG 056 1H7 A1- immediately before application Best results will be achieved if the mixture is applied within one working day.

Drying
Flash-off time before clear coat application:
 

Aqua Premium system (painting rims)

Flash off at +20 °C ambient temperature until matt.
  Note
The best results are achieved when using an HVLP spray gun with 1.3 mm nozzle.
Additive for Aqua Premium -LVM 035 301- should be added to metallic waterborne base coat -LWG 056 1H7 A1 silber- immediately before application. Best results will be achieved if the mixture is applied within one working day.
Ways to reduce flash-off time:
Surface matting can be accelerated by blowing on it with an air diffuser or force drying with infrared radiation or low baking.
It is also possible to blow on it with the spray gun after waiting at least 5 minutes.
Drying time: at least 5 minutes.
  Note
The specified flash-off and drying times depend on the temperature, humidity, air drop speed in the spray booth and the number of coats applied. The surface must, however, first appear completely matt.

Recoating
Recoat with:
2-pack HS clear coat (elasticized)
Special notes
  Note
Blending in with metallic waterborne base coat -LWG 056 1H7 A1- is done in 1 or 2 normal spray coats. Apply blending additive for Aqua Premium -LVM 035 100 A3- to the fade-out area.
Product application
Spraying equipment must be suitable for applying water-based products; manufacturers' instructions must be followed.
The mixing colours in this top coat series can be used only as part of a colour formula. If any mixing colour is applied alone, the results may differ substantially from the description in this technical data sheet.
Cleaning of tools
Rinse with Aquaplus demineralised water -LVW 010 000 A5- before and after use. Then wash out with nitrocellulose thinner -LVE 856 000 A3-.
Waste disposal
Collect liquid water-based waste separately from conventional liquid waste. If the two are mixed, it may be impossible to dispose of the mixture, or at best difficult, and therefore expensive.
