| Instructions for painting rims with metallic waterborne base
coat -LWG 056 1H7 A1-. |
| Recoatable with 2-pack HS clear coat |
Note
| After overspraying with 2-pack HS clear coat, it produces a
high-gloss, weather-resistant finish. |
| Surfaces coated with primer or surfacer 2-pack HS Vario
surfacer -LGF 786 004 A4-, grey |
| Factory paint or old paint (except thermoplastic paint) |
|
|
|

remover -LSW 019 000 A5-. If severely soiled, pre-clean the
paintwork with slow-drying silicone remover -LVM 020 100 A5-. |
|
|
|
| – |
Dry sand using orbital sander with P1000 to P1500-grain
sandpaper and dust collector. |
| – |
Sand spokes, corners and edges by hand using P300-grade
ultrafine emery pad. |
|
|
|
| – |
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-. |
| 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. |
|
|
|
| – |
Dry sand using orbital sander with P500-grain sandpaper and
dust collector. |
|
|
|
| – |
Wet sand with P800 to P1000-grain sandpaper. |
| Clear coat over surfacer: |
| – |
Apply 2-pack HS clear coat to the sanded surfacer. Depending
on the size of the repair area or if there are several repair
areas, it is recommended to apply 2-pack HS clear coat to the
entire rim. |
|
|
|
| – |
Apply a full coat (approx. 20 µm). |
|
|
|
| Force drying at +60 °C material temperature in
20-25 minutes. |
|
|
|
| Sanding before clear coat: |
| – |
Dry sand using orbital sander with P1000 to P1500-grain
sandpaper and dust collector. |

| Base coat application “spray” |
| Materials suitable as additives: |
| Additive for Aqua premium -LVM 035 301- |
|
|
|
| – |
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”. |
|
|
|
| – |
50 % of additive for Aqua Premium -LVM 035 301- (to be added
at material temperature of 20 °C). |
|
|
|
| – |
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. |
|
|
|
| Flash-off time before clear coat application: |
|
|
|
| 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. |
|
|
|
| 2-pack HS clear coat (elasticized) |
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. |
| 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. |
| Rinse with Aquaplus demineralised water -LVW 010 000 A5-
before and after use. Then wash out with nitrocellulose thinner
-LVE 856 000 A3-. |
| 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. |
|

|
| Personal protective equipment: |
| Adhere to the safety data sheet. |
| Wear personal protective equipment during application. |
