Volkswagen Golf Service & Repair Manual: Aquaplus design and multi-colour painting
| To be able to execute fault-free design and multi-colour
paintwork with Aquaplus non-metallic, metallic and pearl effect
base paint, a number of special features need to be considered,
and some special aids deployed. |
| Where a design is marked out on the base surface (surfacer,
paintwork), no marker pens containing water-soluble inks must be
used, so as to prevent »bleed-through«
into the waterborne base coat. If this is not possible, the
markings must be removed thoroughly using silicone remover -LSW
019 000 A5- immediately after the design has been masked off. |
| Masking the substrate (2-pack HS top coat) |
| You can use commercially available contour/decor fine line
tape and masking tape for masking on 2-pack HS top coats. |
| Masking Aquaplus non-metallic, metallic, pearl effect base
paint |
| Use commercially available contour/decor fine line tape and
masking tape. |
| |
Press contour and masking tapes carefully into place |
| |
If masking wide areas, use masking film (to avoid marks). |
| |
Never leave contour and masking tapes on the surface for
longer than necessary. |
| Drying individual layers of water-based base paint |
| Oven drying is not advisable, as there is a risk of adhesive
being transferred from the contour and masking tapes to the
waterborne base coat. |
| The individual layers of water-based base paint can be dried
using air nozzles or at increased booth temperatures. These are
also the most effective drying methods. |
| The thickness of the individual layers shall not exceed
40 µm. Otherwise the film may be detached when removing the
masking tape, the coverage may be insufficient or issues may
arise during drying. |
| Multi-colour paintwork with insulation layer |
| To prevent »bleed-through« and
colour distortion in the individual colour layers of
multi-colour paintwork systems, it is advisable to insulate the
individual layers with 2-pack clear coat. |
| The 2-pack HS Vario clear coat -L2K 769 K01 A5- cross-linked
with fast-drying 2-pack HS hardener -LHA 021 004 A3- may be used
for this. |
| To attain acceptable drying and coverage, the use of
slower-drying hardeners is not recommended. |
| The insulating layer must be applied only onto the Aquaplus
waterborne base coat. |
| The steps required are set out below based on the example of
a 3-colour multi-colour paintwork system. |
|
|
|
| – |
Apply first colour with Aquaplus waterborne base coat. |
|
|
|
| – |
Dry base coat for at least 5 hours at +20°C. |
|
|
|
| 20 minutes at +20°C and 30 minutes at +60°C |
| Allow to cool sufficiently after drying. |
| – |
Mask contours using commercially available tape or film. |
|
|
|
| – |
Apply a thin, full coat of blending additive for Aquaplus
-LVM 030 000 A2-. |
|
|
|
| – |
Then, allow to flash-off for at least 20 minutes at +20°C. |
|
|
|
| – |
Apply second colour with Aquaplus waterborne base coat. |
|
|
|
| – |
Dry base coat for at least 5 hours at +20°C. |
|
|
|
| 20 minutes at +20°C and 30 minutes at +60°C |
| Allow to cool sufficiently after drying. |
| – |
Mask contours using commercially available tape or film. |
|
|
|
| – |
Apply third colour with Aquaplus waterborne base coat. |
|
|
|
| – |
Allow base coat to flash-off until it is matt. |
|
|
|
| – |
Apply top layer of 2-pack HS clear coat. |
 Note
-
| |
Plastic film should always be used for any necessary
masking, so as to prevent attachment of the already applied
paint layers. |
-
| |
Marks created by masking are eliminated by the
subsequent clear coat application. |
-
| |
For all other parameters relevant to the application
of the specific product refer to the technical data sheet. |
