Volkswagen Golf Service & Repair Manual: Aqua Premium system, blending system for 2-stage colours
| Product description/objectives |
| To attain visually perfect colour transition in blending
area or to adjacent parts such as wings or doors. |
| |
Prime plastic surfaces with transparent adhesion promoter
-ALO 822 000 10-, and then fill with elasticised 2-pack HS
surfacer. |
|
|
|
| – |
Thoroughly clean factory paint, old paint or 2-pack HS
surfacer with silicone remover -LVM 020 000 A5- or slow-drying
silicone remover -LVM 020 100 A5-. |
|
|
|
| – |
Dry-sand repair area using P500/P600-grade sandpaper, or
wet-sand it using water-proof P800/P1000-grade sandpaper. |
|
|
|
| – |
An extensive section of the adjacent area or (parts
surrounding the repair area) must be lightly wet-sanded with
P1000 to P3000-grade sandpaper. |
 Note
| Use an emery pad to sand swage lines, edges or door-handle
recesses during preparation work. |
|
|
|
| – |
Thoroughly clean the whole surface with silicone remover
-LVM 020 000 A5- to remove any dust, paint residue from sanding
or any other impurities. |
| – |
Wipe off any excess silicone remover with a lint-free cloth,
leaving no streaks. |
|
|
|
| – |
Allow the moisture on substrates which have been wet-sanded
or cleaned to evaporate completely. |
| Tack cloths of the latest generation with an effective
adhesion formula, e.g. duster -VAS 6177-) to minimise the risk
of chemical or sticky residue
→ Chapter. |
| |
Isolate any bare metal surfaces using 2-pack wash primer
-LHV 043 000 A2-, and then apply 2-pack HS Performance surfacer. |
|
|
|
| Repair process, blending into adjacent surfaces (e.g.
colour-matching between wing and door) |
| – |
In the blending area, apply one or two full coats of
blending additive for Aqua Premium -LVM 035 100 A3--2-
at normal spraying pressure onto the old paint/surfaced
substrate -1-. |
Note
| Ensure that the blending area is large enough. |
|
|
|
| – |
Then, apply the first moderate spray pass of base coat
-1- from the blending area into the
wet blending additive -2-. |
|
|
|
| – |
After that, apply a second moderate spray pass
-2- directly without waiting for
any flash-off time to elapse. Always make sure to apply this
spray pass offset towards front relative to the previous spray
pass -1- to ensure a uniform
effect. |
|
|
|
| – |
After blending in, the transition and the remaining surface
-1- must be completed in 1.5 spray
passes (starting at new part) (standard process). |
|
|
|
| – |
After flashing-off, apply a coat of 2-pack HS clear coat
-1- to the entire repair area. |
|
|
|
| Repair process, blending into adjacent surfaces (e.g.
colour-matching between wing and door, alternative method for
solid colours and dark effect colours) |
| – |
In the blending area, apply one or two full coats of
blending additive for Aqua Premium -LVM 035 100 A3--2-
at normal spraying pressure onto the old paint/surfaced
substrate -1-. |
Note
| Ensure that the blending area is large enough. |
|
|
|
| – |
Then, apply the first spray pass of base coat
-3- from the blending area
(starting at new part) up to the boundary of the wet blending
additive -2-. Half of the effect or
finish spray coat is applied immediately over the wet blending
additive -2- at a greater spraying
distance and also towards the new part -1-. |
|
|
|
| – |
After blending in, complete the remaining surfaces with base
coat -1- in 1.5 spray passes
(standard process). |
|
|
|
| – |
After flashing-off, apply a coat of 2-pack HS clear coat
-1- to the entire repair area. |
Note
| |
It is recommended that starting with the first spray pass,
all subsequent spray passes are already matched to the repair
area, starting from the furthest blending area. I.e., all
subsequent spray passes remain within the previous spray pass to
ensure a uniform effect. |
| |
Keep the material flow trigger of the spray gun completely
open while applying Aqua Premium waterborne base coat. |
| |
The spray pressure for the effect coat may be varied between
1.5 and 2.0 bar depending on the size of the object. |
|
|
|
| Repair process, blending into very small damage, e.g. Clever
Repair |
Note
| The repair and/or surfacer area should be kept as small as
possible. |
| |
Ready-to-spray waterborne base coats are used for most
colours. |
| |
Recommended for colours with very high metal content; mix
Aqua premium waterborne base coat and blending additive for Aqua
Premium -LVM 035 100 A3- in a 1:1 ratio with 10% Flop Control
-LWM 085 386 A2- (blending additive for Aqua Premium -LVM 035
200/301- is not required). Use the Aqua premium measuring stick
for the Clever Repair spot repair method. |
| |
Depending on colour and opacity, this mixture is applied to
the repair area and fade-out area in 3 to 5 moderate spray
passes with reduced pressure (0.8 to -1.5 bar). Ensure that each
spray coat is somewhat larger in area and flashed off until
matt. The flash-off time can be accelerated by blowing. |
|
|
|
| – |
The clear coat can be applied after the final flash-off time
has elapsed. |
Note
| |
Keep the material flow trigger of the spray gun completely
open while applying Aqua Premium waterborne base coat. |
| |
The use of stationary air diffusers or force drying, e.g.
low baking, for efficient flash-off and drying processes is
recommended. |
| |
The spray equipment must be suitable for water-based
products. Pay attention to the manufacturer's specifications. |
| |
The Aqua Premium mixture paint 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. |
