Volkswagen Golf Service & Repair Manual: Aqua Premium blending system
| Blending additive for Aqua Premium -LVM 035 100 A3- |
| To attain visually perfect colour transition in blending
area or to adjacent parts such as wings or doors. |
| Surfaces coated with primer or surfacer (2-pack HS surfacer) |
| For plastic surfaces, substrates isolated with 2-pack primer
surfacer for plastics -LKF 696 009 A2-/-LKF 696 040 A2- |
| See special notes

|
|
|
| – |
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 using orbital sander with P500-grade paper and dust
collector or wet sand using P800 to P1000-grade waterproof
paper. |
|
|
|
| – |
An extensive section of the adjacent area or parts
surrounding the repair area must be thoroughly but lightly
sanded with P1000 to P3000-grade sandpaper or an emery pad (e.g.
ultrafine). Use an emery pad to sand swage lines, edges or
door-handle recesses during preparation work. |
|
|
|
| – |
Before recoating, use a suitable cleaning agent to ensure a
clean surface free of residues. |
| – |
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. |
| Areas sanded to bare metal must be isolated with 1-pack wash
primer -LVM 044 007 A2-/-LVM 044 171 A2-. Bare metal spots must
not be larger than 5.0 cm in diameter. |
| If 2-pack HS surfacer is used, bare metal spots must be
isolated with 2-pack wash primer -LHV 043 000 A2- or 1-pack wash
primer -LVM 044 007 A2-/-LVM 044 171 A2-. |

| Application, repair procedure |
| Blending in within the surface, e.g. side panel: |

Preparing substrate
→ Anchor. |
|
|
|
| – |
Apply one or two full coats of blending additive for Aqua
Premium -LVM 035 100 A3- at normal spraying pressure in the
blending area surrounding the repair. |
|
|
|
| – |
The first spray coat of the mixed waterborne base coat is
applied from the repair area to the edge of the wet blending
additive. Half of the effect or finish spray coat is applied
immediately over the wet blending additive at a greater spraying
distance. |
Note
| When doing this, ensure that the blending area is larger
than the repair area and covers the wet blending additive for
Aqua Premium -LVM 035 100 A3-. |
|
|
|
| – |
After flashing-off, apply a coat of 2-pack HS clear coat to
the entire repair area. |
Note
| 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. |
|
|
|
| Blending in very small damage, e.g. Clever Repair: |
| – |
Preparing substrate
→ Anchor. |
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. |
| Method »b« (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 needed). |
| Use the Aqua premium measuring stick for Clever Repair to
adjust the correct mixture. |
|
|
|
| – |
Depending on colour and opacity, this mixture is applied in
3 to 5 light spray coats with reduced pressure (0.8 to 1.5 bar)
to the repair area and fade-out area. |
Note
| Ensure that each spray coat is somewhat larger in area and
flashed off until matt. Flash-off may be accelerated by blowing
on it. |
|
|
|
| – |
After an appropriate final flash-off time, 2-pack HS clear
coat can be applied. |
|
|
|
| Blending in 3-stage colours: |
| – |
Preparing substrate
→ Anchor. |
|
|
|
| – |
Apply the base coat mixed with 5% Aqua Premium hardener -LVM
045 000 A1- and, for solid colours 10% Additive for Aqua Premium
-LVM 035 200 A3/LVM 035 300 ...-, or for effect colours mixed
with 20% Additive for Aqua Premium -LVM 035 200 A3/LVM 035 300
...- to the repair area and adjacent blending area until
coverage is opaque. |
Note
| It is recommended to spray a sample object. |
| Use the Aqua Premium measuring stick for three-stage colours
to adjust the correct mixture. |
|
|
|
| – |
Apply one or two full coats of blending additive for Aqua
Premium -LVM 035 100 A3- at normal spraying pressure to the
fade-out area of the base colour or adjacent parts. |
| – |
Paint should now be applied from the fade-out area towards
the repair area. That means, apply the first coat of effect
paint from the fade-out area towards the blending additive for
Aqua Premium -LVM 035 100 A3- (“wet-on-wet”). |
|
|
|
| – |
Then apply the next coat of effect paint towards the repair
area. |
| – |
It is necessary to apply 2 to 3 additional spray coats of
some effect paints to match the effect. Normal spray coats are
applied “wet-on-wet” without intermediate flash-off. |
Note
| It is recommended that all coats, starting with the first
coat, are applied from the furthest blending area to the base
colour in the repair area. This way, all subsequent coats remain
within the previous coat to avoid visible edges or shadows. |
| To make it easier to evaluate the effect, it is recommended
to spray a sample object before every spray coat application. |
|
|
|
| – |
After flashing-off, apply a coat of 2-pack HS clear coat to
the entire repair area. |
Note
| 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. |
| The use of stationary air diffusers or force drying, e.g.
low baking, for efficient flash-off and drying processes is
recommended. |
| 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. |
| A respirator mask must be worn when applying water-based
products. |
