Volkswagen Touran Service Manual: Aqua Premium System, Touch-Up System for Three Layer Colors
Product Description/Objective |
To achieve an optically flawless color shade transition in
the blended area or adjacent parts, for example fender/door. |
For plastic surfaces prime with Glazing Adhesion Promoter -ALO
822 000 10- and rework with elastified Two-part HS filler
(Two-Part Plastic Adhesive Filler -LKF 696 009 A2-/-LKF 696 040
A2-). |
|
|
|
Pre-treatment of base surfaces: |
|
Clean the factory or old paint or two-part HS filler
thoroughly with Silicone Remover -LVM 020 000 A5- or Silicone
Remover, Long -LVM 020 100 A5-. |
|
|
|
|
Sand the repair area with P500-P600 grit sandpaper or
wet-sand with water-resistant P800-1000 sandpaper. |
|
|
|
|
Sand the adjacent area (around the vehicle parts and the
repair area) thoroughly with P1000-3000 sandpaper, only wet
sand. |
Note
If beading, edges or grip recesses are present, use a
sanding pad beforehand. |
|
|
|
|
Clean the entire surface thoroughly with Silicone Remover -LVM
020 000 A5- to remove dust, sanding residue and other dirt. |
|
Wipe off any residual silicone remover with a lint-free
cloth, leaving no streaks. |
|
|
|
|
Allow wet-sanded surfaces and cleaned surfaces to dry
completely. |
When using a dust extraction, use next generation towels
with an effective light adhesive formula to minimize the risk of
chemical or adhesive residue (for example, Dust Cloth
-VAS6177-). Refer to
→ Chapter "Dust Cloth -VAS6177-". |
Insulate sanded-through areas with Two-Part Wash Primer -LHV
043 000 A2- and then fill with Two-Part HS Performance Filler. |
Test spraying on sheet metal is strongly recommended. |
|
|
|
Touching-Up Three Layer Colors: |
Adjusting the touch-up additives: |
|
Adjust the Touch-Up Additive For Aqua Premium -LVM 035 100
A3- with 10 % Aqua Premium Hardener -LVM 045 000 A1-. |
|
|
|
Repair Process, Touch-up the Neighboring Surfaces (for
Example Color Matching Fender/Door) |
|
|
|
|
Apply 1-2 preliminary spray applications of the Touch-Up
Additive For Aqua Premium -LVM 035 100 A3--2-
in the blended area with normal spray pressure on the old
paint/filled surface -1-. |
Note
Pay attention that the blended area is large enough. |
|
|
|
Adjusting the base color: |
|
|
|
|
Apply the primary color shade, adjusted for the 5 % Aqua
Premium Hardener -LVM 045 000 A1- and 10 % Additive For Aqua
Premium -LVM 035 301 A3- for solid colors or 20 % Additive For
Aqua Premium -LVM 035 301 A3- for effect colors and adjusted
base colors -2-, onto the repair
area and on the bordering touch-up area up to the covering
capacity. |
|
While doing so the place the run-out area in the wet
Touch-Up Additive For Aqua Premium -LVM 035 100 A3--1-. |
Note
For large surfaces, at high temperatures as well as low
humidity an addition of up to 10 % Aquaplus Purified Water -LVW
010 000 A5- is possible. |
Effect color, 45 to 60 minutes at +20 C (68F) |
Solid colors, 90 to 120 minutes at +20 C (68F) |
|
|
|
The ventilation time should take place assisted with blowing
devices at 20-40 C (68-104F) until the surface becomes
completely matted. |
Allow 5 to 10 minutes of intermediate drying time then 10 to
15 minute final drying time at 60 to 65 C (140 to 149F). Let
the base color shade cool off before applying the effect. |
Ventilate until the surface becomes completely matted,
without blowing. |
|
|
|
|
After ventilating apply 1 to 2 preliminary spray
applications of the Touch-Up Additive For Aqua Premium -LVM 035
100 A3--1- in the blended area
without hardener. |
|
|
|
Adjusting the effect color: |
|
The effect color is adjusted with 20 % Additive for Aqua
Premium - LVM 035 301 A3-. |
Note
For large surfaces, at high temperatures as well as low
humidity an addition of up to 10 % Aquaplus Purified Water -LVW
010 000 A5- is possible. |
|
|
|
Step 1, Painting the Effect Color (from the Outside Inward) |
|
Apply the effect color from run-out area to the to the new
part -1-. This means it is applied
from the outside toward the inside ("wet-in-wet")
in the Touch-Up Additive For Aqua Premium -LVM 035 100 A3-. |
|
Then if necessary apply the next effect color layer in the
direction of the new part. |
Note
For some effect colors 2 to 3 additional spray applications
are necessary to match the effect. |
|
|
|
Step 2, Painting the Effect Color (from the Outside Inward) |
|
|
|
Step 3, Painting the Effect Color (from the Outside Inward) |
|
|
|
|
After ventilating, apply a two-part HS clear coat
-1- over the entire repair surface. |
Note
Starting with the first spray application, it is recommended
to even out the subsequent repair area/base color spray
applications starting from the touch-up area that is farthest
out. For that reason, the subsequent spray applications should
always be remain inside the previous spray application, in order
to avoid visible contours/shadows. |
While processing the Aqua premium water-based base paint,
the material flow (spray gun trigger) remains completely open. |
The spraying pressure for the effect spray application can
vary between 1.5 and 2.0 bar depending on the size of the
object. |
For additional notes to the drying times refer to the
technical application information. |
Notes for Large Area Applications: |
Use the Additive for Aqua Premium -LVM 035 301 A3- when
applying 3 coat effect colors. |
The addition of up to 10 % Aquaplus Purified Water -LVW 010
000 A5- is recommended for large surfaces, high temperatures and
low humidity. |
For efficient ventilating and drying, stationary blowing
devices or forced drying (for example heated drying) are
recommended. |
The spray devices should be suitable for use with
water-soluble products; see manufacturer's information. |
The Aqua Premium mixing paints can only be used within the
color tone formulas. |
When processing individual mixing paints on their own, major
deviations from the information given in the application
instructions are possible. |
Rinse before and after using with Aquaplus Purified Water -LVW
010 000 A5-. Then rinse with Nitrocellulose Thinner -LVE 856 000
A3-. |
Collect liquid waste from water-soluble products and
separate from liquid waste from conventional products. When
mixing materials, disposal may no longer be possible, which is
difficult and costly. |
