Edition 10/2012

Product Description

To achieve an optically flawless color shade transition in the blended area or adjacent parts, e.g. fender or door.

Application Instructions

Base Surface

Suitable base surfaces:

Primed and filled surfaces (two-part HS filler)

Intact old paint

With Two-Part Plastic Adhesive Filler -LKF 696 009 A2-/-LKF 696 040 A2- insulated base surfaces on plastic surfaces

See special instructions. Refer to → Anchor.

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-.

Dry-sand with rotary sander with 500 grit and dust extraction or wet-sand with water-resistant P800-1000 grit sandpaper.

Sand the bordering area/part around the repair area thoroughly with an ultrafine P1000-3000 sanding pad. If beading, edges or grip recesses are present, use a sanding pad beforehand.

Use a suitable cleaning agent before reworking to ensure a clean and residue-free surface.

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-".

Special Instructions

Sanded-through areas must be insulated with One-Part Wash Primer -LVM 044 007 A2-/-LVM 044 171 A2-. The sanded-through areas should not be larger than 5.0 cm in diameter.

When using the two-part HS filler, any bare areas must be insulated with Two-Part Wash Primer -LHV 043 000 A2- or One-Part Wash Primer -LVM 044 007 A2-/-LVM 044 171 A2-.

Processing/Repair Process

Touch-up painting inside surface, e.g. side component:

Pre-treating the base surface → Anchor.

Apply 1 to 2 complete spray applications of the Touch-Up Additive For Aqua Premium -LVM 035 100 A3- with normal pressure in each touch-up area around the repair area.

Apply the first spray application of the adjusted water-based base paint to the repair area up to the edge of the wet touch-up additive. Immediately after that, apply the half effect/finish spray application onto the wet touch-up additive from a distance.

Note

When doing so, make sure that the touch-up area is larger/wider than the repair area and that it lies on the wet Touch-Up Additive For Aqua Premium -LVM 035 100 A3-.

After ventilating, apply a two-part HS clear coat over the entire repair surface.

Note

While processing the Aqua premium water-based base paint, the spray gun material flow/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.

Touching-up minimal damage for example clever repair.

Pre-treating the base surface → Anchor.

Note

The repair/filler area should be kept as small as possible.

Possibility "a":

For most colors, use the adjusted water-based base paint.

Possibility "b" (recommended for colors with a high percentage of metal):

Adjust the Aqua premium water-based base paint in a 1:1 ratio with Touch-Up Additive for Aqua Premium -LVM 035 100 A3- + 10 % Flop Control -LWM 085 386 A2- (Additive For Aqua Premium -LVM 035 200/301 ...- is not required).

Use the Aqua premium measuring stick for clever repair to adjust the mixing ratio.

Depending on the color and covering capacity, apply 3-5 spray applications of this mixture with reduced pressure (0.8-1.5 bar) to the repair area/run-off area.

Note

Make sure that each spray application is performed a little bit further and allowed to ventilate and matt. The drying time can be accelerated by "blowing on" it.

After an appropriate final ventilation time, paint over with two-part HS clear coat.

Touching-up three layer colors:

Pre-treating the base surface → Anchor.

Apply the primary color shade, adjusted for the 5 % Aqua Premium Hardener -LVM 045 000 A1- and 10 % Additive For Aqua Premium -LVM 035 200 A3/LVM 035 300 ...- for solid colors or 20 % Additive For Aqua Premium -LVM 035 200 A3/LVM 035 300 ...- for effect colors, onto the repair area and on the bordering touch-up area up to the covering capacity.

Note

Test spraying on sheet metal is recommended.

Use the Aqua premium measuring stick for 3 coat colors to adjust the mixing ratio.

Observe the drying times.

Apply 1 to 2 complete spray applications of the Touch-Up Additive For Aqua Premium -LVM 035 100 A3- with normal pressure to each base color run-out area or bordering component.

Apply going from the run-out area to the repair area. This means, apply the first effect color spray application in the run-out area to the Touch-Up Additive For Aqua Premium -LVM 035 100 A3- ("wet in wet").

Then paint the next effect color layer near the repair area.

For some effect color, it is necessary to apply 2-3 more spray application to achieve the desired optical effect. Normally, apply spray applications "wet-in-wet" and without intermediate ventilation.

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.

For a better assessment, it is recommended to test spray on sheet metal before every spray application.

After ventilating, apply a two-part HS clear coat over the entire repair surface.

Note

While processing the Aqua premium water-based base paint, the spray gun material flow/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 efficient ventilating and drying, stationary blowing devices or forced drying (e.g. oven drying) are recommended.

Using the Products

The spray devices should be suitable for use with water-soluble products; see manufacturer's information.

The mixing paints in this top coat series 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.

Cleaning the Tools

Rinse before and after using with Aquaplus Purified Water -LVW 010 000 A5-. Then rinse with Nitrocellulose Thinner -LVE 856 000 A3-.

Disposal

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.

Health Protection

Wear a breathing mask when using water-soluble products.
