Aqua Premium System, Touch-Up System for Three Layer Colors

Preparation

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.

Cleaning

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-".

Special Instructions

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.

Curing Time:

Effect color, 45 to 60 minutes at +20 C (68F)

Solid colors, 90 to 120 minutes at +20 C (68F)

Ventilating/Drying

Choices:

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.

Using the Products

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.

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.
