Application Instructions

Base Surface

Suitable base surfaces:

• Primed or filled surfaces with Two-Part HS Vario Filler -LGF 786 004 A4-, gray
• Factory or old paint (excluding thermoplastic coatings)

Pre-treatment of base surfaces:

• Thoroughly clean factory- or old paint using Silicone Remover -LSW 019 000 A5-, or beforehand with Silicone Remover, Long -LVM 020 100 A5- if very dirty.

• Dry-sand with rotary sander and dust extraction, P1000-1500 grit.
• Sand spokes, corners and edges by hand with an UltraFine/P3000 sanding pad.

• Before reworking, carefully clean the sanded base surfaces of dust, sanding residue and other dirt with Silicone Remover -LSW 019 000 A5- If very dirty, clean beforehand using Silicone Remover, Long -LVM 020 100 A5-.

Processing

Pretreatment of base surfaces (filler leveling):

• Bare areas must be primed with Two-Part Wash Primer -LHV 043 000 A2- when using Two-Part HS Vario Filler -LGF 786 004 A4-.
• It is essential to have even base surfaces that are free of sanded-through areas.

• Dry-sand with rotary sander and dust extraction, P500 grit.

• Wet-sand with P800-1000 grit sandpaper.

Clear coat on the filler:

• Apply two-part HS clear coat on the sanded filler. Depending on the size of the repair area or if there are many repair areas, it is recommended to apply two-part HS clear coat to the entire rim.

• Apply a preliminary spray application (approximately 20 um).

Forced dry at +60 ºC (140º F) object temperature for 20 to 25 minutes

Clear coat sanding:

• Dry-sand with rotary sander and dust extraction, P1000-1500 grit.
• Sand spokes, corners and edges by hand with an UltraFine/P3000 sanding pad.

Cleaning:

• Before reworking the sanded base surfaces, carefully clean them of dust, sanding residue and other dirt with Silicone Remover -LVM 020 000 A5-

Base paint application "spray application"

The following materials can be used as additives:

• Additive for Aqua Premium -LVM 035 301-

• Processing viscosity 4 mm for +20 ºC (68 ºF), German Industry Standardization 53211
• Processing viscosity 4 mm at +20 ºC (68 ºF) material temperature is the mixing viscosity for "Compliant" and "HVLP".

• Add 50 % Additive for Aqua Premium -LVM 035 301- at +20 ºC (68 ºF)material temperature.

• Set spray nozzle (see manufacturer's information): "Compliant" 1.2 to 1.3 mm.

Set spray nozzle (see manufacturer's information): "HVLP" 1.2 to 1.3 mm.

Set spray pressure (see manufacturer's information): "Compliant" to 2.0 bar.

Set atomizing pressure (see manufacturer's information): "HVLP" 0.7 bar.

• One work procedure contains 1.5 spray applications (one normal, preliminary spray application followed by a light spray application while standing back from the object).

Note

• The best results are achieved when using a 1.3 mm HVLP spray gun.
• Additive for Aqua Premium -LVM 035 200 A3-/-LVM 035 301 A3- should be added immediately before applying the Water-Based Metallic Base Paint -LWG 056 1H7 A1-. The best result is achieved when the mixture is used within a working day.

Drying

Evaporating time before clear lacquer application

Ventilate at +20 ºC (68 ºF) room temperature until matted.

Note

• The best results are achieved when using a 1.3 mm HVLP spray gun.
• Additive for Aqua Premium -LVM 035 301- should be added immediately before applying the Water-Based Metallic Base Paint -LWG 056 1H7 A1 silber-. The best result is achieved when the mixture is used within a working day.

The following make it possible to reduce the ventilation time:

• Applying matt to a painted surface can be accelerated by blowing with a spray gun, forced, IR or oven drying.
• Blowing with a spray gun is also possible after waiting at least five minutes.
• The drying time is at least 5 minutes.

Note

The evaporating and drying times specified here depend on the temperature, humidity, air sink speed in the spray booth and the number of spray applications. However, you must wait for painted surface to be applied completely.

Reworking

Can be painted over with:

• Two-part HS clear coat (elasticized)

Special Instructions

Note

Touch-up with Water-Based Metallic Base Paint -LWG 056 1H7 A1- in 1 to 2 normal spray applications. Apply the Touch-Up Additive For Aqua Premium -LVM 035 100 A3- to the run-out area.

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.

Personal Protective Equipment:

• Note the safety data sheets
• Wear the personal protective equipment during application
