| Hardened, solvent-resistant, well-preserved and sanded old
paint or factory paints |
| Surfaces treated with primer or filler |
| Suitable pre-treatment materials: |
| Dependent on the object and base surface in accordance with
the structure recommendations. |
|
|
|
| Pre-treatment of base surfaces: |

|
|
|
| – |
Set spray nozzle (see manufacturer's information):
“Compliant” 1.2 to 1.4 mm. |
| – |
Set spray nozzle (see manufacturer's information): “HVLP”
1.3 to 1.4 mm. |
| – |
Set spray pressure (see manufacturer's information):
“Compliant” to 2.0 to 2.5 bar. |
| – |
Set atomizing pressure (see manufacturer's information):
“HVLP” 0.7 bar. |
|
|
|
| – |
1.5 spray applications are required to get the recommended
dry layer thickness of 50 to 60 µm. |
Note
| When using for minimal damage repairs (clever repair
procedure), the 12.5% Two-Part Thinner, Special -LVM 009 200 A2-
can be replaced with 12.5 % HS Spot Thinner -LVM 006 000 A2-. |
| Do not apply on slanted surfaces. |
| During the spray application process, the first half spray
application should form a thin, preliminary film upon which a
fully-completed spray application can be applied. |
| For less opaque colors, it may be necessary to apply another
spray application after the corresponding ventilation time.
Painting over the two-part HS top coat with same is possible to
do without »intermediate sanding«
when done within 24 hours. |
| The mixing paint in this mixing paint 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. |

|
|
|
| Final drying time with forced drying is a minimum of 5 to 10
minutes. |
|
|
|
| Forced dry at +60 °C (140 °F) object temperature for 15 to
20 minutes |
|
|
|
| Final drying time for IR drying is at least 5 minutes. |
|
|
|
| IR drying of bright colors with short-wave radiators for 5
minutes at 50 % power and then for 10 minutes at 100 % power. |
| IR drying of bright colors with medium-wave radiators for 15
minutes |
| IR drying of dark colors with medium-wave radiators for 12
minutes |
| IR drying of dark colors with short-wave radiators for 12
minutes at 50% power |
Note
| When using a short-wave radiator at 100% power, bubbles or
solvent popping marks could form when reworking dark colors. |
