| |
First mix the base material with 15% elastic additive -ALZ
011 001-. Mixing ratio 3:1 with VHS hardeners and 20% thinner,
2:1 with HS hardeners and 20% thinner. |
| |
Any substrate defects can be treated with 2-pack polyester
filler. After drying and intermediate sanding, isolate the
filler patches with 2-pack HS Vario surfacer. |
| |
To achieve an optimal finish on passenger cars, it is
recommended to let the surfacer dry overnight before sanding it. |
| |
Do not apply wet-on-wet on top of thermoplastic factory
finish, and if possible let the surfacer dry overnight before
sanding it. |
| |
A minimum temperature of +15°C is recommended for air
drying. |
Caution
| The flash-off times increase to between 30 and
40 minutes before applying base coats or 2-pack top
coats. |
