Drying

The material can be sanded after 3-4 hours (film thickness of 60-150 µm and air drying at +20 °C ambient temperature).

If a film thickness of 150-200 µm was applied, allow the material to dry overnight before sanding.

Final flash-off time with force drying is at least 5-15 minutes.

2-pack HS mixture surfacer

Force drying at +60 °C material temperature, 60-150 µm 30-35 minutes.

Final flash-off time with infrared drying is at least 5-10 minutes.

2-pack HS mixture surfacer

Infrared drying (depending on film thickness): medium-wave radiant heater, 15 minutes and short-wave radiant heater, 10 minutes (dry 2 minutes at 50% power and 8 minutes at 100% power).

Further steps

–	Dry sand using orbital sander with P400 to P500-grain sandpaper and dust collector.

2-pack HS mixture surfacer

–	Wet sand with P800 to P1000-grain sandpaper.

2-pack HS mixture surfacer

Recoating

Recoat with:

Special notes

Elasticization for rigid and semi-rigid plastics:

First mix the base material with 15% elastic additive -ALZ 011 001-.

For “wet-on-wet” application with 2-pack HS hardener, 2:1 or 30% mixture surfacer additive -LZS 811 000 A2-

For “wet-on-wet” application with 2-pack VHS hardener, 3:1 or 40% mixture surfacer additive -LZS 811 000 A2-

Application as “sanding surfacer” with 2-pack HS hardener 3:1 and 10% thinner

Application as “sanding surfacer” with 2-pack VHS hardener 4:1 and 20% thinner

2-pack HS mixture surfacer

The minimum flash-off time before the application of a waterborne base coat increases to 45 minutes at 20+ °C ambient temperature.

2-pack HS mixture surfacer

Force drying (oven drying) increases to 45 minutes when used as a “sanding surfacer”.

Any substrate defects can be treated with 2-pack polyester filler. After drying and intermediate sanding, isolate the filler patches with 2-pack HS mixture surfacer.

When isolating certain spots - even on problem substrates - the best results are achieved with a medium film thickness of 60-120 μm in 2 coats, after either air drying overnight, force drying or infrared drying. With problem substrates, careful pretreatment is imperative, and the surfacer must be applied to the entire surface.

For isolating thermoplastic paint, 2-pack HS Vario surfacer -LGF 786 004 A4-, grey is recommended.

For air drying, a minimum temperature of +8-15 °C and the use of 2-pack HS hardener, extra fast-drying -LHA 009 046 A2- is recommended.
