–	Application viscosity 4 mm, +20 °C, DIN 53211

Application viscosity 4 mm, gravity-feed spray gun “compliant” and “HVLP”.

2-pack HS premium surfacer

Add 10% VHS hardener at material temperature +20 °C.

HS hardener is not necessary, but up to 10% may be added.

–	If hardener is added, use measuring stick to mix.

2-pack HS premium surfacer

–	Adjust spray nozzle following manufacturer's instructions to 1.6-1.8 mm for “compliancy”.

–	Adjust spray nozzle following manufacturer's instructions to 1.5-1.9 mm for “HVLP”.

–	Adjust spray pressure following manufacturer's instructions to 1.5-3.0 bar for “compliancy”.

–	Adjust atomising pressure following manufacturer's instructions to 0.7 bar for “HVLP”.

–	Three spray coats are necessary to achieve a dry-film thickness of 80-300 µm.

The maximum dry-film thickness for air drying is 300 μm.

The maximum dry-film thickness for force drying is 250 μm.

The maximum dry-film thickness for IR drying is 200 μm.

The maximum dry-film thickness of black paint for IR drying is 180 μm.

The specified thickness for the dry film is 80-200 µm.

2-pack HS premium surfacer

Drying

The material can be sanded after 3-4 hours (film thickness of 80-150 µm and air drying at +20 °C ambient temperature).

If a film thickness of 150-300 µm was applied, allow the material to dry overnight before sanding.

2-pack HS premium surfacer

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

2-pack HS premium surfacer

Force drying at +60 °C material temperature up to 80-150 µm, 25-30 minutes, and 150-250 µm 35-40 minutes.

2-pack HS premium surfacer

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

2-pack HS premium surfacer

Infrared drying (depending on coat thickness) with medium-wave radiant heater, 15-20 minutes and with short-wave radiant heater, 10-15 minutes.

2-pack HS premium surfacer

Further steps

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

2-pack HS premium surfacer

–	Wet sand with P800 to P1000-grain sandpaper.

Recoating

Recoat with:

Waterborne base coat and 2-pack HS clear coat

2-pack HS top coat

Special notes

Elasticization for rigid and semi-rigid plastics:

First mix the base material with 15% elastic additive -ALZ 011 001-. Mixing ratio 3:1 with HS hardeners and no thinner, 4:1 with VHS hardeners and 5% 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 premium filler.

When isolating certain spots - even on problem substrates - the best results are achieved with a medium film thickness of 80-120 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.
