"Wet-in-wet" Use

Ventilation time before applying top coat at +20 ºC (68 ºF) room temperature:

• 15 to 20 minutes up to a maximum of 90 minutes for two-part HS top coat
• 25 to 30 minutes up to a maximum of 90 minutes for water-based base paint
• 30 to 35 minutes up to a maximum of 90 minutes for Aqua premium water-based base paint

Reworking as "wet-in-wet" Filler

Can be painted over with:

• Water-based base paint and two-part HS clear coat
• Two-Part HS Top Coat

Special Instructions

Elastification for rigid and semi-rigid plastics:

• The base material must first be mixed with 15 % Elastic Additive -ALZ 011 001-. 3:1 mixing ratio for VHS hardener and 20% thinner, 2:1 mixing ratio for HS hardener with 20 % thinner.
• Any faults in the base surface can be filled with two-part polyester filling paste. After drying and intermediate sanding, insulate the filler patches with two-part HS vario filler.
• In order to achieve the best surface finish for vehicle painting, we recommend the filler be sanded after it dries over night.
• Do not use the wet-in-wet process on thermoplastic factory paint, and if possible let the filler air-dry overnight before sanding it.
• When air drying, a minimum of +15 ºC (59 ºF) is recommended.

Caution

Allow for a ventilation time of 30 to 40 minutes before applying the base paint/two-part top coat series.

Personal Protective Equipment:

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