Overview
What is Galva Filler?
ZN-170 Galva Filler is a two-component polyester filler formulated with special resins for galvanised steel and zinc-coated metals. Zinc surfaces make it difficult for standard polyester fillers to adhere, which over time can show up as blistering, edge lifting and flaking. ZN-170 has been developed to provide maximum adhesion on these demanding substrates and also forms a strong bond with aluminium and its alloys.
Its flexible structure tolerates the stresses caused by impact and vibration on thin galvanised panels, reducing the risk of cracking. Its easy-spreading consistency glides on smoothly with a spreader and leaves a smooth surface; once cured, it sands evenly without clogging the paper. As galvanised steel is widely used in the bodies of today's cars, ZN-170 is one of the workshop's essential products for modern vehicle repairs.
ZN-170 is used as the main filler on galvanised panels and aluminium parts; if necessary, a thin coat of ZN-130 Soft Finishing Filler can be applied for final levelling. For priming the bare galvanised and aluminium areas around the filler, ZN-250 Joker Multi-Purpose Primer, which adheres directly to these substrates, is recommended. For bonnet and roof panels exposed to heat, ZN-160 Aluminium Filler can be considered.

Application
Step-by-step application
The recommended application sequence for a professional result.
- 01
Surface preparation
Remove the paint and abrade the surface with P80–P120 without removing the zinc coating completely. Clean off any white rust (zinc corrosion) and free the surface from grease and dirt with ZN-530 Surface Cleaning Thinner.
- 02
Mixing
Mix with 2–3% BPO hardener by weight, without trapping air, until the colour is uniform.
- 03
Application
Press the first coat firmly onto the substrate to form a thin adhesion coat, then complete the fill at no more than 3 mm per coat. Use the mix within 4–6 min.
- 04
Drying
Ready to sand after 20–30 min at 20 °C, or after 3–5 min with short-wave IR. Curing takes longer at low temperatures.
- 05
Sanding
Shape with P80–P120 and finish with P180–P240. Avoid unnecessarily thinning the zinc coating around the filler.
- 06
Priming
Apply ZN-250 Joker Multi-Purpose Primer, making sure it also covers any bare galvanised and aluminium areas.
Storage and safety
- Store in the closed original packaging at 5–25 °C in a dry, well-ventilated place.
- Shelf life in unopened packaging is typically 12 months; close opened tins tightly after use.
- Keep away from direct sunlight, heat and naked flames. The BPO hardener paste contains organic peroxide: protect it from heat and never dip a spreader contaminated with hardener into the filler tin.
- Work in a well-ventilated area when mixing and sanding; wear gloves, safety goggles and at least an FFP2 dust mask. Always consult the product's Safety Data Sheet (SDS).
