Technical data sheet

Substrate

Suitable substrates:

Sheet steel, electroplated or roller galvanized sheet steel or aluminium, cleaned, sanded and coated with 2-pack wash primer -LHV 043 000 A2- or 1-pack wash primer -LVM 044 ... A2- and then isolated with 2-pack HS surfacer
Fully cured, solvent-resistant, well-preserved and lightly sanded old paint or original paint
Surfaces prepared with 2-pack polyester filler
Cleaned and sanded UP-GF (fibreglass) surfaces, free of release agents
Caution This filler may not be applied to PVB (acid-curing) surfaces or 1-pack primer (e.g. synthetic resin).

It is also unsuitable for thermoplastic or viscoelastic paint.

To attain optimal corrosion protection, it is recommended to prime remaining rust spots on corners and edges, as well as bare metal with 2-pack wash primer -LHV 043 000 A2- or prime them with 1-pack wash primer -LVM 044 ... A2- and then isolate them with 2-pack HS surfacer.

Substrate pre-treatment:
