Fine-grained water-based filler
- Water-based

* The filler must be painted over when used outdoors.
Fast-drying, particularly fine-grained water-based filler for plaster, wood, concrete, and metal. For indoor and outdoor use. Dries quickly. Produces a very smooth surface and can be applied in thin layers if required.

Substrate preparation
The substrate must be clean, dry, grease-free, non-slip, and stable; loose and sandy layers must be removed. Any cement paste or sintered layers on the surface must be removed by sandblasting or mechanical roughening (sanding). Untreated wood and steel must be primed first. Moisture from the rear will impair adhesion.
Coating structure
Maximum layer thickness 2 mm. Before overcoating or wallpapering, sand with 100 - 120 grit.
Processing conditions
During the entire processing and drying time, the material, substrate and air temperature must not fall below 5°C or exceed 30°C.
