Geroba Corten steel oxidizer rust accelerator 0.5L

Instructions for use:

First degrease the workpiece thoroughly. Allow the workpiece to dry thoroughly before starting treatment. Then apply Cortensteel Oxidizer undiluted to the surface to be treated. Allow it to take effect.

Caution: no product should be left on a flat work surface! (slanting of the workpiece). After drying, spray again to obtain an even surface. After sufficient rust has formed (after one day), the surface can be carefully rinsed (low pressure) to remove the remaining product. If in doubt, test first on a less visible test surface.
