DIRECTIONS
Always wear protective clothing and read the safety instructions.
• Stir the pickling paste. Spread the undiluted paste over the surface or the welding joint by
using an acid resistant brush.
• Contact time: 30 min to 2 h. (depending on the type of steel, the kind of welding joint and
the temperature of the environment).
• The pickling process is terminated as soon as the paste turns grey.
• Always rinse abundant with clean water.
• Different optical effects and grey shades can be obtained by varying the pickling time,
concentration or temperature.
• Over-pickling results in sensitivity of the corrosion and harms the passivation process.
