Application
The product is diluted with water depending on the application and the degree of soiling. Optimum effect is achieved at a pH value between 10.0 and 11.5. The product can also be used for neutralisation after the application of acidic paint stripping products. To do this, first remove all dissolved paint residues from the surface with a brush and then spray the surface with water. Then the product is sprayed on at 3 – 5 % by volume to neutralise it. After a short exposure time, rinse with fresh water.
| Application | Concentration | Temperature | Working time |
| Immersion bath | 10 – 50 Vol. % | 50 – 70 °C | 5 – 30 min. |
| Spray and ultrasound | 3 – 15 Vol. % | 50 – 70 °C | 5 – 15 min. |
| Steam and high-pressure cleaning | 1 – 4 Vol. % | > 50 °C | as required |
| manually | 5 – 10 Vol. % | < 50 °C | as required |
