For reasons of time and money, the decision was made to use QuickSpray Supreme W (aromatic with drinking water approval), a 100% polyurea 2-component coating material based on polyurea.

The processing was carried out in 4 steps:

1. The new concrete was roughly plastered to close blowholes and capillaries
2. The surface was sealed pore-tight and impermeable to water vapor using a primer and the adhesion properties have been improved
3. The aromatic polyurea QuickSpray was applied using hot spraying
4. After 24 hours, the QuickCoat-Base Protect (aliphatic) for color stability was also applied by hot spraying

These work steps could be successfully completed in a very short time, regardless of the adverse weather conditions. With the savings from using our polyurea system, the acquisition costs of the high-pressure spraying system were amortized with just this one project.
