System and application
The primer bonds the base preparation to the next compatible layer.
Tiefengrund is an example of absorbency regulation. Betokontakt is an adhesion primer for suitable poorly absorbent substrates before a compatible gypsum plaster.
Choosing the material
- Wearability and cleanliness of the base
- Absorbency and compatible subsequent coating
- Consumption and drying for the exact product
Limitations and important notes
A primer is not automatically suitable for each stage. The next layer is applied when the base is ready and after the necessary drying according to the instructions.
The technical values are on the page of each specific product along with the official source. Do not apply one norm to the whole group.
