Cleaning:
The substrate must be thoroughly cleaned to remove dirt, oil, grease, dust, and other contaminants. This can be done by sweeping, mopping, and, if necessary, using high-pressure cleaners or special cleaning agents.
Drying:
The floor must be completely dry before the primer is applied. Ensure that no moisture is trapped in the substrate, as this can impair adhesion.
Surface inspection:
Check the floor for cracks, holes, or other damage. These should be repaired to ensure an even coating with the primer.
Dust removal:
After sanding (if necessary), the floor should be thoroughly dusted again to ensure that no dust particles impair the adhesion of the new coating.
This careful preparation ensures that the primer adheres optimally and retains its effectiveness over a longer period of time.
