Can Primer Plus be used on a non-absorbent substrate?
Updated: 15.07.2026

Yes, but it is advisable to check the appropriate preparation and adhesion on a non-absorbent substrate.
Detailed answer
Apply Primer Plus evenly with a roller or brush. The objective is not to create puddles, but a continuous film without dry spots. Drying time depends on absorbency, temperature, and ventilation. On a non-absorbent substrate, consumption is usually significantly lower, making the cleanliness and degreasing of the surface even more important. The product coverage on a non-absorbent surface is approximately twice as high.
Common mistakes
- applying a thick layer instead of a thin, grain-tight coat
- sanding without thorough dust removal
- rushing between coats and not allowing adequate drying time
