Comments

Consumption values are indicative and may vary depending on substrate roughness, temperature and porosity, as well as application-related losses. A typical variation of 20% should be considered.

Depending on substrate conditions (e.g. porosity, roughness), a second primer coat and/or a scratch coat may be required.

Depending on the selected topcoat color (e.g. light or bright colors) and the contrast with the underlying layers, an additional topcoat may be required.
