Do you need to use a primer?

All Fleur colours have excellent adhesion and can be applied directly on any surface without primer. Despite this, in case of high wear surfaces, to add resistance and adhesion, it is advisable to use one of the following primers: apply Universal Primer on non-absorbent surfaces, apply Primer for Wood to even out an absorbing surface; apply Antirust Primer to block the corrosion of a metal object.
