Primer, undercoat, base coat: understanding the differences

Have you ever felt lost in front of the shelves while looking for a "base coat"? You're not alone! Here's a short glossary to help you see things more clearly.

🧱 La couche de fond

This is the product family that prepares the surface. It allows you to mask the old color, even out the surface and ensure good adhesion of the finishing paint.

🧴 L’apprêt (ou apprêt-scellant)

This is the ideal primer for new, porous, or stained surfaces. It "seals" the surface to prevent it from absorbing all the paint.

🎨 La sous-couche

It is specially designed for previously painted surfaces. It ensures a good bond between the old coating and the new paint film.

In summary, skipping this step risks an uneven result and reduced adhesion.
