Which primer do you choose for which project?
This is how you choose the right base coat for your painting project.
A good painting job starts with a primer, or base coat. This layer ensures better adhesion, even absorption of the paint, and a durable end result, especially on new, porous, or difficult-to-paint surfaces.
Primer for walls
Primer Muur is a water-based, insulating primer specially developed for interior walls such as plaster, plasterboard, masonry, and concrete. This primer reduces and evens out the absorption of the substrate, allowing the paint to dry evenly and cover better. Moreover, it ensures better adhesion of the wall paint and prevents stains or colour differences in the finish coat.
Primer Muur Buiten is designed for outdoor applications and is ideal for facades and other exposed exterior surfaces. This primer acts as a strong adhesion bridge on substrates such as brick, concrete, and existing paint layers. By regulating absorption and improving adhesion, Primer Muur Buiten ensures that the top coat is applied evenly and is more resistant to weather influences.
Primer for wood, metal, and smooth surfaces
Omni Hydro is a water-based one-pot system that serves as a powerful primer and multifunctional base coat for various substrates. It has a hard, easily sandable film with excellent water and water vapor resistance, ensuring a durable substrate for indoor and outdoor varnishes and paints. Omni Hydro is ideal for woodwork, acts as an adhesion bridge on old paint or varnish layers, and can even be applied to smooth materials such as PVC, polyester, polycarbonate, and wall tiles, as well as to metals such as steel, aluminum, copper, and galvanized steel.

Primer for powdery or weak substrates
Primer Fixatie is a transparent impregnating layer specially developed to strengthen loose and powdery substrates. It penetrates deep into the substrate and binds loose dust particles, making the surface firm and stable again. This primer is ideal for old walls, concrete, masonry, and other substrates with questionable or weakened adhesion. By first fixing the substrate, you create a reliable base on which subsequent layers of paint adhere well and prevent problems such as flaking or uneven coverage.
How do you choose the right primer?
Step 1: determine the material of your substrate
- Wall? Choose Primer Muur or Primer Muur Buiten.
- Wood? Go for Omni Hydro.
- Weak wall? Use Primer Fixatie.
Step 2: look at the condition of the substrate
New or highly absorbent surfaces always need a primer. Has the substrate been there for a long time or is it dirty/powdery? Then a fixation or insulating primer is extra important.
Step 3: match your topcoat
Use a base coat that matches the paint you are going to use for optimal adhesion; water-based primers, for example, combine best with water-based topcoats.
