Primers

All about Primers and why primer is essential

Primer, also known as primer, is the first coat you apply to a surface before you start painting. This layer ensures good adhesion of the paint you will apply afterwards. In addition, a primer levels the surface so that it becomes smooth again and extends the life of the end result. In Automotive, a good car primer is essential to give the paint a tight, durable and professional finish. In addition, without primer the paint does not adhere well and unevenness may remain visible. So it is always important to use a high-quality primer under car paint!

Why is primer essential with automotive paint

Primer is essential with automotive paint because the primer forms a link between the substrate and paint color. By using a primer under car paint you are assured of a serke adhesion. Should there be any unevenness in the substrate, it will be filled immediately so that you can sand the primer to a smooth surface. In short, a high-quality car primer is necessary to use under paint for a finish that is professional and durable.

1K or 2K primer. What's the difference?

If you want to use a primer, you have the choice of a 1K or 2K primer. The difference between these two primers is in their composition. One is based on 1 component, while the other consists of two components. Depending on your requirements regarding a primer, choose the one that suits you. The differences between the two are:

• 1K primer is ready-to-use and fast-drying. This makes the primer ideal for spot repair or small areas. This primer is easy to apply and easy to sand.
• 2K primer mixes with hardener (the second component). This creates a much stronger and more durable layer. A 2K primer is often chosen for professional applications or for larger projects.

Which primer should I use for which substrate?

Which primer you should use depends on which substrate you want it to adhere to. Thus, the material of the surface determines which primer you should use. A good primer is matched to both the surface and the topcoat. The most common substrates with corresponding primer are:

• Metal and iron: an epoxy primer is the most popular primer for this material
• Aluminum and galvanized steel: choose an anti-corrosion etch primer
• Plastic: plastic requires a special plastic primer
• Existing paint or lacquer: universally a 1K or 2K primer can be used for this

Epoxy primer protects metal from rust

Do you want to primer metal for durable adhesion but at the same time want the primer to be rust resistant? An epoxy primer has anti-rust properties that will keep the metal beautiful and rust-free for a long time. Thanks to the epoxy in the anti-rust primer, you benefit from a very strong and durable adhesion. You can apply an epoxy primer to almost any type of metal. This makes an epoxy primer ideal for restoring classic cars, vintage cars or long-term protection of metal parts without painting them.

Anticorrosive primer with etching action for aluminum

You want aluminum to remain beautiful and corrosion-free for a long time. In addition, you want to be assured of durable adhesion of the topcoat. Use an anti-corrosion etch primer for aluminum. This primer is special for aluminum, adheres firmly to the material thanks to its etching action and ensures that forms of corrosion are prevented.

Plastic Primer especially for plastic substrates

Plastic requires a special primer suitable for plastic. A standard primer will not adhere to plastic surfaces. For this, you need a special plastic primer that adheres strongly to all types of plastic. An additional advantage of a primer for plastic is that the primer is flexible and elastic. This makes a plastic primer excellent for bumpers, mirror caps, dashboards, etc.

What color primer should I choose?

Primers are available in various colors such as gray, white, black, reddish-brown and yellow. By choosing the right color primer, you help the topcoat with good coverage. In addition, you avoid having to apply unnecessary layers of paint. As specialists in primers, our advice for the right primer color is:

• Gray primer: neutral and suitable for most final colors
• Black primer: ideal under dark paints such as black, blue or green
• White primer: perfect under light colors such as white, yellow or pastel
• Red-brown primer: often used under red or orange paints
• Yellow primer: suitable for yellow or bright final colors

Air dry primer works quickly and cost-effectively

Don't have a spray booth or drying oven but want to work quickly without incurring high costs? Then an air dry primer is the best primer you can use. A primer that is air-drying does not need to be forced dried. As the name implies, the primer dries by air. This makes this special air dry primer ideal for anyone doing mobile work, spot repair or small repair jobs while maintaining a professional quality.

Wet on Wet primer, faster painting without sanding

This makes a Wet on Wet Primer ideal for situations where you want to work quickly and save time, such as in paint shops or production work. Despite its fast application, a Wet-on-Wet primer still provides good adhesion and coverage. Using this primer increases efficiency without compromising the quality of the end result.
