Courtrai Drying Agent Pébéo

Courtrai Drying Agent Pébéo: accelerate drying without compromising paint

The slow drying time is both the strength and the constraint of oil paint. Some pigments, such as blacks, lacquers, and transparent reds, dry particularly slowly, sometimes taking weeks. The Courtrai drying agent is the auxiliary that allows you to take control.

A complete drying, not just on the surface

This is the essential distinction. A poorly formulated drying agent causes the paint to "skin over": the surface hardens while the underneath remains wet, leading to wrinkling and cracking later on. Formulated with zirconium, the Courtrai drying agent acts deeply as well as on the surface. It allows for balanced hardening, even on thick layers and impastos.

A powerful product: to be dosed with precision!

The drying agent is an accelerator, not a medium. It is used in very small quantities, with a few drops added to the paint or medium, never pure and never in excess. Overdosing weakens the paint film, makes it brittle, and can cause cracking over time. The rule is simple: the minimum effective amount.

FAQ

Does it alter colors? No. It is colorless and does not alter light colors — which distinguishes it from more amber drying agents.

What quantity should be used? Very little: a few drops added to the paint or medium are sufficient. The product is powerful, and overdosing harms the strength of the paint film.

Is it used pure? No, never. It is always incorporated into the paint or medium.

Can it be used on all layers? It is mainly used on intermediate layers. Avoid drying an undercoat and not the subsequent layers: this would disrupt the drying balance between layers.
