1.Explanation of the Topic
The drying process of oil paints is influenced by several factors, such as the composition of the paints, the thickness of the applied layers, and the ambient temperature and humidity. Oil paints dry through a process of oxidation, where the oil in the paint reacts with oxygen in the air, causing the paint film to harden.
2. Step-by-step
Choice of Paints: Choose high-quality paints, preferably single-pigment ones (monopigmented), so you can understand the composition of the color and how that pigment will react during drying.
Layer Thickness: Thicker layers take longer to dry. Avoid applying very thick layers to speed up the drying process.
Suitable Environment: Keep your workspace well-ventilated and at a moderate temperature to facilitate drying.
Monitoring: Regularly check the drying progress by gently touching the surface with your fingertip.
Pigments such as natural and synthetic iron oxides dry quickly, while pigments like titanium white and ultramarine blue may take weeks. The choice of colors and the mixtures you make will also influence the drying process.
3. Application Suggestions
When working in layers, wait until the bottom layer is sufficiently dry before applying a subsequent one.
Use fast-drying additives (such as cobalt siccative) to accelerate the drying time of the lower layers.
Tips
Avoid placing paintings in humid areas or spaces with poor air circulation, as this can prolong the drying time.
Thin layers dry faster, so avoid impasto techniques with pure paint.
Reflection on the Topic
Understanding the drying process of oil paints not only improves workflow efficiency but also allows you to explore techniques that depend on controlled drying times, such as glazing and impasto. Patience and knowledge of the variables involved are essential to ensure consistent and durable results in oil painting.
Bonus Tip
Additionally, controlling the drying time of your paints will be useful for urgent deliveries, such as commissions, invitations to short-term exhibitions, improving work efficiency, and applying varnish within a shorter timeframe. There are too many advantages to ignore this process! For this, we recommend cobalt siccative. It’s an additive you can mix at 2% into your base medium. For example, in your 250ml Universal Medium, you can add around 5ml, turning it into a fast-drying medium. It’s as simple as that!
This way, you can ensure drying times of just 1 day across all colors, in a controlled and risk-free manner
for your painting. Fantastic, isn’t it?! 😊.
