It is worth noting that naturally, oil takes longer to dry than another medium. You seldom make the oil paint to dry in a few hours. Therefore, if you want the oil paint dry quicker, then use a different medium such as acrylic polymer. The following tips can cause your oil paint to dry faster than it usually does though not immediately.
1. Pigments within the Paint
Oil paints contain powdered pigments that create the different colours we get. The pigments have unique properties, which determine their drying time, when combined with oil. At the paint tube’s back, you will find the pigment in it and be able to know the kind of pigment that’s responsible for a particular colour.
Generally, earth colours dry much faster than others and are derived from iron oxide. Therefore, try to integrate more of such colours if you’d like the paint to dry faster.
2. Use Thick over Thin Strategy
If you want oil painting to dry faster, paint thin layers underneath the thick ones. Oils usually dry as they absorb oxygen from the air. Therefore, if you put the thick layers at the top and thin layers beneath, the two layers will take the same amount of time to dry unlike if you placed thick layers below the thin ones.
If you did the latter, the upper layer would dry earlier than the lower one, causing a crack in your painting. This will ruin your effort and outcome alike. When you put in thin layers first, they will dry faster and allow you to paint over them.
3. Use Thinning Mediums
Use of thinning mediums accelerates the rate at which your paint dries. For instance, you can try to use odourless solvents, or even other forms quick drying media such as Liquin, Liquin Impasto, and Liquin Original for oil paints. These media create a thinner layer, which is dries faster.
