When working on oil paintings, you will need to dry your paints quickly in order to shorten the painting cycle, but incorrect drying methods can ruin your work. So let's talk about how to make your oil paintings dry quickly and safely ......
Have you ever stepped on these mines to make your oil painting dry quickly ↓ ↓ ↓ ↓
Taking an oil painting out into the sun and giving it a "tanning" session results in accelerated aging and even earlier fading of the painting.
Use too much drying agent, a moment to dry a moment of pleasure, color cracking crematorium.
Use too much linseed oil, resulting in serious yellowing of the color later.
Use acrylic paint starting, drying speed is indeed much faster, but the late screen cracking is also quite fragrant.
If you have not stepped on one, then really congratulations, but if you have stepped on a mine, it is better not to step on it next time. If you need oil painting fast drying, you can still use the following methods to achieve oil painting fast drying.
1
Choose some oil paints with fast drying time.
We all know that the drying time of traditional oil paints ranges from 2-10 days. So when you choose the pigments, you can choose the ones with drying time of about two days, such as: cobalt blue, lead white, manganese blue and manganese purple, ochre and brown. Of course such colors are limited, so you still choose according to the actual situation, you don't need to limit the color choice for fast drying.
The following chart shows the drying schedule of some of the colors, which can be used for reference one or two.
Small expansion
The drying principle of oil paints: traditional oil paints are mainly composed of color pigments and binder dry oil, and the reason why oil paints can be dried is also because the dry oil can be naturally oxidized and naturally cured in the air, which is one of the key factors to determine the drying time of oil paints.
Different compositions of color pigments combine with dry oils to produce different reactions, and its drying time also varies. And about the drying time of dry oil, you can take a look at our previous tweet [After so many years of painting oil, do you know how to choose oil painting dry oil? There is a detailed introduction inside, so I won't repeat it here.

Choose different dry oil to adjust the drying time of pigment.
In the above small expansion, we basically know the drying time of various dry oils, if you need to speed up the drying time of pigment, you can choose the linseed oil with drying time in 4-5 days, but never use too much linseed oil, otherwise it will make the picture color produce an inestimable yellowing phenomenon.
On the contrary, if you need the drying time to be extended, you can choose to use poppy oil, safflower oil, sunflower oil which have a longer drying time of about one week.

Use fast drying oil paints that are different from traditional oil paints.
The drying time of these fast drying oil paints can be kept at 24 hours and the surface is basically dry, which is a must for people who go out sketching, indoor creation and people who like to finish oil painting in a short time.
The carrier used in this type of oil paints is not dry oil, but alkyd resin, in a sense, alkyd resin can also be said to be a modified dry oil. Compared to traditional oil paints with dry oil as the carrier, it dries quickly and is less prone to yellowing.
The fast-drying oil paints with alkyd resin as color carrier are alkyd resin cross-linked into large molecules through a series of reactions and dried into a film. In contrast, the molecular weight of dry oil is low, and the formation of macromolecules has to go through multiple cross-linking steps, so it takes a longer time for the paint film to dry. But the alkyd resin synthesized from dry oil is equivalent to increase the molecular weight of dry oil, and it only needs less cross-linking points to cure into a film. Therefore, the drying time is naturally much faster than that of dry oil.
Its yellowing resistance is due to the fact that this oil-modified polymer resin extracted from vegetable oils such as soybean oil and safflower oil has a relatively small yellowing of the raw material itself, and its yellowing will be further improved by the extraction.
The yellowing of dry oil is determined by its main components, among which, glycerides of unsaturated fatty acids such as linolenic acid and linoleic acid are the main cause of yellowing. The main component of alkyd resin is polyol and polyacid, so it is not easy to yellowing.
Such fast drying oil paints have been available on the market for a long time, and Mr. Lu also has one at home, which is Ocotec fast drying oil paints.
The significant advantage of this fast drying pigment is that it can dry the surface in about 24 hours. After curing, it has good toughness, so it is not easy to crack compared with traditional oil paints.
Its creamy consistency is relatively thin, which makes it easy to blend away when using, without stalling the brush, and the strokes will be smoother.
And its 56-color configuration is also richer, with 40 standard colors + 12 opera colors + 4 metallic, which can provide more choices for everyone.
It is also worth mentioning that its price is also very "people-friendly", 50ML is priced at $ 8, out sketching, easy to carry, 170ML is priced at $ 18, affordable, the amount of money saved. One less take-out order, the road to art and another step forward.
If you are a novice and don't know what color to choose, then this 12-color set is just right. In addition to the 12 daily colors in the set, there are also 3 mediums thoughtfully prepared for you.
If you are not comfortable with the drying speed being too fast, adding some Neomegip solvent-free gel will slow down the drying speed a bit and also increase the smoothness of the paint and reduce brush strokes.
If you want to increase the clarity of the paint you can use New Maroge Soft Gel Medium, which also increases the smoothness of the paint. If you want to increase the glossiness of the colors you can use Ocotec Alkyd Quick Dry Medium, which is a 24-36 hour surface touch dry medium that allows you to control the time and articulate the painting.
Of course, you are welcome to continue to explore ways to speed up the drying of oil paintings other than this article ......
