How Long Does Oil Paint Take To Dry?

Every time it’s time to repaint a room or our house, I always opt for an oil-based paint. There are many reasons for this. For one, the paint’s result is smoother, and it covers the surface more thoroughly. It is also less prone to shrinkage and hold up well even when frequently touched or disturbed. Lastly, it takes longer to dry. I regard it as an advantage as it gives me more time to finish my work perfectly. However, the amount of time it takes for oil paint to dry can also be a disadvantage.

Why It Takes Time For Oil Paint to Dry

chemical process of oil paint

Oil doesn’t dry the same way as water. Water evaporates. Oil, on the other hand, has to undergo a chemical process called polymerisation so that it can turn into a dry semisolid. This process can only be achieved when oil is exposed to oxygen.

The good thing about oil paint drying slowly is that it becomes malleable. In other words, it enables you to work on the surface for a longer period of time compared to when you use water-based or latex paint. If, for instance, you are painting a design on the room’s wall, you have more freedom to blend color together. You can also add layers of paint on the surface all day while it’s still wet and achieve the exact deepness of color that you like.

Let’s say that you’re done painting a room, and you want the paint to dry. You need to wait longer. In other words, you might not be able to use the room right away. If you want to use the room as soon as possible, you need to be able to manipulate factors like the temperature and humidity inside.

Factors that Affect How Quick Oil Paint Dries

How fast the oil paint dries will have to depend on different factors. These factors include:

Environment

Color and Brand

The drying time may also depend on the color of the paint

The drying time may also depend on the color you are using and the brand of the paint. Titanium white and black dry slower compared to burnt umber. Paints that are made from linseed oil also hardens quicker than those made from poppy and safflower. Walnut oil dries in moderate speed. You can ask the shop assistant about what the paint is made of.

Thickness of Paint

Thickness of paint

Another factor you must consider is the thickness of the paint. The thicker the paint is, the slower it will dry. However, I don’t recommend that you settle for a glaze or thin layer. It’ll dry faster, but you will compromise the result.
