A flat surface such as board ensures the paint is evenly dispersed and dried.
Oil paint drying time on wood.
As you can see there are many methods of speeding up drying time for oil paintings.
Artist oil paint on untreated wood will react to the wood and over time the wood will start to rot and deteriorate.
Paints made from linseed oil can speed your painting s drying time significantly and they re easily found at most art supply stores.
Because of this you have much more time to manipulate oil paint on your canvas before it dries.
The amount of oil used in your painting and the oil to color ratio is also a very important factor in the drying time of your paints.
The drying time of oil paints can vary based on the oil which was used.
Dry time depends on ambient temperature access to ventilation how open the wood grain is how absorbent the substrate is and how thick the paint is applied etc.
This is one of the reasons why oil paint is so widely used by artists.
Oil paint is inherently slow drying compared to the other painting mediums such as acrylic watercolor or gouache paints.
Recoat time for oil based paint.
Oil based paint may feel dry two to four hours after it s applied.
Oil based paint is more durable and takes longer to dry than water based paint.
However you would not want to paint on plain wood or metal without good surface preparation and a sealer and primer coat of gesso first.
The less the amount of oil used as in the thinner the paint layer is the faster it will dry.
On a properly prepared wood or metal surface oil paint will dry the same as on canvas.
Oil paint on textured canvas tends to dry more slowly as thicker globs of paint fill the crevices of the canvas.
Look for paints made with linseed oil.
Linseed oil dries faster than walnut oil which itself dries faster than poppy oil.
