I am new to using artist oil paint. I used some raw sienna on a figure to see the results. Impressive colors, but after two days the paint is still tacky. I would appreciate some advice on how to use this type paint.
Many thanks

Hi

They do take a while to dry that's true.
The following link may help.

I use Windsor and Newton oils,start by putting your colors on a piece of cardboard and let it set for at least 45 minutes. This will draw out some of the excess oil and speed up drying time. Some people will let the painted figure sit under a light to help dry. I use a hair dryer sometimes on figures and always on vehicles when weathering them.Best regards..........Dale

Use thin layers.

There are easier ways to dry oil paints than just waiting for it to dry. As mentioned above, you can leech some of the linseed oil out of the paint by letting it sit on a piece of cardboard for several hours. Japan dryer is a solvent that can be mixed with some oils which will speed the drying process. In addition, depending on what you are doing with the oils, Turpenoid Light mixed or blended with the oils will speed up drying to several hours or overnight. (I like to use the dot filter method, then I blend with turpenoid light, and usually everything is dry in 12 hours). You can also mix oils with standard mineral spirits, or lacquer thinner (but this is not recommended over enamel paints if you’re using the oils for extensive weathering). Lacquer thinner should be reserved for use over fully cured lacquers or acrylic lacquers. Finally, one of my favorite techniques for getting oils to dry almost instantly is to give them a coat of Testors Dullcoat— this dries the oil almost immediately. However, I always give any oil (or other paint for that matter) a full 24 hours to cure.

I use Windsor and Newton paints. I mix a little of Windsor and Newon's Liquin in with the paint before applying to whatever I'm painting. This helps to thin the paint a little and also it dries overnight.

when I paint flesh tones using oils, I then put the figures into a nice warm airing cupboard in the house and come back to them the following weekend.

Guys-- your recommendations are why we ask questions on this forum. I deeply appreciate your responsiveness and the depth of understanding you have on the subject matter.
