Question by NarcisseNoir: Drying time for oil paints?
I painted a plastic mask this morning using oil paints that I thought were acrylic initially. I realized that they were not acrylic about halfway through painting the mask, but I didn’t want to scrap the work I had done on the mask. I used Titanium White and Ivory Black oil paints from a tube, and they were painted in a thin layer, but I forgot to sand the mask down. Is this going to dry/will it dry? I haven’t used oil paints in a good number of years and don’t remember much about drying time. I need it by Thursday night and i need to know whether I’m going to just have to scrap the whole mask and start over without paints…
Thanks for the answers. I’ll probably just have to scrap it if it’s not dry by Thursday afternoon. I’m in a dorm (on an engineering campus) so there’s not much change of me acquiring any mediums to add to the paint. :(

If you didn’t put any medium through them, you’re in for a long wait.
However, if you’re VERY careful, you could try working a little liquin into the paint – that’s a fast-drying oil medium.

Oils take about 24 hours to dry in a open area. Sometimes 48 depending on the humidity.
i dont know what type of paint your using but here.
Linseed oil is made from the seeds of the flax plant. It adds gloss and transparency to paints and is available in several forms. It dries very thoroughly, making it ideal for under painting and initial layers in a painting. Refined linseed oil is a popular, all-purpose, pale to light yellow oil which dries withing three to five days.
Cold-pressed linseed oil dries slightly faster than refined linseed oil and is considered to be the best quality linseed oil.
Stand oil is a thicker processed form of linseed oil, with a slower drying time (about a week to be dry to the touch, though it’ll remain tacky for some time).
You mentioned you didn’t sand the mask…. did you mean it was on plaster? On plastic, it will probably not dry very effectively because it isn’t porous. Even if it dries, it may not adhere very well.
If it’s on plaster, you have a better chance because the plaster will absorb the oil from the paint at the same time the surface dries. If you have a warm place to put the painted mask (not a hot oven or such), but even above a refrigerator, near a warm window, etc., it will speed the drying time considerably. It might get dry enough, depending on your purpose. You didn’t say if you planned to use it as decoration, or wear it.
If it seems dry to the touch, you can surface-dry it using “retouch varnish” spray in two thin coats. This is a varnish that allows the surface to dry, while still enabling enough evaporation of the underlying paint. I’m not sure what effect this would have on plastic.
If you painted on plastic, you could probably wipe the paint off with a soft rag (mineral spirits for any that is stubborn). Wash thoroughly with an oil-dispersing detergent like Dawn liquid. Dry, then paint with acrylic paint as you originally intended.
