Do I need to seal my oil painting with anything?

I recently did a wet on wet oil painting and it won't seem to dry. Do I need to seal it with anything? It has been almost 3 days and it is still wet to the touch.Do I need to seal my oil painting with anything?
Oil painting takes six months to dry. After a few days it should be tacky unless you used a lot of mediums or fillers. Thick painting can also smear easily for the first several days. Place your painting somewhere safe. If the painting is thick, try laying it down so the paint does not slide.





After six months, you'll want to seal the painting with varnish.Do I need to seal my oil painting with anything?
Put it in the back window of your car for a day or two. I do that sometimes if I need a painting to dry fast. Don't leave it too long or the paint gets too dry and kind of powdery. Once it is dry you can put on a thin coat of retouch varnish (make sure it is RETOUCH) or a thin layer of liquin to perk it back up. Both of those dry in 30 minutes.


If you use a permanent varnish make sure you wait a full year. Otherwise the paint will crack. Oil paints may dry in a few days, but they take a year to ';set'; even with ';baking'; them in the car.
3 days? Ha! No where near long enough. Three days is good enough to let one layer dry before doing the next, but the painting itself, depending on how thick you work or how much oil is in the paint, could take weeks, months, or longer.





No you don't ';have to'; seal it. But... putting a coat of varnish over an oil will protect it for years. However, an oil painting needs six months to a YEAR to fully dry before doing this. Gives you an idea how long it takes.





The good thing about giving it a coat of varnish is the varnish can be removed and redone. This is assuming the painting is so good that hundreds of years from now someone wants it restored.
Yeah, these guys are right, 3 days is not nearly enough time. Oil paint dries as long as its exposed to air (oxygen). so remember to also leave it out in the open, and definitely not seal it.
