For oil paintings: best let it dry for a longer time (6 months or so), then put dammar varnish over it. The long drying time makes sure you can take off the varnish later, without harming the paint itself.
You can use modge-podge, varnish (make sure it is for acrylics specifically), or use a spray finish to finish an acrylic painting. You can get recommendations at your local art supply store. Always remember to test a finishing medium on a painted paper first, before using it on an actual painting.
It's very easy, acrylic dries very fast, even if you paint thick, so when it's drie then you can just paint over it.

Many artists seal oil paintings with varnish. Other artists use a mixture of varnish and turpentine. Oil paintings can take as long as six months to dry completely.
Use dammar varnish, thinned until it's fluid. Thin it with turpentine. It's important to let the painting dry for a few months first. In this way, the painting becomes restorable. There is some yellowing involved (done by the dammar varnish), but it'll be OK if you don't make a thick layer.
