what is the difference between oil based paint and water based paint in terms of ingredients? Is there a certain material that oil based paint contains that water based paint doesn't? Does oil based paint actually contain oil or gas? Why is oil based paint thicker?All help is appreciated!
If you painted latex (water based) paint on top of oil, it will eventually peel.
Set-up your space and get your canvas and paints ready. But you must first have an idea of what subject-matter you want to undertake. I have a full-time job and a Rottweiler-of-an-ex-wife, while pursing an MSW. Painting just seem so out of perspective when dealing with every day drama--but, then when that brush hits that canvas it is so therapeutic. I dig man, I am in the same funk right now. Good luck!
Um, yes, oil based paint contains oil, while water based paint contains water. To create a liquid paint, the pigments and binders have to be mixed into some kind of liquid that will evaporate when the paint dries. Just think of watercolors... the pigment (mixed with a binder) is sold in blocks, and you mix in the water yourself. Then once you paint with it, the water evaporates and you are left with pigment on the paper. There are lots of possibilities for liquid bases for paints... have you ever heard of egg tempera (egg yolk base) or milk paint (milk base)? Both egg yolks and milk contain a liquid that will evaporate, and a binder that will create a structure for the paint. Without a binder, your pigment would just wipe right off the wall once it dries. A water-based paint includes pigment, water (which will evaporate), and a binder (often latex these days). An oil-based paint includes pigment, paint thinner a.k.a. mineral spirits (which will evaporate), and oil as the binder. The thickness of an oil-based paint will depend on how much paint thinner is in it.
