How oil paints behave ?

in Painting

Oil paint has a creamy, smooth consistency right out of the tube. Sometimes the paint is denser in consistency — titanium white is one example — but you can use most paints right out of the tube. For ease of use and creating thin layers, use a combination of solvent and medium to modify the paint. The solvent dilutes the paint, and the medium adds oil back into the paint to achieve a creamy consistency and bind the pigment particles.

You're likely to notice how slowly your paint is drying. The drying time for a color varies depending on how thick the paint is, how much solvent you used, and how much medium you added. You can also adjust the drying time by using substances specially made to decrease the drying time of your paints.

The slow drying time of oil takes some getting used to. Keep in mind that the slow drying time ensures that your painting is curing properly. Oil paint doesn't dry the way that most people think of things drying, by evaporation of liquid. Oil paint dries through the chemical process of curing. The paint develops a skin of dry surface initially, but the paint itself takes quite some time — maybe months — to dry completely. The process of curing also creates a hard film of dried linseed oil on the surface of the painting. This protects the painting and ensures that it will last for many, many years.

Here are some tips on caring for your tubes of paint:

  • If a tube springs a leak along its side, you can save it by wrapping it in heavy-duty aluminum foil. When you're making such a mess with it that you want to pitch the whole thing, go get a new tube.
  • If you have lost or broken caps, you can again use foil to keep the paint from setting up in the tube. In the end, you may have to throw it away. Whenever you discard a tube of paint, keep the cap for these types of problems.
  • Keep the openings of the tubes clean. Wipe them off with a paper towel to keep hard, dried paint from gumming up the threads of the screw top. Clean out the lid in the same way so that it fits back on tightly. Keep a set of pliers in your paint box for paint tubes that are difficult to open. That should keep you from twisting the tube so much that the tube breaks from the stress.
  • One last thing, and maybe it goes without saying: Never use your teeth to open a tube of paint!
