Testing if paint is oil or acrylic is easy. All you need is a brush, a bowl of water, and some paint. Wet your brush in the water and then stroke it over a small area of the paint. If the paint spreads and blends with the water, then it is an oil paint. If the paint forms beads and does not spread, then it is an acrylic paint.

How To Test If Paint Is Oil Or Acrylic

Oil and acrylic paints are both composed of pigment suspended in a liquid carrier. However, the two types of paint differ in their chemical composition and drying mechanisms. Oil paints are made up of organic solvents (such as linseed oil) and pigments, which are ground into a fine powder. The oil paint is then mixed with the solvent, which causes the pigment to disperse in the liquid. As the paint dries, the organic solvents evaporate, leaving the pigment behind

-Paintbrush -Gallon of water -Oil or acrylic paint

  • If it feels oily, the paint is oil
  • Based if it feels like normal paint, the paint is acrylic
  • Take a small amount of paint on your finger
  • Rub it between your fingers

-The consistency of the paint – whether it is thick or thin -How the paint reacts to water -The colour of the paint


Frequently Asked Questions

How Do You Check If Paint Is Oil Or Water Based?

To check if paint is oil or water based, one can drip some paint on to a piece of paper. If the paint spreads out and does not bead up, then it is a water-based paint. If the paint forms beads on the paper, then it is an oil-based paint.

How Do You Tell If Existing Paint Is Oil Or Water Based?

The easiest way to determine if paint is oil or water based is to perform a simple test. Add a few drops of water to the paint and stir it around. If the paint starts to bead up and does not mix with the water, then it is likely an oil-based paint. If the paint mixes with the water and creates a cloudy solution, then it is likely a water-based paint.

How Can You Tell If Paint Is Water-Based Or Oil-Based?

The best way to tell if paint is water-based or oil-based is to read the label. Water-based paints will say “Water-Based” on the label, and oil-based paints will say “Oil-Based.”


To Summarize

Oil and acrylic paints are both pigments suspended in a liquid. However, the difference between the two is that oil-based paints use oil as the suspending agent, while acrylics use water or an acrylic polymer. To test if a paint is oil or acrylic, you can use a simple water droplet test: if the paint droplet spreads out like water, it is an acrylic; if it beads up like oil, it is an oil-based paint.
