You can purchase paint and spreading tools at an art supply store. Use a “soft body” or “fluid” acrylic paint for best results. You can also mix acrylics in water to change their viscosity (thickness) and make them even more fluid. To thin acrylic paints, add water gradually (don’t add too fast or too much, as you don’t want the paints to be too watery). If you are using oils, you may thin them using a linseed oil or odorless mineral spirits (again, mix in slowly).
Let the canvas sit for 2-3 hours to dry before applying fluid paint to it.
Pouring (applying a generous stream of paint to the canvas) Drizzling (pouring very light stream of paint onto the canvas) Dropping (e. g. , from an eye-dropper) Puddling (Applying a puddle of paint to the canvas and letting it seep over it) Splashing (Projecting paint onto the canvas with enough force to bounce back off of it)
Make sure that your tools are perfectly clean before you start painting. Tools should always be cleaned with warm water and hand soap immediately after use, before paint dries on them. [8] X Research source
Opt for artist grade acrylic paint, which has a higher concentration of pigment than student grade paint. [12] X Research source
As a general rule, paint should not be kept for more than two years. [15] X Research source Paint should be stored in a cool, dry place, but should not be allowed to freeze.
