DIY spray paint

Step 5 Fill with old paint

If you're like me, you have heaps of old, half-used, miscellaneous cans of paint hiding in storage somewhere. Time to put that paint to good use!

If you are mixing paint make sure you are using like-kinds of paint (latex/acrylic with latex/acrylic and oil paint with oil paint), do not mix oil and latex paints! Mixing dissimilar paints is not advised as it's essentially oil and water. Though, it may produce some interesting results. In fact, ignore my warning, try it. Tell me your results!

Drop your old spray paint marble into the bottle first. then carefully pour your paints into the bottle and fill about 3/4 of the way full. You're going to need a funnel. Since regular paint is quite thick, I diluted my paint with a little water after it was in the bottle. I ad a ratio of about 6:1 paint to water. Experimentation here will produce different results. A thicker paint may not drip as much, but might require more pressure in the bottle (see next step regarding pressurization).

Seal bottle with nozzle cap and shake well to ensure an homogenous mix of paint and water.
