How to Make Hard Paint Soft Again
- 1). Add water to cover the hardened acrylic, or water-based paint. Add rubbing alcohol, turpentine or paint thinner to oil-based paints.
- 2). Allow the paint and thinning liquid to set for at least 15 minutes. It may take longer for larger, thicker amounts of paint.
- 3). Stir or shake the paint and water, or solvent, to mix them.
- 4). Allow the mixture to set longer if it is still hard, adding water or solvent as needed.
- 5). Repeat as necessary.
