Disposing of paint may seem like a simple process but it may be more complex than you first thought. It may be tempting to throw out old paint in the garbage but first you will need to know if the paint is oil based or water based.
If the paint you want to be rid of is oil based the law says it is hazardous material and it must be recycled by a firm the is qualified to handle these products. This can vary widely by state and locality. The easiest way to figure this out is to google “where can I recycle old paint near me”? In California this includes many paint stores funded by a tax on every gallon of paint sold. Also local recycling centers usually will take up to ten gallons.
Water based paint can be thrown away if they are fully dry. If you have some water based paints you would like to get rid of without going to a recycling center we have quick way to dry out the paint so that it is suitable to throw away. Buy some of the cheapest cat litter you can get and stir that into the paint. Let it stand a while and once it is good and firm it can be thrown out in the trash. If you are looking at a full gallon of paint you will need to use a five gallon bucket to give yourself room to add enough cat litter.
