At Home

Reduce pollution from paint application by using brushes and rollers instead of sprayers. If you are determined to use a sprayer, use a High-Volume/Low-Pressure (HVLP) spray gun. As the name suggests, a high volume of air at low pressure is used to atomize paint and this reduces overspray and improves transfer efficiency. These guns are capable of a transfer efficiency of 65 percent of greater.

Source green building materials. Choosing lower-impact products for home-improvement projects can reduce toxins in the home and environment, reduce waste and preserve natural resources.

If you have leftover paint, save it for future use. Properly sealed and stored, paint will last for years. Just clean the lip of the can thoroughly, secure the lid tightly, and store the paint can upside down to create a tight seal around the lid and keep the paint fresh until you need it again. If you cannot clean the lip and lid thoroughly, transfer paint to glass jars. Finally, store your paint in a cool place, but where it won't freeze. Even when you can't use it or don't want it anymore, leftover paint can be donated.
