One of the best ways to waste time during a paint project is to forget must-have items and make extra trips to the store. Not only do you spend needless travel time, but you are often forced to press pause on your project until you get the proper materials.
Use a paint calculator to determine how much paint you’ll need. Just measure your room, including walls, doors and windows, and plug the numbers into The Home Depot’s handy online paint calculator. Most paints will indicate the coverage area per gallon, but if you’re not sure, 400 sq. feet per gallon is a good rule of thumb.
