Place. What exactly do you want to paint? Exterior or interior? There are different paints for different places. If the paint has a perfect color and quality but is used for the wrong purpose, it will soon need to be replaced.
Location. Where will the paint be used? Kitchen, a child's room or living room? Depending on the place, you will need to choose the properties.
Properties. Paints have different properties that are important when choosing the right paint for the right location. It can be durable, washable and low-odor.
Brand. Paint consists of resin, carrier, clay, solvents and pigment. The quantity of each ingredient determines the quality of the paint. Reputable brands usually have a good mix of the necessary ingredients to make the paint quality the best possible. Unknown and cheap brands might try to save money on one of the important components. While looking great on the outside, the paint might turn out to be almost useless.
Color. The right color can be chosen depending on your preferences as well as the type of the room the paint is chosen for.
Finish. Flat, eggshell, semi-gloss, high-gloss: the right choice of finish will make the color of your paint as rich or as light as you wish. Some reflect light, some don't. Some are shiny and some aren't.
