Free delivery · The general rule of thumb is one gallon per 400 square feet. Typically, a gallon of paint covers between 350 and 400 square feet, so a gallon of paint is enough to cover a small space like a bathroom. Depending on the number of coats you intend to paint, the average amount for a normal-sized room is one to two gallons of paint. To be more precise, refer to the manufacturer's recommendations on the label.
McCormick Paints recommends one gallon of paint for every 300 square feet of interior. For an easy reference, you can use our paint calculator. Although they're the same size as a regular paint can, most primers only cover 200 to 300 square feet, so a gallon of primer doesn't reach a gallon of paint. Paint is expensive and you shouldn't buy it in excess (paint stores won't refund a gallon of paint already dyed)).
To determine how much paint you'll need for your painting project, you'll need a measuring tape and maybe a calculator, depending on your math skills. We all know that priming is generally recommended to be applied to walls before painting, but it can be tempting to skip this step. But it can often make even the most experienced DIYers wonder: “How much paint do I need? Knowing the right paint coverage to get the job done can ensure that any DIY project is completed on time, on budget, and with the minimum hassle needed. When painting a bedroom or any room, you must also take into account the primer paint and molding, and if you need to freshen it up, you can include the ceiling in the calculation.
In the example above, you would divide 420 square feet of wall area by 300 to get 1.4, so you'll need 2 gallons of primer. Many people pull their arm away in the last part of the sweep, creating an irregular spray and a build-up of paint in the middle. For example, if you know that you are going to cover a dark wall with a light-colored paint, you will probably want to apply a second coat, even after applying the primer. It paints in good condition on 80% of the surface, but in some places in the front of the house (where it is most exposed to the sun), the paint now has an almost copper color.
If you plan to paint over a room with dark or brightly colored paint, you may need several coats of paint to get the color intensity you want. In this way, much more paint is used directly in the place where it is sprayed and a weak and irregular layer is left at the edges of the spray fan. Calculating the right amount of paint to finish your room is very important for a smooth project, from start to finish. Paint coverage is very important because an insufficient amount of paint equates to bare spots or the old color seen through them. You should take into account the size of the room, the condition of the walls, any drastic color changes and the type of paint you choose.
