How Many Gallons of Paint Do I Need?
If you’re preparing to paint the interior of your home, make sure to get enough paint to cover your walls with a bit leftover for touch-ups.
But unfortunately, getting the correct amount of paint isn’t always a simple calculation. Instead, there are some key factors you must keep in mind.
The current color of the wall – If your walls are dark, it will take you more paint to adequately cover them. You can help cut down on the number of coats by using paint with a built-in primer.
Color and brand of paint – Darker colors tend to cover the wall better and require fewer coats. But the paint brand also makes a difference as some brands provide better coverage.
Paint vs. paint with primer – A paint with a built-in primer will reduce the number of coats you’ll need to put on the wall.
With all that in mind, it will most likely take two coats of paint to achieve adequate coverage. In some cases, it will take three.
So, if one gallon of paint covers 400 sq ft of the wall with one coat, it covers 200 sq ft with two coats of paint.
How much paint do I need for a 12 x 12 room?
To cover a 12 x 12 room with two coats of paint, you’ll need one gallon. Even then, you should end up with a bit leftover.
If you are covering your walls with three coats of paint, you’ll need a little over a gallon.
How much paint do I need for a 10 x 10 room?
If you’re painting a 10 x 10 room, go for a gallon of paint- you’ll have enough to add 2-3 coats on your walls.
