How Much Paint Do I Need?


User-added image

Do you remember that guy from Math class that said, "When will I ever use Math?"

 

Well today is the day.
Calculating the amount of paint you need is a relatively simple math problem.
 
 
Start by adding the length of each wall.
 
In a 12-foot x 14-foot room the total would be (12+12+14+14) = 52-feet.
Then multiply 52 times the height of the room.
 
In a room with ceiling 8-feet above the floor that would be (52 x 8) = 416 square feet.
Subtract the size of the windows and doors 416 - (9+16) = 391 square feet to be painted.

 
A gallon of paint will cover approximately 400 square feet, so you'll need two gallons to paint two coats on this room.

You'll also want to use the right roller cover to apply your paint.

Great video Pat!

Click here for a post from a few weeks back that discusses, per the manufacturer,  how much each paint and exterior stain we carry covers per gallon

Happy Painting!

Thanks Christine!

After years of quoting approximately 400-square feet per gallon for stains, our manufacturers have now introduced thicker products that fill in knot holes and cracks in deck boards.

These products are so viscous that they only cover approximately 100-square feet per gallon.

Both Behr DeckOver and Rust-oleum Restore are classified as solid color stains.

Typically, stains are considered penetrating sealers which must directly contact the wood or concrete surface to absorb and create a long-lasting surface coating.

So, along with knowing how much paint to purchase, every project should include proper prep to ensure the new coating will last.

The 400 sq ft figure is highly optimistic for general wall and ceiling surfaces, although not unattainable under ideal circumstances: If the wall is very well sealed, of smooth texture, good brushes and rollers are being used , and the color not too far from the existing, then yes, 400 sf is possible. In the real world, a figure in the neighborhood of 300 to 350 would be a better bet.

Some paints do cover better than others, but at the cost of applying a thicker coat. However, a thicker coat translates as less square feet per gallon. Behr Ultra, for example, tends to cover better than Premium Plus, yet has exactly the same amount of titanium dioxide white pigment and shares exactly the same tint formula as Premium Plus. Ultra's metallic Nano particles do not increase blanking ability because their extremely  small nano level size are too small to reflect light.
