How much paint does it take to paint a 2400 sq ft house outside?

Question

It's just a big square house. How many gallons? I have no idea

Answer 1

There is a paint calculator at http://www.dunnedwards.com. You have to take into consideration whether you will prime, if you have trim and whether you need two coats of paint.

Answer 2

If it's a big square house, then each side is about 49 feet long. (square root of 2400.)

Other assumptions:
24" roof overhangs all around
No eaves.
8-ft tall walls.

Ignoring windows and doors (subtract those areas - the glass won't be painted.) But you may want a separate color for trim - again, not part of this estimate. Then use 100 square feet per quart.

I would say you have 1632 square feet of paintable area.
(49 + 2) x 4 x 8 = 1632.

Most outdoor surfaces are rough textured, such as stucco. So allow 300 to 350 square feet coverage per gallon. Or, 350-400 sq-ft if smooth wood or siding.

And allow at least 10% extra paint for waste.

I figure you need 6-7 gallons of paint for a rough surface, 5-6 gallons for a smooth surface.

Answer 3

2400 sq ft usually refers to living space inside the house. You will need to measure the exterior walls of the house .Height x width will give you the sq feet of that wall. do that on all 4 sides .Depending on the brand and type of paint you use you can expect to get approx. 350 to 400 sq feet per gallon it will tell you on each can you buy. Heres the kicker paint today generally is not a full gallon also on each can .It is less than a gallon to leave room for tinting.your total amount you will need will depend also on if you have a overhang which needs to me calculated also.For your size house you may need up to 10 gallons with out seeing it nobody can give you an exact amount. Good Luck

Answer 4

A gallon typically does 400 square feet. Measure the area of each wall and add them up to get a total. Subtract the area of doors and windows. Buy extra paint because coverage is worse if the house is dried out from not being painted for a long time or if you are doing a radical color change (which might need a second coat).

Answer 5

It all depends on the brand/manufacturer of the paint and type of paint use choose too use (latex or oil base). All paint cans have the sq. ft. coverage listed on the labels. Go to your local paint store and they should be able to tell you since you know the sq. footage :)

Answer 6

Roughly 7 gallons,,,assuming you can do it in one coat

Answer 7

12 gallons of paint.
