2/3 gallon... so?
the thing that weighs a gallon is a gallon of WATER or a gallon of milk.
That really and truly is highly dependent on the type and quality of the paint.
It depends on the paint. It should say on the can how much it will cover.
Every store has many kinds and qualities of paint. "A gallon of paint" may cost anywhere from $20 - $60 depending on what exactly it is. -
about $7 if you buy the cheap kind but the expensive kind its about $15
1 5 gallon and 3 singles
If the loft has been primed, you will need about a gallon of paint.
Depending on the type of paint but on average it weighs 10 pounds.
Charge by the time spent on the project - not the amount of paint.
2 quarts if you paint all of it. Id buy a gallon to be safe.
