Questions
Paint Calculator FAQ
How much area does one gallon of paint cover?
A common planning value is about 350 to 400 square feet per coat, but the label and surface porosity control actual coverage.
Does the calculator include the ceiling?
The wall result does not include it by default. Enable ceiling area when it will use the same paint.
