Frequently Asked Questions

How does the Accent Wall Calculator work?
It calculates gross wall area, subtracts the entered area of doors and windows, applies the selected number of coats and waste allowance, then estimates paint quantity and project cost.
Should I subtract doors and windows?
Yes. Enter the combined square footage of openings that will not be painted. Leave the value at zero when the entire wall surface will be painted.
Does the calculator round paint up to full cans?
The calculator shows the estimated paint quantity as a decimal so the calculation remains transparent. Purchase quantities depend on the container sizes sold by the selected manufacturer.
How many coats should an accent wall need?
Two coats are common, but coverage can vary with color change, paint quality, surface porosity, primer, application method and the condition of the existing wall.
Does the estimate include primer, trim or wall repairs?
No. Add primer, masking materials, repairs, specialty finishes, tools, trim work, taxes and contractor minimum charges separately when they apply.
