Frequently asked questions
How many bags of stucco do I need?
Divide net wall area, including your waste allowance, by the listed square feet of coverage per bag. Round up separately for each coat.
Can I estimate only the finish coat?
Yes. Select the coats required for your project. Each selected coat uses the same net wall area and its own bag coverage.
