FAQ

How accurate is the gallon estimate? It's as accurate as the coverage number you enter. Use the sq ft per gallon on your can, and buy extra for textured or porous walls or big color changes.

Does it include primer? P01 and P03 prompt you to decide on primer. Calculate it separately, using the primer can's coverage.
