Allowance
A small extra percentage helps cover touch-ups, texture and application losses.
Frequently asked questions
Should I subtract windows and doors?
For a closer estimate, use the paintable wall area after subtracting large openings.
How many coats should I use?
That depends on the paint, colour change and surface. Use the number recommended for your project.
Is paint coverage exact?
No. Surface texture, application method and product can change real coverage.
