How we worked it out
Updated as you change the numbers.
- Area = length × width = 24 ft × 22 ft = 528 sq ft.
- Gallons = area × 2 coats ÷ 250 sq ft per gallon.
Method and assumptions
Gallons = area × coats ÷ coverage. A primer coat or a first coat on porous concrete covers less; grinding or etching the floor first is essential for adhesion.
