Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Required volume = surface area × coats ÷ coverage rate × allowance factor. Containers are rounded up to the entered package size.
FAQ
Concrete Sealer Calculator questions
Why can porous concrete need more sealer?+
Open or weathered surfaces absorb more product than dense, previously sealed concrete.
Should every sealer receive two coats?+
No. Use the product instructions for coat count, spreading rate and recoat timing.
Does this include surface preparation?+
No. Cleaning, repairs, etching or grinding are separate project items.
