Concrete Sealer Calculator
Estimate sealer gallons, containers, and material cost using the product's coverage rate.
Concrete Sealer Calculator
Concrete and paver sealer results
Enter the surface dimensions and the coverage rate from the product label.
What the estimate includes
The calculator multiplies width by length, applies the number of coats, divides by your product's square-foot coverage, and adds waste. It then rounds up to whole containers.
Use the manufacturer's rate instead of a generic average. Broom-finished concrete, exposed aggregate, old slabs, and paver joints can change how much sealer the surface absorbs.
The result is a material estimate. Cleaning, repairs, moisture testing, labor, and professional application are outside this calculation.
Use the calculator for the right surface
For blacktop or asphalt pavement, use the asphalt sealcoat calculator. Its coverage and cost fields are built around asphalt sealer.
Planning a new slab? The concrete calculator estimates cubic yards and bags. For paver preparation, use the paver base calculator.
FAQ
How do I calculate concrete sealer gallons?
Multiply the surface area by the number of coats, divide by the coverage rate on the product label, then add your waste allowance. Coverage varies with the sealer, surface texture, porosity, and application method.
Can I use this calculator for pavers?
Yes. Choose Pavers and enter the coverage rate printed for your paver sealer. Wide joints, textured pavers, and porous materials may use more product than smooth concrete.
Should I use the coverage rate from the first or second coat?
Use the product instructions. Some manufacturers publish different rates for the first and second coat. When the rates differ, calculate each coat separately and add the gallons.
Is asphalt driveway sealer the same product?
No. Asphalt sealcoat is made for asphalt pavement. Concrete and paver sealers use different chemistries and coverage guidance. Use the asphalt sealcoat calculator for blacktop driveways.
