How to Use This Calculator
  1. Enter the total concrete surface area in sq ft to be sealed.
  2. Select the sealer type (1–7): acrylic, solvent acrylic, water-based acrylic, penetrating, epoxy, polyurethane, or polyaspartic.
  3. Choose surface texture (1=smooth, 2=broom-finished, 3=stamped/heavy texture) — rougher surfaces absorb more sealer.
  4. Set the number of coats (typically 2; penetrating sealers often need only 1).
  5. Read Total Sealer (gallons) and Total Material Cost to finalize your material purchase.
  6. Note Recoat Interval (years) and Dry Time Between Coats (hrs) for scheduling the application.

What each input means

Surface area (sq ft)
Total concrete surface area to seal.
Sealer type (1-7)
1=acrylic cure&seal, 2=solvent acrylic, 3=water acrylic, 4=penetrating, 5=epoxy, 6=polyurethane, 7=polyaspartic.
Surface texture (1-3)
1 = smooth/troweled, 2 = broom-finished, 3 = stamped/heavy texture.
Number of coats
Most sealers need 2 coats. Penetrating sealers often need just 1.
Waste factor (%)
Material waste from overspray, drips, and roller absorption.

What each result means

Total sealer (gallons)
Gallons of sealer to purchase for all coats plus waste.
Gallons per coat
Sealer needed for a single coat (before waste factor).
Total material cost ($)
Sealer plus solvent/cleanup costs.
Cost per sq ft ($)
Material cost per square foot of sealed area.
Sealer cost ($)
Cost of the sealer product alone.
Xylene / solvent (gal)
Cleanup solvent needed for solvent-based products (0 for water-based).
Recoat interval (years)
Typical lifespan before re-sealing is needed.
Dry time between coats (hrs)
Minimum dry time between coats at 70degF.
Total cure/dry time (hrs)
Total inter-coat drying time for all coats.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Surface area (sq ft) = 500, Sealer type (1-7) = 3, Surface texture (1-3) = 2, Number of coats = 2 = 5 input(s) provided
  2. Calculate Total sealer
    Total sealer = gallonsPerCoat * numCoats * (1 + wastePct / 100)
    5.18 = 5.18
  3. Calculate Gallons per coat
    Gallons per coat = areaSqFt / max(1, effectiveCoverage)
    2.35 = 2.35
  4. Calculate Total material cost
    Total material cost = sealerCost + xyleneCost
    232.94 = $232.94
