The Driveway Coating Calculator computes the number of pails (4.75 gal) needed to coat or seal a driveway.
INSTRUCTIONS: Choose units and enter the following:
- (L) Length of Driveway
- (W) Width of Driveway
Pails of Driveway Coating (P): The calculator returns the number of pails of driveway coating if applied thin or thick and the area of the driveway in square feet.
The Math / Science
A driveway has a measurable surface area. Even if it is a winding driveway, one can measure the length and multiply that length by the width to get an estimate of the surface area of the driveway. Pails of sealer (as pictured) specify the number of square feet they will cover. The product shown lists a range of 250 ft2 to 350 ft2 for one pail depending on how thick it's applied. The Driveway Coating Calculator computes the surface area of the driveway based on the length and the width and divides the surface area by the high an low range to give the user an idea of how many pails of sealer that will be needed for the job.
