Estimate how many 5-gallon buckets of driveway sealer you need, with an optional material cost. The default 24 x 12-foot driveway at one coat and 350 square feet per bucket needs 1 bucket (0.82 used). Coverage figures come from HomeGuide’s published range of 250 to 500 square feet per 5-gallon container1; smooth or previously sealed surfaces cover more per bucket than rough or porous ones.
