The average cost to sealcoat an asphalt parking lot with either asphalt or coal tar emulsion pavement sealer ranges from $0.14 - $0.25 per square foot.he average cost to sealcoat an asphalt parking lot with either asphalt or coal tar emulsion pavement sealer ranges from $0.14 - $0.25 per square foot.
In the example shown, the cost of a 2.5-mil thick coating using a powder costing $2.50 per pound and having specific gravity of 1.4 is 4.6 cents per square foot. This assumes 100 percent efficiency.If overspray recovery is 98 percent, the cost would be about 4.69 cents per square foot.eferring to the table, actual coverage of the powder is 128.8 square feet per pound and the cost per square foot of a 1-mil thick dry film is 2.29 cents. Thus, the actual cost of material for the epoxy powder coating is less than that of the liquid paint coating by 1.23 cents per square foot.
