Q: What is the estimated cost per square yard of sandblashng a continuous exterior concrete wall when the total area is about 5,000 square yards?

A: The estimated ranges of costs per square yard for sandblasting are:

Brush blast (1/32 inch deep)

$1.35-$2.70

Light blast (1/16 inch deep)

$2.25-$4.50

Medium blast (1/4 inch deep)

$4.50-$7.20

Heavy blast (3/8 inch deep or more)

$6.75-$15.75

If all other factors are favorable, presumably the cost range would be toward the lower end of the scale on a 5,000 square-yard job.
