How to Remove Foundation Waterproofing

Dianna Morrow has a common problem.

She's building a new home in Hardy, VA.

Here's what she sent:

"The waterproofing spray on my foundation was applied with lots of overspray above grade.

The builder has tried grinding it off, painting over it and some other coating that cracked terribly.

What options to cover/correct this do you suggest?"

What a mess! Someone didn't follow the chalk lines or they were snapped in the wrong places. Photo credit: Dianna Morrow

Here's my answer:

Dianna, it's time to rent an old-fashioned sand blaster.

That will remove the mess.
