What can you use to remove peeling paint on a inground pool?

A SANDBLASTER IS THE ONLY WAY.IF YOU HAVE EVER SEE ON OF THOSE BIG COMPRESSORS THAT IT TAKES A FULL SIZE PICKUP TO PULL YOUR IN THE RIGHT BALLPARK THERE.ANYTHING SMALLER WON'T DO THE JOB.

Sandblaster is not the only way. Can use a grinder with a disc attachment for grinding concrete.
