    Air tools underwater

    Has anyone ever used regular air tools underwater? I run a small commercial pool service company. I do alot of rust stain removing in the bottom and sides of pools. The cause of most stains are wire ties or rebar to close to the gunite or into the plaster. I have been removing the plaster with hammer and chisel. Removing the wire or rebar with file and or saw. My budget will not let me purchase a real underwater tool. Just wandered how well air tools would perform under water. The life of the tool.

    I use pneumatic chisels underwater with excellent results. I splice an air line from a regulator hose with hose clamps and a piece of Stainless tubing. Of course it can also be run from a normal air compressor.

    I have purchased very inexpensive pneumatic tools from Harbor Freight ($9-$15) I think and they last a while, even for marine use. You do need to soak them in freshwater after use and also add a lot of oil during extended use and also before storage. They seem to "dry out" quicker when used UW

    I've used quite a few different air tools underwater, but the critters like to eat up the air so use a compressor rather than a tank if at all possible.
    You'll also want to use vegetable oil or mineral oil in the critters; petroleum products are an environmental no-no.
