I need to brace a dock. The place where I was going attach the brace is underwater. Using nails and a hammer would work, but I was wondering if air powered tools will work underwater. It would make it easier and quicker.

Air will compress. Water will not. Be careful with your idea.

Do NOT use WD-40 on air tools. WD 40 will ruin the rubber o-rings in the tool and you will get air leaks.

I would expect it to get hydraulic lock after the first shot. the air will blow the piston down but on retract it would suck full of water.

While not good for it a cordless drill would probably have a better chance of functioning.

The cylinder the hammer is in will fill with water, you might get one shot then you will be blowing seals or worse.

Try it and post your results. :popcorn:We're all curious.
To quote my favourite saying from one of my favourite shows: "I don't think so Tim."

This is why I ask before doing. I want to find out if someone has tried.

A friend of mine used an air impact driver/drill on lag bolts underwater to brace a dock. Air nail gun is open for exhaust on top so may suck water on recoil. I’m not trying my $299 framing gun underwater.

But really, how hard would it be to pre-drill and ratchet down a bolt? Bolt would be better than a nail anyways.
...Now, if you could figure out a way to snorkel the recoil of the nailer, then you might have an interesting solution.

I see a "As Seen On TV" gadget in the making. ;)

I used an inexpensive palm nailer from harbor freight today and it worked GREAT!
Was shocked that it worked and didn’t lock up like some replies in this thread indicated it might. I was 7 feet down driving 16 penny galvanized nails through a 2x6 into an old dock pile. Worked great. Good luck.
