SUBJECT: # 26660: How Do I Remove Bottom Paint?
Submitted by Salty Dave (66.21.107.78) from FLORIDA on 6/8/04 8:20:00 AM
would like to know your best recommendations for removing bottom paint from my Grady? Not sure what type of paint it is; however, it's light "Aqua" in color and was really thinning and "running" when I used a hull cleaner on the boat. I think the hull cleaner is an acid based cleaner; however, it wouldn't fully take the paint off, only made it run a bit. Thank you for the help.

...how much paint you have on there. If you have only a couple/few coats, interlux stripper on a warm/sunny day will take it off. Put a painters tarp down and apply it and go over it again as it starts to gel and will hold more and then push it all off with a scraper when you can see it lifting under the gel. With a helper, it will be done in a couple hours.If you have many, many years of paint on there and it is so thick that you have 'mooncraters' from chipping...you will have to hydrosandblast it off. I have never done it (but wish I had on 1 boat), others can help you better if this is your scenario.
But...if you do not have much paint on there and it is all uniform looking with no mooncraters (mooncraters will slow you down and use a lot more gas to push the boat), then I would just leave it. Some hull cleaners, like On & Off will do what you decribed to some paints, not a big deal but do be careful with that stuff, the phosphoric acid is very dangerous. If your paint scrubs off easily, likely it is ablative paint, which is supposed to wear off as it is chemically spent.

A couple of weeks ago I was way out in the country going to a friends house when I passed a place that was being repainted. The house was old and the paint on it was somewhat, though not badly, flaky. I've seen bottom paint of about the same quality. Anyway the young guys who were getting the thing ready for new paint were removing all of the old loose stuff. They were doing it with a weed eater. It was working and working very well. I stopped and watched for a few minutes, talked to the young fellow just briefly while I was there. He stripped a wall that was probably 22 feet long and whatever single story is high in about 10 minutes. It was obvious that any paint that was even remotely loose was being removed and all that was left was stuff that was a good tight bond to the wall. I am sure that if I were getting ready to repaint a bottom, particularly one that had many coats of nasty old bottom paint on it I'd try this as my very first shot at cleaning it up. I haven't done it, but I'd sure try it. It sure was working on that old farm house.Thom

it didn't work. The spousal unit looked at me kinda funny standing out in the driveway weedwacking the bottom of the boat. She was mumbling something about when I finished with the boat to start on the frontyard. I put it back in the shed REAL quietly :)
