Sandblasting an aluminum boat

- As I planned to restore a 16’ aluminum Lund fishing boat, I was not sure if my plan to sandblast it would be a safe way to remove paint and surface damage. A quick video search did not yield any definitive answers, so I decided to try it and make my own video to provide some insight.
My compressed air system, sandblaster, and air dryer components are pretty standard items. However, until I added the air dryer, the sandblaster would continuously plug up with wet sand. Now it works flawlessly!
Using #4 sand, the dings and scratches in the aluminum disappear and the blasting leaves a slightly raised, spalling effect. This allows a quick sanding with 220 grit sandpaper to level out the surface into a polished look. Some buffing with a cutting compound or metal polish brings the bare aluminum parts, such as the gunnels, back to a lustre finish.
Awesome video. Im getting ready to restore my 16 footer as well. Been painted a few times. Was trying to decide what route to go for removal!
Finally!!! I’ve been waiting for somebody to post a vid like this. Great job
I appreciate that. I could not find a video that really demonstrated what would happen. Glad it was useful!
Hey outstanding video. Where did you get the air dryer and what's the part number?
Thanks, brother! It is from a Canadian retail chain called Princess Auto. Here is a link to their listing. You need to buy the desiccant pellets separately: www.princessauto.com/en/in-line-desiccant-air-dryer/product/PA0008055757
Finished boat? Any vid?
It does contaminate the aluminum if u need to weld on it.
It sure would. Do you think a wipe down with acetone would clean the aluminum enough to weld?
@@28fish no. From what I'm told the media gets embedded into the aluminum. I have an aluminum boat that was blasted with the wrong medium and when you weld it just melts like solder.
I was told by a pro, to use crushed glass, not sand, on aluminum.
Your sand media looks like it's leaving lots of roughness on the alum
I actually tried glass too. It resulted in larger pock marks and a very rough finish. With professional equipment and a finer grit of glass than I can get I’ll bet that would be the way to go.
What sand were you using?
A #4 blasting sand we bought from Peavey Mart. They sell it for $11.99 per 25 Kg bag.
