9 Easy Steps – How to Strip Paint from Aluminum Boat

Nobody wants to keep a boat that’s got a bunch of chipped paint, scratches, and just plain unattractive.

With your boat’s surface constantly wet, it is inevitable for the pain to chip. Before you paint it all up, you need to perform these steps to give you the best quality you want.

1. Know the different techniques

There are different methods when it comes to stripping paint from your boat.

It includes the following:

  • Shot-blasting – it involves the use of a special machine that helps to remove any impurities on your boat’s surface
  • Chemical stripper – these are materials that remove the paint the quick and easy way
  • Mechanical scrapers – you will need sharp tools that can loosen the paint (it’s a lot of work, too)
  • Sanders – this allows you to remove paint in 2 ways either with a sandpaper or a sanding attachment from a tool.

2. Decide on the method to use

I suggest that you go with a technique that is simple, yet effective. If you are new to this whole task, the easiest method I recommend is the use of a chemical stripper. It is effective and does not require much mechanical effort from you.

3. Find the right place to work.

Stripping paint off your boat is a messy job. You don’t want to create clutter in your home or have a bunch of small objects wafting around. You and your household members may end up breathing these things or stepping on sharp items on the floor. So, the best place to work on your boat is outside where there is not a lot of foot traffic going on.

4. Gather your tools.

Now that you know what method to apply, let’s go ahead and start by preparing the tools. You need a chemical stripper, and I highly suggest that you get a superior-quality one. There are cheaper ones out there but the result is subpar. So, it helps to invest in a brand recommended by experts to give you the outcome you expect.

5. Get your scraper ready.

Older boats with chipped paint have bumps and flakes. If you prefer not to use a chemical stripper due to budget constraints, opt for a paint scraper instead. This should suffice when it comes to removing nasty flaky paint and get the surface smooth.

6. Stay safe.

Removing paint from an old boat is a serious matter.

As I mentioned earlier, it can involve some safety concerns with old paint and some material flying off your boat. This is why you need to protect your eyes as you work on this task. There are also some materials that can impact your lungs, so it is best to stay safe. Wear goggles and a face mask to keep your eyes and nose protected from these foreign materials.

7. Remove the flakes.

Now that you have your safety equipment ready, it’s time to get started. Use your scraper to remove the flakes. Be sure it is sharp and blunt to really cut through the flakes and old paint that you want to get rid of.

8. Use your chemical stripper.

If you want to finish off the job with a chemical stripper, then go ahead and get it going. Mix the contents in the can well by giving it a good shake. Then, apply a single coat of this material on the boat’s surface. Leave it on for a few minutes and it should do the work well.

9. Do some finishing touches

With most of the flakes and old paint gone, a few finishing touches should be all that is needed. Grab your grit flip discs and get rid of the scrape marks with it. You can also use an acid wash to brighten up the hull and the overall tone of your boat.
