Prep Your Boat
This is undoubtedly the most vital part of the cleaning of your boat. Because of this, you need to take your time, and here are some of the activities that will be involved when doing all this.
Clean Your Boat
The first thing to do is thoroughly cleaning your boat. It’s best to do this immediately once you’ve taken your boat out of water because, at this point, it’s a lot easier to clean. And when doing the cleaning, make sure to use a high-pressure hose or wash together with rags and a scraper.

Remove All the Hardware
You must take out as much as possible to achieve a clean and smooth paint job. And although this might be time-consuming, it’s the only way to guarantee that your paint job efforts don’t go to waste. This step entails removing all the aluminum siding on your boat, but if there are hardware pieces that completely don’t come off, place a painter’s tape over them.
It’s essential to make sure that all the hardware has been removed because the paint will be on the boat’s hardware piece. As a result, this paint is more likely to allow debris and water to penetrate, which makes it start cracking over time.
Due to this peeling off paint and flaking, another paint job will be necessary, which is expensive and time-consuming. Therefore, you should avoid such possible issues in the future by thoroughly removing all the hardware from your boat’s surface.
Remove the Wax Coating
Paint or primer doesn’t stick to the wax. And because almost every boat comes applied with a wax finish, it’s essential to make sure it’s removed before applying the paint to avoid possible issues. If unsure whether your boat has a wax finishing, run your finger along the boat’s surface for a definitive answer.
When removing the wax coating, you need to use boat solvents. And as you do this, make sure to apply some pressure when using the coarse sponges to ensure all the boat’s wax has been removed. This might take your time, but you should only proceed once you feel no boat wax is left on the boat.
Mark the Area You Intend to Paint
It’s critical to identify the area that needs painting. This means inspecting dings, dents, and any other area where the paint is peeling or flaking. Once you’ve identified these spots, go ahead and mark each of them using a tiny piece of tape to make it easier for you to pick out the areas which you should address.
Scrape off the Peeling Paint
Once water and air find their way between the boat’s surface and paint, it causes the paint to start peeling. And this will continue happening even after you’ve applied a fresh coat of paint or primer. If you don’t want to waste your time and efforts, start by scraping off the boat’s paint. By removing all the peeling paint, you’ll be able to make sure it’s spread uniformly and well-adhered.
When the paint you’re applying differs from that of your boat, you need to scrub and sand off the entire pre-existing paint. You should do this using a sharp-putty knife and, while doing this, confirm the knife’s edge is parallel to your boat’s surface. By doing this, you avoid cutting the boat’s surface and making new dents, which is more work.
Sand Your Boat
Get 80-grit sandpaper and start sanding the whole boat surface. Doing this is essential since it improves the paint’s grip on the surface and facilitates the uniform coat of paint. When sanding your boat, there are crucial things you need to observe, including;
- Never use a belt sander on the boat.

- Wearing eye protection and a respirator while sanding due to safeguard yourself from the toxic paint chops.

- Go through the manufacturer’s paint guidelines: There are different kinds of topside boat paints.

- Apply the first paint coat: Feel free to start applying the fresh paint after mixing the paints as advised by the manufacturer’s manual. You can choose to either apply the paint by brushing or rolling the topside coat, but first read the manufacturer’s manual to see if they recommend it.

And while rolling or brushing the paint, make sure to do this parallel to the finish’s waterline. Once you’re done, give the paint time to dry and then go ahead to other needed coats as advised in the manufacturer manual.
Remove the Tape
You should start taking out the tapes before drying the last coat of paint. Doing this is essential because leaving the final coat of paint to dry increases the chances of the paint to peel together with tape. Due to this, you’ll need to start the prepping and painting of your boat again.
