How To Bottom Paint A Boat On A Trailer
But why is bottom painting important? Well, it protects the boat and prevents the growth of algae, barnacles, and other marine organisms. It also ensures that there’s no slime and your boat uses less fuel to function optimally.
Now, let’s quickly get to the point and walk you through the steps for painting the bottom of your trailer.
How To Bottom Paint A Boat On A Trailer
Make sure you follow each step carefully so that you face no problems at any point.
Clean The Boat
Start by giving your boat a thorough cleaning. This will remove slime, algae, etc. before it dries up. Dried slime is always harder to remove. If there are stubborn stains, you can use a scraper to loosen it.
While cleaning the boat, you may also want to get rid of all the old paint. Strip it of the old flaking and chipping paint so that you have a neat surface to work on. You can use a hook scraper or a chemical scraper based on how stubborn the problem is.
Start Sanding
- The second step to bottom painting a boat on a trailer is to sand the surface. This is especially important if the existing paint is in good condition. 80-grit sanding should help smoothen the surface.
- Make sure you only use an orbit sander and not a belt sander.
- Once you are done, you should clean the boat again to remove all debris that may have collected during the sanding process.
Protect The Trailer
Using a high-strength masking tape that can last for days, mask all the borders of your trailer. Do not use ordinary tape because it can’t stay more than a day. After this, you should bring out newspapers, sheets, etc. to cover the trailer completely. No part should be exposed besides the one that you want to paint.
Prepare
Bring out the bottom paint and read the instructions carefully. You may need to shake the paint, add a thinner, etc. based on the type of paint you have. To shake it properly, you can use a shaker or fashion one with a power drill and the mixing paddle. This process should take you around 15 minutes.
Start Painting
Now, you can go ahead and paint the trailer using a roller. 2 coatings are the norm but this also varies from paint to paint. The instructions will have this information. Mix frequently and apply patiently with no rush.
Remember to wait long enough between coatings and at the last stage when the paint has to dry.
Conclusion
You can follow the same steps for all parts of the boat by repositioning it and then painting it. This will ensure that you leave no part behind. If you have any questions about the process. Feel free to ask us.
