How to Paint the Bottom of Your Fiberglass Boat - DIY

- In most boats, eventually you'll have to strip and replace the paint on the bottom of the boat. Today we're stripping the paint on the bottom of a boat and replacing it.
Step 1: Prep the surface, sometimes a light sand and clean is all you need
Step 2: Tent and tarp beneath the boat
Step 3: DIY sanding can take days OR you can hire a professional geoblaster
Step 4: Fill chips or cracks
Step 5: Wash the hull with fresh water (especially after blasting)
Step 6: Choose paint type
Step 7: Apply two-part epoxy
Step 8: Figure out how much paint you need (length in feet x width of your boat x .85, since the bow curves in and it's not a perfect rectangle = approx. square footage / 60
Step 9: For a crisp line, use painter's tape along the water line or the extent that you're painting
Step 10: Do the final coat in the morning in order to complete step 11+12 the same day.
Step 11: Do the thumb test to see if it's tacky enough for a thumb print. Making sure it's tacky will help the first coat of micron chemically bond together
Step 12: Apply first coat of micron
Step 13: Wait at least 16 hours (check can for instructions)
Step 14: Touch up any spots you missed if you were using a roller
Step 15: Apply second coat of micron the following day or months later
Step 16: Needs to dry for 16 more hours before splashing
Now you're done! The good news is you won't have to do this again - for years.

Can u paint bottom paint over antifouling?
This was a genuinely high quality video and demonstration. Thanks for getting me started on my project brother
where can I buy aqua bottom paint?? iv'e failed 3 times now
We supply a non-stick coating 10 year guarantee
Horrible tape job!
DIY 😂 cmon man
How did the micron csc work out? It's been 3 yrs Would like to hear about it
Butter my muffin !
Thankyou! So when your equations you said than you’ll know what your looking at. The final number lets say 2. What does that mean? 2 gallons? 2 quarts?
I'm really sure you can build it yourself. I did this 2 weeks ago thanks to the Woodglut plans.
Just an advert without telling anything about the paint, is it oil based? who would know..
Can you use that 2 part epoxy on steel or over other paints ?
What about under the jack stands? How do you tackle that?
Same question! HeLP
While it's on the crane. Leave it hanging until it's almost dry then you can splash it
How many 'years'?
You forgot to tell us how you paint underneath the braces that supported the boat ???😲
I personally would have the crane come back lift it up and reposition all the jackstands and supports ,then sit back down and then do the same process to those areas
Hi, on my small 12 feet boat i had some small cracks and holes on the bottom of the boat, i used gel-Kote and i cover the whole area, is it enough ?
Im going to be posting a video with in the next week of how i restored my 1957 12ft fiberglass boat and have been using it for 4 years! stay tuned and check it in. I think you will find it helpful. I watch all the youtubes i can before doing it and it came out great!!!
Did you have to strip the old stuff? Or you choose to? I am applying Micron CSC to my old bottom paint, so just curious.
Hi Michael, thanks for watching. Stripping off the old paint often depends on condition of the old paint and its compatibility with the new stuff. CSC is expensive, so you'll want it to adhere correctly. If I'm certain of brand/type compatibility, I have added new coats on top of old with just some light sanding. When in doubt though, I typically sand off all of the old paint. Just make sure you wear protective clothing, including the proper respirator. Many old bottom paints created toxic dust when sanded. The Interlux website has a fair bit of great info on compatibility and maintenance. www.interlux.com/en/us/boat-paint/antifouling/micron-csc Hope this helps!
Gonna love those square, unpainted sections under the supports. Nobody ever seems to cover that.
Literally why I searched how to paint the bottom of the boat. I'm working on a medium sized boat and I don't think I can flip it over safely
@@GoProXadventures Just move it once after you're finished! no other way to work arround them
Really? Here we go. Paint everything except where the supports are. Let dry. Jack up boat near one support. When the weight is off the support, move it. Paint newly exposed Hull section. Repeat.
@@keithjohnston5936 So one way or another we're going to be overlapping dry paint. I guess it wouldn't matter so much with a thick ablative or something, but it will never look smooth with a thinner paint unless the section can be wet-sanded and buffed.
scallen2112 I personally wouldn’t worry about what goes on below the waterline (looks-wise), I also don’t think it would have much of a hydrodynamic impact. Good luck with it.
I work for Epic Doors which manufactures high-performance fiberglass entry doors. We evaluated several paint suppliers including TruCoat 623, Sherwin Williams Polane 2K Acrylic, and Aquasurtech D200.
We were looking for an environmentally friendly, single component water based paint that was super durable, had great adhesion and laid down smooth.
Based upon our evaluation we selected TruCoat 623. It was much more environmentally friendly than Polane 2K and is a single component and TruCoat.Us had better adhesion than D200 and was priced better.
