I used to paint bottons for a marina as a kid. Very important. Use a pole on the roller. Helps keep the splatter off your skin. Take your time, go slow. Keep the roller from "carrying" too much paint. Always paint the roller tray before taking it away from the tray. Keep painting bottom of boat until practically no paint is left on the roller.
I don't have a boat, I just watched your video to learn something new. Thanks for sharing your knowledge.
I was sanding bottom paint on my project all morning! I swear to god what ever I’m working on at the time it seems like y’all just put a video out on it. I love it! Great show fellas
Perfect timing! I was just looking into repainting the bottom of my boat and, low and behold, this video pops up! Great information thanks!
I've been painting boats since 1970 and the #1 rule is use a brush not a roller! Rollers waste paint big time. It might take you a bit longer but you'd get at least 4 coats on a 21' boat. When using ablative paint plan on launching the boat within 8-24 hours. The longer it's allowed to air dry the harder the paint becomes reducing its sloughing abilities. Always hand sand with 80 grit paper prior to painting, do not use power sanders, you might leave gouges in the hull. No need for a different barrier coat, just two coats of paint. When hauling out power wash the hull while it's still wet! If allowed to dry any algae will harden like cement and aggressive sanding will be needed. In the Spring prior to launch day all you have to do is sand with 80 grit, rinse and apply one coat then launch.
It doesn’t matter if a brush gets you more coats if the roller gives you thicker coats
Thanks for the tips.
Glad ya simplified that for us . I went cross eyed looking at all the different kinds of bottom paint and was lost as to what to use . Ty for helping me out.
you explain this like a genius , every important details . Thanks a lot.
Your tutorial was clear and moved along nicely. Great for the easily distracted. Thank you
Perfect timing haha next month we should be preparing to paint the boat. Awsome tips as usual. P.s congrats for the new stuff that are coming for the fans.
Good tips. I have a few to offer from my experiences. Also have a bracketed boat, used to use Trilux on the bracket and tabs and copper based Micron on the glass, was never happy end of season with the Trilux, so went to Micron CF (copper free) for everything, and saved money for the quart of Trilux, one gallon covers my older 25 Grady entirely. Also because of the heavy buildup, I bought a floor tile scrapper from the Depot, which includes an integral long handle. I rounded off the blade corners, and in my driveway, I was able to scrap off the built up paint just about down to the hull or original first coat, I wet the hull and blacktop driveway to keep dust down but it’s mainly solid pieces I broom and shovel up unlike sanding. Must keep the blade sharp. I did 1/2 of the hull one year, the other half the next year. 1/2 takes about 4 times of about 2 or so hrs. Also, made the mistake of applying the paint straight when it was in the 70s and should have thinned it. A single coat too thick, where the roller would start sticking and you just go for more paint will always crack and flake off, better off thin coats say two. One too thick coat can’t be undone and creates the unevenness and peeling that sanding can’t get into the depths. I always thin the paint now, stay out of the sun, and paint in the 60s.
Holy Mackerel! I've been using bottom paint on my boats for 35+ years, sometimes incorrectly! I have learned more in the past seven minutes watching your video than I've learned in 35 years... thank you!
This is something I had no idea about. Very informative and helpful video.
The prize is you giving us awesome knowledge every Tuesdays that's priceless. 👍
Thank you for all your videos you have helped me out alot thank you and stay safe
I’m in the process now. I have a wooden Chris Craft which had the original factory paint from 65. Complete redo and a labor of love. That or I’m nuttier than squirrel poo.
Lol. Enjoy the season and be safe folks.
Here in Malta usually we leave the boat for summer season only. when I applied bottom paint I used to apply soft antifouling so when the boat is out from the water with the power washer it goes almost all from the hull and when you need to prepare it for the next season you just need to sand it lightly or nothing with the orbital sander .last season and this season I used antifouling from International but I noticed that when applying white colour it grows barnacles and algee much faster then dark colour as specially when you use the boat during summer season and you leave the boat after for a couple of months during winter. Another experience that I had I painted a boat for a season and the owner didn't put the boat in water and he decided to put the boat the next season and when summer was over he had the same result as usual , no algee a little barnacles.
Thanks for some great tips. I have the hard modified epoxy on the bottom. Too many coats. I try to power wash off as much as possible. Next time I paint the bottom, I switching over to ablative. Thanks again. Stay safe.
Another good one. Great information on bottom paint!
Gel coat on mine. She sits in saltwater for 4-5 months to a time. Take it out, bleach it while she’s on the trailer all clean again. Cayenne pepper trick is good to know!
Excellent advice and very informative!
Wow I work in a yard and painted many bottoms never knew that most antifoul needs to go in 3 days thanks for that bit of info
Thank you once again....I forgot to add, I have had bottom paint on my last four boats, since the late 1970's. My last three boats, for 36 years, I used Petit Trindad (highest copper content) and had great results. I now have a faster boat, and Cockrell Marine in Virginia used Blue Water AF45.. It all came off the aluminum trim tabs the first year, but the hull has done good. It is ablative, the boat is kept on a lift, and is used a couple time a week, year round.... I'm due for a new bottom paint job, and this video is SUPER helpful!
Yakim, how to you keep your boat winterized since you use it year-round?
Great tip on the different paint needed for aluminum. A lot of people probably use the same paint on the bracket & trim tabs as the hull.
The previous owner of my boat went as far as putting ablative over the anodes. Used car salesmen make terrible boat owner.
Great bottom paint information I didn’t know.
Man your videos have helped greatly over the years! Im looking at maybe changing my bottom paint brand but have always tried to keep using the same brand since I bought it. Any troubles with a sanding then applying a different brand than in previous years?
My boat was kept on a trailer so has ablative. I now keep it in the marina so guess I need to change that next paint job. I panicked about the painting of the aluminium issue you mention, but when I looked closely the fibre glass hull was green ablative but the stern drive and transom was painted same green colour but a non ablative. Hopefully there won’t be any corrosion issues.
So, I'm on year seven (in SW FL) with three layers of hard bottom (Pettit) paint after a sand down and a reseal with Interluxe 2000 and the antifouling over top since our last haul out. This is a 30 year old boat... We need to haul out sooner or later but have time. It is a 33ft. sailboat. I did a special black, blue, special black coating so I know when it's time pull out for another bottom job. Pro tip, do extra coats at the waterline... That said, we have a monthly diver that cleans the hull with a plastic scraper... metal will cut the time much shorter. Also, w/Marelon seacocks, so no dissimilar metal corrosion issues.
I'm bottom painted with Pettit Hydrocoat ablative paint. Until recently the boat was kept in the water full time. Now it's on a lift so I'll be touching up the paint more often.
Keep the great work!!!!
My boat has an Armstrong bracket. I use a copper free ablative paint. Using a copper free paint allows me to paint my trim tabs, bracket, and engine bracket along with the hull using all the same paint. I use an ablative since my boat lives in the water, but will get hauled occasionally for fuel and if a storm turns up the east winds for a couple days. Not great protection where I am from east winds.
I just did this last year with Micron Extra. She still looks good this year. So I’ll just touch up some spots and dunk her!
I have heard so many people say they put pepper in the paint. I have never tried. But it makes sense growth is living.
my boat that i have bought from up north has a hard paint that i want to get it off because it has a beaitiful gell coat underneeth and painted with a brush..looks bad and stops my boat going faster,i tried to take it off but it is reaaly thick and i can not do the bottom also do not want to damage the gell coat doing it,applied paint stripper for boats but like i said the paint is too thick,need to take it to a marina to get this paint taken off i live down florida in Boca Raton.
Born again? Love it. God bless you
Thank you! God bless you too!
awesome lift and paint cradle.
I just love your channel ❤!! Perfect for beginner boat owners such as myself! Here in NY we are not allowed to paint the bottom of the boat. Still very interesting information. Question, when checking the type does it have to be dry?
Thank you! Lol I'm not sure, I've never tried to check the type when the boat was in the water lol :)
Very helpful thanks for sharing
No bottom paint on the boat I have now. Kept it on a trailer, then when they closed the ramps for corona virus, I found a lift to keep it on. I’m looking for a larger used boat and bottom paint is a turn off for me. A newer boat with bottom paint would probably be fine, but new boats are out of my price range.
Nice to know info. Thanks for making this video.
Glad it was helpful!
My boat is in the water 4.5 months of the year, so yes here it is antifouling all the way.
AWESOME vid!
I do not have bottom paint on my power boat but may be putting it on this year.
I've been using VS721 bottom coat on my fiberglass boat the last 2 seasons. Does a good job but still needs to be pressure washed at the end of season. Sits in fresh water 4-5 months of year. No bottom paint.
In an older video you said that some commercial guys use latex house paint , I did that in October , boat hasn't been on the trailer since thanksgiving , so far it's held up great ,.. fresh water though
Sometimes I feel like you read my to do list.... great video!
Great info!!
I wish this video released when I was doing my first paint job. It would have saved me a lot of time and hassle choosing the right paint
Great video. I bought a nice boat with bottom paint in horrible condition. I trailer my boat, and have been working my tail off to remove the many layers to get to the gel coat. I’ve used an acid wash, then 3 sessions of paint stripper, and now I’m sanding my life away. Is there a high gloss bottom paint that can last years of being trailered and beached?
Bought my boat painted I’m about to try adding a new coat for the 1st time
For us up in NY that take the boat out for the winter, ablative paint you think is the best?
Sometimes if boat doesn’t have barnacles I don’t even paint it. Am I doing something wrong?
Also, when boat is taken out and paint is ok, if you use ablative paint, do you have to paint every season anyway?
I guess multi season Ablative is the answer?
AS ALWAYS, GREAT VIDEO.
I always really dig the videos man, very helpful. I'm a fiberglass technician in Austin Texas and I do bottom paint jobs all the time. I never heard of the cayenne pepper trick! How much is a good amount? I've only used Sea hawk brand bottom paint so far.
Thank you! That's awesome, I found the cayenne pepper trick from older boaters down here in the keys. Usually just buy a bottle and pour the whole thing in the gallon when stirring it lol
I just painted the bottom of my boat with Interlux Fiberglass Bottomkote. Not really sure why since this boat will spend way more time out of the water than in.
Good video. I'm keeping my next boat on a lift or trailer, therefore no bottom paint hassles.
For the contest prize this week I let you use my lift to make painting way easier 😂
Can you please make a video on how to paint tbe deck of the boat. And maybe the best paint to use to paint the deck
Thanks for the info. I won't need bottom paint but still good to know. What was the virtual catalog you were looking through in the begining of the video? Was it West Marine or another?
I’ve found that off the shelf anti foul is no good for a boat that lives in salt water. The best stuff is what they use on commercial ships. Navy ships use the good stuff and black in colour which lasts for up to two years without having to slip and paint every three months. I’m going by what is available in Australia and there laws on the toxicity. Off the shelf here is crap so putting chilli powder in may help. Good video thanks for posting always learn something. 👍🇦🇺
Horror story from my previous dealer who I bought a new boat from. He painted the water line too low and mid season took boat out of the water for work that was promised the growth was horrible. Asked him to raid the water line since I paid to have the bottom painted all he did was paint over the growth and strange reason felt it was necessary to scuff the gel coat above that. By the time the boat came out of the water the end of the season the hard barnacles that were on the bottom took a long time to get off. I had to redo it myself with primer and after the second season there was no growth. Worst dealer in history
My boat has bottom paint lives on a trailer my next project is to remove it and paint the hull.
If you keep it on a trailer you don’t need bottom paint. I think you have already come to that conclusion.
Perfect timing for me!
Yea , this kid is insane ! Best !!
;)
It's really a personal question to ask about my bottom paint.... In the deference to public transparency, I don't have bottom paint. The one time I did, I stuck to the bathroom toilet seat. It was extremely embarrassing explaining to the rescue fireman, responding to my 911 call, why I painted my bottom.. So there, you have the whole story.
Md Wills you animal
Perfect lol :)
Green Frog tape is much better than the blue tape for the record.
Just learned about the different paints the other day. Looking forward but not looking forward to putting a new coat on the bottom of my boat..lol
thank you
You mentioned to start decorating once you finish the first coat. Not arguing this but interlux and nearly all manufacturers have really long recoat times like 12-16 hours. Have you found this to be required ? Seems excessive. However interlux tech support said the times are necessary for the solevents to gas out between coats
Hey....I have ablative paint on my boat now, what's your advice if I want to repaint the bottom... what are the steps if I want to reapply ablative paint?
Hello, I’m needing to paint a doughboy pool top rails and want to know your recommendation please on what type paint to use. Our pool is inside and has started rusting so I was thinking that maybe a marine epoxy paint would work better and longer. The pool is chlorine indoor pool and
any suggestions?
Thanks,
Virginia
Can you spray bottom paint on with an airless paint machine or does it have to be rolled on? Before someone says "it's too thick", that's not what I'm asking😂 i want to know if there's a problem if the bottom paint is sprayed on, Thanks in advance👍👍
Just painted my boat with some rustoleum paint since it spends it life on a trailer. Interested to see how it holds up for the year
How’d it hold?
Good video
The knuckle head that owned my boat before me put ablative on the lower units, bracket, and trim tabs. He also painted over the anodes. 🙄
In November of 2019 I bought a 22 year old, 23' Wellcraft that had never been bottom painted. I am keeping with that tradition. I think boats look much better with out bottom paint.
how is that working out for you? did you paint it yet
New boater, bought a new StarCraft deck boat and had it bottom painted. I moored it and only pulled it out 2 times this summer. The second time it was covered with barnacles. I was told the anti fouling paint that they applied would prevent barnacles. Any insights into why this did not work?
What's the proper process to bottom paint a trim tab?
Does mercury require a space between the bottom paint and engine mount where you don’t paint the bottom? Or can you paint the bottom right to the engine mount ?
I was thinking about sanding the bottom down next season on my boat. Probably wouldn’t sand blast it because it you be too expensive would probably just use an orbital sander. There is this paint a couple of my buddies have been using what I think is called aqua guard that I might try. I usually don’t paint the whole bottom I usually just touch up, even though we are in a wet slip. And my one question. When you sand the bottom down do you need a primer coat before you put the paint on?
Usually, yes, you'll put on a barrier coat, but it depends on how deep you sand. If the gel coat is in good condition, you can get away without the barrier coat sometimes. It all depends on how much you want to do and what the budget is ;)
I bought a boat that already had bottom paint It and it is faded so I want to put a coat on just to freshen the look up do I have to use marine bottom paint or can I use another type of painting being I only trailer it.
I just bought my first boat last year and ran it last summer.. Now I am ready to get back in the water.. I have a marina slip so the boat will stay in the water until October. My bottom paint is black over blue and the black wore off over last season exposing the blue in much of the painted area. What do I do next
My boat doesn’t, it’s a 72 out drive and the motor mounts dropped which we are rebuilding.
Okay this might be dumb but I don’t need bottom paint at all but no paints that aren’t copper or ablative or whatever say they’re only for the top side. What type of regular paint can I use to paint the bottom side of my little center console ? I don’t really feel like gel coating it because of how much work it is. Can you just use weatherproof rustoleum ? I went to a place and they sold me this oil base gloss paint that looks like crap and dries clear and almost feels like resin when it’s dry. Im not very good with paint so I could really use the advice, thanks.
My bottom paint is falling off. It's now a fresh water boat but the bottom of my hull looks terrible, so I want to paint it with a hard coat to look nice. What is a typical cost of having a yard do the bottom on a 17ft boat?
At 02:30 you state a boat kept out on a lift doesn't need bottom paint. From reading other comments, etc. do I understand correctly that I also DO NOT need bottom paint on a boat that is always on a trailer (and at most might spend a long weekend on a dock once in a great while)?
Thanks, for another informative video. 👍
That is correct :)
I use Pettit Hydrocoat
I trailer my boat and only use it in fresh water. Can I just spray an automotive base coat with about 5 coats of clear?
I still use bttm paint on my center console
Do you have to sand or scuff the bottom if you already have bottom paint on
My boat is on the east coast of Canada so I have some MicronCSC on that bad boy
Micron CSC is the best hybrid paint out there, I work in a boat yard, and if we could get the price down enough I would love to make that our "house paint" for doing bottom jobs.
Yes I just purchased a boat and I was looking at total boat bottom boat paint to use the boats 33 ft long she's got Barnacles on her belly and I'm going to power wash those little puppies over there but I just wanted to ask a question I was looking at your video and I'm pretty much just going to like leave my boat in the water I'm going to slip it so by your video you're saying I should use the hard paint because I'm going to leave the boat in the water I just my reason for asking cuz it's a pretty sizable both and I ain't going to be yanking that thing out the water every 5 minutes
what do you think about cooper coat?
So what kinda paint is it if it's flaking off? Recently bought a Hunter 23' with the bottom paint flaking off all over the place...
Someone before me painted the bottom and all the out drive with bottom paint, now I have to find a way to get the bottom paint off the out drive without taking off the original paint. Any tips for removing it?
Thanks Great video!
You can try pressure washing it, but that might not work and sanding it and repainting it might be what you have to do
My aluminium boat sits on a trailer, so it's not painted. But this was interesting regardless!
Hey bud how are you doing. Do you have a video doing a sea trial on the ocean master. How fast it goes, I have the same boat with a 250 hp and I wonder if a 300 hp is worth.
Thanks and I enjoy your videos and channel.

Great videos what does the pepper do to help the bottom job?
Just helps prevent growth, it's strange, but it does work lol
Can I use any of this paint for the bottom of a jetski?
I had to strip/sand all gel coat from the bottom of my old seacraft. Boat will sit mostly on a trailer do you think petit vivid is a good choice ?
Yes, that's great paint for brighter colors :) The brighter colors get growth faster than the dark colors though, just something to think about. The vivid is a great paint though :)
Born Again Boating
I was thinking a dark blue and white topsides
No bottom paint on my boat. I have a 1760 Jon boat in northern Illinois.
What is the easiest way to remove (very thin/worn away) bottom paint? My hull on my boat is a beautiful sky blue and the previous owner painted the boat and it was kept in the water. I trailer it now and would like to remove it all to have that beautiful blue color on the bottom of the boat again. The ablative paint is almost all worn down and you can see the hull in some spots. Any advice? Thank you!!
You can try to carefully pressure wash it off. Sometimes with it being ablative you can pressure wash the paint of, but be careful not to use to powerful of a pressure washer and get into the gelcoat. Outside of that, it's sandblasting or sanding, and thats a nasty job :(
Born Again Boating thank you for the help. I tried with the pressure washer and that did nothing. You answered my question that I already knew the answer to. Sanding! I was hoping there was an easier miracle stripper or something. Looks like it’s going ti stay the way it is. Way to much work.. thank you sir
If you left two boats in water, one with ablative and one with hard paint, what would have less barnicles?
I feel like there are too many variables to be factored in here, this is a question for a bottom paint manufacturer or the bottom paint store :)
You forgot some important steps my friend! Most notably, you have to put on a respirator and coveralls because bottom paint is extremely toxic. Also it doesn’t hurt to do 2-3 coats of the salesman stripe :)
I work in a yard and we have to be in full suit , respirator full face gloves the older guys are like you have to wear all thsts stuff to roll lol
