I will try to keep it short. I had major back surgery and Dr told me to get a hobby like fishing to be semi active. I found a good deal on a 1986 20ft center console saltwater boat and got it to use in the local lake and when on vacation I could use it in the ocean. I have always wanted to saltwater fish. First and last time I was 12 and with my dad and immediately got sick lol. I am 47 so I wanted to try it again. The boat had 2 soft spots in the typical areas. In front of console and in front of the motor. Come to find out the whole floor was soaked. I got Git Rot and drilled holes through out the floor and injected the resin and it did no good at all. I was told to get sheets of plywood and paint it with Durabak 18 textured coating. So I took the console out and spent probably 100+ hours sanding inside and outside of the boat. Put the plywood in which took awhile cause I wanted it to fit perfectly. Then chalked seams and the sides so water couldn't get between the new plywood and original flooring. Then I put the textured Durabak 18 down after a few coats it started looking good. That stuff is hard to work with and gets thick within 2 hours or so. Not easy to do as I thought it would be. I painted the outside sky blue and inside light cream. I spent over $1000 for just the Durabak. One gallon and a quart of blue for outside and 5 gallons for the inside. It looks good 10 feet away lol. The outside I got the smooth version and did the bay doors. The next I went out to check it and the wife and I were excited. Dang it's gonna look awesome! Open the can to paint the outside and the paint is hard. Cured. I called Durabak and after they talked with management they sent me a gallon for free. Shocked but happy. I coated the outside and walked away for few days. When I went back to it, I got sick to my stomach cause of all the air bubbles. It looked like a semi gloss textured. It looks like a commercial fishing boat. Embarrassing but I go to the lake almost everyday for about 2 months now and I want to go to Gulf Shores Alabama and saltwater fish. I have been down in my back for about 2 weeks now and barely able to work so no fishing. I felt ok yesterday evening so I planned to go fishing this morning so I got the water hose out last night to spray the ants off the boat and the Durabak is coming off inside in a few spots. Outside is sticking good just ugly. I know I got to redo it all over again and get all the Durabak off. This is really depressing but I can't just let it go. Reason being, my mom passed and I used what she left me to buy the boat and fix it up. Get this, boat registration numbers are her birthday numbers. How cool is that? Sorry this is so long but I need advice on how to fix it. Is the flooring ok the way I was told to do it? Its actually holding up good. Paint wise inside and out i am at a lost especially with money being a issue. I am new at this so please be nice lol. Thanks in advance.

Gtallent first thing welcome aboard !
Ok, whoever told you to lay another layer of ply over the existing deck did you a big disservice .. If it's rotten it's gotta come out and chances are the stringers and transom has rot also . Sorry about the duraback problems . I've never used it I'm not much help . At this point you should ,if you plan to keep the boat,take the extra weight of the added plywood out and tear into the deck in the bad areas . That way you can inspect the foam and stringer system .
Chances are it will be a total gut job rehab . I know this is not what you are wanting to hear but 99% of the time this is the case ..maybe you will get lucky and the structure is fine . No way to tell unless ya dig into it .
An inexpensive alternative to your duraback is just good ol rusto enamel paint with the added enamel hardener ...
Good luck lots of great folks here to help guide you through if you choose to repair the boat ..

Welcome aboard.

As sphelps pointed out, you have a "deck over" which is just covering up the ugly rotten floor and stringers below. In my opinion, not a safe move.

Regarding durabak, its nowhere the product it is claimed to be

Yea I know this sounds repetitive....but I've heard nothing good about using it for a marine application.

Thanks for welcome guys. I don't know much about boats so when I start on it again I will definitely ask yall before doing anything. Especially when it comes to the stringers.

I used Durabak when I restored my boat. The stuff is junk. It doesn't adhere very well and it is not durable.

No, and I don't don't really know how to get rid of the Durabak. I covered the entire floor and the insides of the hull to the gunwales. (You can see details in my restoration thread - link is in my signature - starting about post #172.) There are a number of places where Durabak has peeled and/or worn through. In many places, though, it is still adhered pretty well. Getting it out would not be easier. For now, I'm just living with it.

It's pretty frustrating to spend so much time fixing up a boat only to have a product like Durabak fail so miserably. I really wish I would have gone with gel coat.
