Need help glassing a Bayliner floor - question

[carolinadarin]

Hello,

I am a fiberglassing newbie forst off. So I ripped up the carpet on my 1992 19' Bayliner Classic and found some rot beginning on the deck. One side of the foam was waterlogged and I ripped it out. The other side was completely dry. I cut out the rotted areas and and replaced them with plywood. Sealing the seams initially with foam so the resin wouldn't leak through.

Now I glassed over the wood, but only used the fiberglass cloth on the seams. Should I have used fiberglass mat over the entire floor to be safe? Should I now sand the entire floor and put another layer of glass and mat on it? Or will it hold up the way it is? (fyi - I am putting down Nautolex Marine vinyl flooring so water wont run right through it like carpet I dont think)

I have attached some photos for you guys to look at. And I appreciate your advice in advance!

Did you check the stringers for rot?
You need cloth, and the bottom is not sealed; more rot coming.
Read old posts.

That all depends on what your choice of resin you picked. If an epoxy based product then you won't need to do anything else. If a polyester product then you will need to sand and reapply more resin with mat. Poly will crack like peanut brittle if used alone.

It looks like the resin is styrene monomer.. That would be polyester right? If so it looks like I am in for some sanding.

Oh and do you prefer using a roller, paddle or brush on a job the size of an entire floor?

For sealing I used a plastic spreader on the 1st coat. The wood will soak it right in. For the second coat I used a 4" foam roller. I poured it right from the pot then just spread it out with the roller.

I think I used about a gallon of epoxy just in sealing.

BTW, like Coors said. Go ahead and check stringers and transom for rot while you've got the deck tore out. Your deck doesn't look too bad to me but you can never tell about the stringers until you check them.

Thanks for the advice.. Dumping it out and rolling it sounds much easier than brushing it that's for sure. Do you think I should use epoxy or stick with polyester resin since that is what the first layer is?

just stick with what you're using, unless you removed everything you aready put down using epoxy for the rest won't make any difference.

you also might want to add another layer of matt then cloth over the seam area.....you just used cloth.....the matt will be far better on the inital surface contact......just go a little higher up the sides with the matt.

and as allready stated......the poly will be just fine

I don't think he sealed the underside..

Re: Need help glassing a Bayliner floor - question

I actually used pressure treated wood.. does that help with it not being sealed underneath? I can still reach about half of it to seal it with a brush in the open areas. The area where the gas tank is is completely encapsulated.. will it still rot?

Did you check the stringers for rot?
Pt ply, will try to warp, did you fasten it good? and seal the screw thru the stringers?
Did you use the correct fasteners, as the new pt chems eat up the normal ones?
Before you go further, think you need to search old threads in here.

congrats on the big 3000 coors !

keep it comin.!


as far as the repair.....coors has suggested the correct way for a long term repair.....(20 + years)

what you have done, is a minimum 5 years if you treat the boat somewhat good.....(allways covered when stored....bow up....ect)

the difference between a 20 + year repair and a five year repair, is very minor as far as repair time and materials.

but if done correctly.....the repair will out last the rest of the boat

Re: Need help glassing a Bayliner floor - question

Thanks for your help fellas.. The stringers are still like new and the glass over them is nice and amber.. I used stainless screws like everyone here said.. I used more than enough of them to fasten the board down.. I thought the glass over the screws would be enough to seal it.. At this point should I rip it back up, use non treated ply and seal with epoxy on underside? I bet it is hard to get feshly glassed plywood up that has an excessive amount of screws....And how do I seal the screws like you say.. This will be my last question.. thanks again

Thanx! Oops is right, I hate repairing so much that I go overboard with any wood repairs-never want to deal with that same piece of wood again.

it is allways better to glass the underside of the wood as well...any wood...(pressure treated needs to be bone dry)

but you used pressure treated wood, pressure treated wood by itself, can sit in water for 10 years without rotting......

i would suggest that you go out, enjoy your boat, dont give it a second thought.

if....for some reason, in 10 years the deck feels soft, then you can redo it by glassing the underside......

cheers
