Deck repair

[pozenbaugh]

I am putting a new deck in my 1976 Viking SportDeck Boat. What type of wood would you use; plywood, treated plywood, or marine grade plywood? And then I was thinking that when I get the floor back in I would use herculiner or something like that to cover it and water proof it. What do you guys think? Thanks for you help.

Re: Floor repair

1st it is a DECK, not floor. exterior plywood, sealed on all edges, and screw sealed after install, then glassed in. any hole after this, gets sealed with 3m 4200, there are alot of finish applications that can be used, as herculiner, hydroturf,(used on jetski's)

I have an OMC for the stern drive and a 5.0 engine also.

Have you had any problems with your floor?

How hard is it to glass the deck? What kind of seal for the edges? And as far as exterior plywood is that the green treated stuff? Sorry for all the questions.

Re: Floor repair

My deck,stringers, and transom are in need of replacing. But we cant really expect anything but rot considering the 30 plus years the boats have on them. Do you have any pictures of your boat?

The only one I have I just put on the avatar. I will take more when I get the finished.

The green is exterior, yes, but pressure treated. You'd have to let that completely dry out otherwise you seal in the moisture. Slowly else you'll warp it. If you read around this forum, you'll see some using that, and others using what Tashasdaddy has mentioned, exterior AC plywood.

You'll want to seal the wood with the same resin you use with your fiberglass layup. You'll probably want to choose either polyester or epoxy resin. Both come in types especially made for fiberglass layup. This is often referred to as laminating.

For plywood, you have a lot of choices. You will want to choose an exterior plywood because the glue is waterproof. You can choose between marine plywood, pressure treated, and BC. There are a few other varieties but that's what most us use.

Spend some time searching this forum for polyester, epoxy, and plywood and you will find much info and debate on which to use. There's tons of info here and you will ultimately have to decide for yourself which materials to use. If money were no object, I think most of us would use marine plywood and epoxy. They are the best materials but also the most expensive. That doesn't mean you have to get the most expensive stuff to do quality work.

Re: Floor repair

Thanks for the info guys, and yes money is an issue.

How do you dry the plywood??

Re: Floor repair

Re: Floor repair

I dry it flat on the floor. That way you can keep weight on it to hold it flat as it dries. Lay strips of wood down on floor, then plywood, more strips, more plywood, etc...then something heavy to hold it down.

The sun helps, as would a fan.

Re: DECK repair

Do I need to replace the foam in a boat like this or can I just take it out and leave it out?

If I leave it out will it effect how the boat floats or does it just keep it from sinking if I take on a lot of water?

law says under 20 feet ya gotta have it.......that only will come up in insurance issues.

some replace...some dont.....

it can be structural to some boats. adding as much as 8 or 10 percent of hull integeity......


so ....its your call......

as far as the plywood question.....

read tashasdaddys and i386 posts a few times....i386 gave you a really good post

cheers
oops

Re: Deck repair

Thanks oops. As far as the plywood I bought CDX and dried it as the above post stated. As far as the foam, in your opinion would you replace it?

 

[oops!]

Re: Deck repair

that depends on the boat.

legnth, hull integrety, are factors.

if the hull is strong enough to handle it i would use a different type of flotation......

Re: Deck repair

How thick of cloth would you use and would you use 1 or 2 layers of cloth for the deck?

 

[oops!]

Re: Deck repair

total of 8 oz matt on the deck is more than enough.....if you use cloth, matt must go down first.

i would also go matt and cloth up the gunnel as a joint....6 inch overlap.

 

[pozenbaugh]

Re: Deck repair

Thanks Opps. What is the "gunnel"?

So you would just use the matt and no cloth?

The thickest mat I found is 1.5 - 2.0 ounces. Does that mean you would do 4 different coatings of it?

Sorry for all the questions.
