Screwing down vinyl deck and pouring foam

[halvi76]

Hello all, I am ordering vinyl and glue for re-decking my boat and have several questions. 1) When screwing deck down, will a pan head screw work or is there a specific kind?( I'm thinking about it going right through the vinyl, should I use a washer? ) 2) I have bought marine-grade plywood, would coating it with glue work for sealing it ( this is what my friend helping wants to do )or should something else be done? 3) Can I pour the foam into selected areas of the boat instead of cutting holes into plywood and pouring through holes. It is a 16ft fishing boat, and is my first project like this!!! $$$ B.H.

Hello all, I am ordering vinyl and glue for re-decking my boat and have several questions.

1) When screwing deck down, will a pan head screw work or is there a specific kind?( I'm thinking about it going right through the vinyl, should I use a washer? ) The vinyl goes on last. Counter sink the panhead screws and use a filler over the top of them such as 3m5200.

2) I have bought marine-grade plywood, would coating it with glue work for sealing it ( this is what my friend helping wants to do )or should something else be done? Yes you should coat it and pay special attention to the edges. If you want to use "glue alone" use epoxy or you can take the cheapest way out and paint all sides and edges with an oil based enamel.


3) Can I pour the foam into selected areas of the boat instead of cutting holes into plywood and pouring through holes. It is a 16ft fishing boat, and is my first project like this!!! $$$ B.H.

Yes, you can pour the foam BUT you will need to use a sheet of plastic over the top and temporarily screw the deck pieces down to hold the foam down.......... really not recommended. I would suggest a hole saw and cut out round holes to pour the foam through and then re-install the plugs and glue in place. The foam being poured before the deck is down will be a monumental PITA!

iboats just recently expanded the Paint and Maintenance section (it started 3/17/2014) Boat Paint, Repair & Maintenance - Boat Carpet, Fiberglass Repair, Antifouling and they carry foam too Spectrum Color Polyurethane Pour Foam

Now if you have saved any of your old foam and it was dry....... it will become bonded to the new foam if re-installed. That will save you $$

Good luck

Re: Screwing down vinyl deck and pouring foam

I was planning on wrapping the vinyl around edges... is this not correct?? (like upholstering a chair??)

Do not wrap it. Just glue it down and actually the vinyl should extend up the sides of the hull just a bit.......helps keep the water out of the hull.

Have a look at how I did the vinyl decking on my Tracker tinny:

Using rivets to secure your decking will be the best build, they won't tear through or twist the vinyl.

Have you purchased the pour in foam yet? If not, you may want to consider the polystyrene sheet foam instead. I'm not against the pour-in foam, but there are certain working conditions that need to be met for a good installation and one of the main conditions is a 75*F + working conditions. For maximum expansion you need the ambient and materials at least 75*F and warmer is better. It's something you really want to do on an 80*F or warmer day and I notice you list your location in Wis. and it's going to be a while before you will see those kind of temps.

That's what I thought. I'm not a "Tinner" but I've seen a bunch of the guys that are and most of em Wrap the vinyl like you are suggesting. JignGrub is a good one.

LOL he beat me to it!!!

Re: Screwing down vinyl deck and pouring foam

Pour foam will be here next week, plan on heating garage and buying a respirator for fumes. The Big issue I have right now is getting out the back piece of old decking... Do I need to remove all the rivets from one side where a shelf is? Have pictures to post next that are still in camera. Thanks B.H.

Re: Screwing down vinyl deck and pouring foam

Post those pics for the best help.

There shouldn't be a lot of fumes from the foam.

What do you plan to seal your decking with? 2 part marine grade epoxy resin will be your best and longest lasting sealer.

Re: Screwing down vinyl deck and pouring foam

You can either pour the foam in first, or cut holes and pour after the wood is down. Foam expands a great deal, and if you add too much through a hole it can blow the deck out. It doesn't happen all the time, but can and does, so be careful if you do it this way. Also it typically won't fill the entire cavity, there will be numerous voids, which may or may not be a concern. The warmer it is, the more it will expand.

Depending on the job and conditions I frequently pour the foam before putting the floor down, this allows you to fill the entire cavity with no chance of blowing the floor. You just shave down the high spots before putting the wood in place.

Re: Screwing down vinyl deck and pouring foam

halvi76, I'd highly recommend you open a free Photobucket account and use it to post your pics into iBoats. Almost all of our members use this method. It's much easier and better. Once your pics are in Photobucket you just copy the IMG Code and paste it into your iBoats thread. Couldn't be simpler.

here is the picturehttp://s90.photobucket.com/user/halvi76/media/P3210002_zpsda5f0061.jpg.html not sure if it worked?? I am trying to get the back ( last ) piece of plywood off, and figure out how to get the new one in?? HELP PLEASE !!! B.H.

Re: Screwing down vinyl deck and pouring foam



Do you mean you're trying to get the transom plywood out?

Re: Screwing down vinyl deck and pouring foam

GOD BLESS YOU!!! I have been trying to get that picture up , It was driving me crazy!!! I was trying to get that last piece of plywood out and it was in tight! It's out now, I cut two slits so it could pop up past the two pieces of metal that hold storage compartments, was there an easier way?? I still have to put the new one in and if I don't have to cut it I won't, however as it stands, the two slits will be covered up by the back shelf. Questions,(1) the plywood will be cut soon, use three coats of sealer, or glue? (2) the wiring in the boat has been worked on by 3 different people before me (works but not sure how) and I would like to start over but am a Chef / School bus driver so hopefully, someplace, you'll direct me to the easiest post. I only have lights, bilge, live well, trolling motor and anchor mate. Figured out the 3-way switch for the lights last year. Thanks B.H.
