Re: What did my wife get me into?

The plan is to get all the wet/old wood out. What is throwing me is the metal under the deck. Is it just for the seat? Should I cut it out? Why is it there? In all my reading, I've never read about metal being under a deck like that.

Re: What did my wife get me into?

hello....

i was asked to jump in here.....i actually thoght i had allready replyed to this one.

ok,,,,(edit...sorry for the bad spelling but im at work waiting for glass to cure at -8 degrees)

1.
take all the wood out till its dry.
even if this is a full section of the deck under both seats...the wood is wet...it will rot.
grind, cut,...just remove it. get rid of it. (i dont care if its plywood or not...its still a fibeglassed reinforced product)

2.
dont know what the metal is.....but i would just think it is a cheap back up for the pedistals. dont worry about it. :cool:

3. after the wood is out....you will have a niced hole in your deck. take core samples of the foam in the hull. if wet....(at the bottomclose to the hull) read bob vt's comments).

4. i am guessing the foam is not wet and you just need to replace the deck due to bad care of the boat.
around the entire perimeter of the cut out area....place fiberglassed gellcoat reinforced flanges. (the flange is a "lip" to place the new deck on).
just screw them in from the top side. this will give you a 2 inch lip to place your new deck on.

5. make a new deck.
fiberglass both sides......now....here is the trick.....the area under the pedistal seats must be re inforced with either thick ply under the deck surface...or any other stiff material you can put under there. i like the diamond plate idea, but im also guessing this is what the metal you have found was supposed to be for.
the area to be reinforced must go at least one foot forward and aft of the seat base.

if the area is directly over the stringers...post here again and we will guide you from there. i would forget the plastic stuff.....go cheap...tryed and true....no need to get crazy and epoxy the entire hull, poly will be fine. use unwaxed resin for the surface or surfaces that will contact another fiberglass/gellcoat surface....but add wax to any underside surfaces.

place the new re inforced fiberglassed plywood in the hole and let it rest on the flanges you have allready glassed into place. and screw the deck on to the flanges.

make a peanut butter mixture.....(just search peanut butter or use the index on my thread for the directions to making this stuff) and smear it into the crack around your newly installed deck. let cure

grind the deck so its flat at the joints/edges.

using 2 layers of 1.5 oz csm amd a 6 oz finishing veil, glass in the new deck so that the new fiberglass over laps the old deck.
(you will need to grind off the gelcoat off the old deck edges about 4 ins around the perimeter, and grind the old plywood deck down 2 layers to accomidate the thickness of the new glass.)

after the glass is cured.....sand/fair the edges till smooth and any high points of resin in the new deck.

i am also guessing that the deck was gellcoated.
no big deal.....just re gellcoat the area with a paint brush....gellcoat is not a paint, but a pigmented fiberglass resin with wax ...so you must add an activator @ 2% just as you did the poly resin on your fiberglassed in deck.

you also might want to add sand to the gellcoat to give it a non slip surface but a fuzzy roller will give you a really good non slip surface. just goop the stuff on and roll it smooth.

wait till cure.
sand fair the high spots. so its comfy on bare feet but not so much that it removes the non slip finish.

ok....now your deck in installed and gellcoated......but you still need to add the seats and carpet.....

so.......for each hole you drill for the seat base....fill each hole with 3m 4200 then screw the base down....to be short......each hole MUST be filled with 4200....then add the screw.

as far as your carpet......i would use snap in. you can get stainless screw snap bottoms....but again.....each screw you put in the new deck MUST be filled with 4200 before you place the screw.

if you are wondering how to place the bottom snaps in the correct location....i have used chalkline chalk with great sucess....

another way is throw the rug on the deck where you want it....place weights on the corners and use a felt pen on the gellcoat to mark your spots.

there ya go bud...:)
cheers

Re: What did my wife get me into?

wow oops! 8)

You rock!

A plus for me is the boat came with snap in carpet - so I'll just need to remove the screw-snaps and then replace them. I do have a couple that are broken, so I'll need to replace them for sure.

For the flanges - what am I attaching them to? The good leftover deck? If so, is that strong enough?

Any guess how much glass/poly this will take if I do one side of the deck?

Now I'm off to read about some Peanut Butter! :D

Re: What did my wife get me into?

tes...you screw the flanges to the underside of the good part of the old deck.
just use a 4 inch flange, with 2 inches of it screwed from the top of the old deck into the new wood under the old deck.

as far as the amount of glass.....you must also glass the underside of the new deck.....one quick layer of csm is good enough.

so to calculate......you need 2 layers total of csm...one for the underside and 2 for the top. and one layer of 6 oz finishing cloth for the top....so calculate 6 inch around the cut out area x3 csm and 1x the finishing veil.
you will need about 2 gals (just to be safe) of unwaxed poly resin

Re: What did my wife get me into?

when you order ...order unwaxed and a small can of airdry.
add the wax when needed at 4%...double the mekp you put into it.

just about any poly resin will work.

see if iboats has gellcoat as well....
personally i love comp ones products....but that is just personal preference...thats all

Re: What did my wife get me into?

Got the plate out - it is about 18"x12" or so. Maybe 1/8" thick.

Once I got the bottom layer of fiberglass up, I ran into a panel or "something".

I'll get a pic tomorrow - didn't have my phone on me and had to run to work tonight.

Any ideas what the heck this is? (I know pics will help, but maybe someone has seen this before?)

I also found good wood about 2-3" from the ski locker. With the panel in there, I'm not sure if I'll have room for flanges - but I'll figure something out.

Tomorrow I'll head to the back seat and see how far the rot/wet wood goes. I'm betting it goes all the way, but will just have to see. I really hope not.

Pics tomorrow - I promise! :)

Re: What did my wife get me into?

Ok - so I think I may be lucky. It looks like I'm going to end up replacing a piece of wood from about 6" in front of the pedestal seat all the way back to the bench seats. I say lucky because I guess glastron builds these with the deck above another deck? (just guessing anyways)

From the looks of it, the deck is actually attached to the sides. I have pulled the old wood from part of it, and they have foam in behind where it was:

photo5-2.jpg


So I'm thinking I can lay the patch up under there, screw it down to the second "deck"? Then I'd lay glass over the side onto the new deck and sand it out to look factory again. Am I wrong?

Anyways, here are the pics - a little late, but I had to work almost 20 hours yesterday, so I didn't get a chance to get them.

It may be a little late now but Glastron VEC boats have a limited lifetime warranty that follows the boat to the second owner.

Re: What did my wife get me into?

Okay - so I have the hole roughed out. Need to go back and square up the cuts (my circ saw did not do a good job of cutting straight at all).

Still need to dig out some wood from the edges, but I should be able to knock that out fairly easily.

Questions: Why would they raise the deck? There are two spots where the pedestal seat mounted that they have poured some kind of epoxy, and again at the back for the side bench. Other than that, the entire deck is pretty much "floating" (I assume it is the same on the other side as well).

I'm considering going with 3/4" Marine Grade Plywood for the replacement. This will likely be a bit heavier than the standard wood, but I'm unsure if I can get 1/2" (do they make it? I haven't looked yet). The bonus to being heavier on that side will act like a ballast somewhat. I'm 280lbs, so with my wife (130lbs) and son (40lbs), it may even it out a bit. Is this just a dumb idea? Even with 1/2", it will be heavier than the wood they originally used, but not as heavy as 3/4".

Could I put the floor on top of whatever is under the floor and then build up from there? Any negatives to this?

Re: What did my wife get me into?

Looking like the replacement size will be about 30"x60" - give or take a few inches.

Looking at uscomposites for some mat and resin.

These any good?

404 Tooling Polyester Resin-Isophthalic - Getting 3 gallons (this enough?)

1-1/2oz Chopped Strand Mat (For the bottom and top of deck) - Getting 13 yards

3M-5200 (For screw holes, etc) - 1 tube

Surfacing Wax (Mod-C) - One 2oz tube

6oz E Glass (For finish on top of deck) - getting 4 yards.

Fiberglass Detail Roller - One (do I need a smaller one? I'm getting the 5" version)

Do I need to get any more MEKP? The gallons come with 2oz each, so I'd have 4oz total.

I'm planning on doing one layer underneath (1.5oz), two 1.5oz layers up top, along with one 6oz layer above it. For this process, do I need to coat the plywood with resin? (just paint it on?).

Then I'm thinking it will go like this:
1. Glass both sides of new deck with 1.5oz fiberglass - let dry
2. Put new deck in - screw into the glassed flanges - only problem here I see is that I don't have any old deck on the outside, back and by the ski locker - all of the wood was bad and it is out now. (plus Glastron put in a floating deck, so it doesn't extend all the way back). How do I attach to the sides?
3. Fill in cracks with peanut butter.
4. Sand
5. Lay down one more layer of 1.5oz, then sand
6. Lay down 6oz layer, sand
7. Gel coat the new deck - Not sure here yet, so I'm going to hold off for now until I get closer to this step.

Am I missing anything?

Re: What did my wife get me into?

You're gunna need more resin IMO. The mat and cloth will really soak it up. I'd double it

Re: What did my wife get me into?

Just went and measured the size of the cutout - it is 22x58 (so 24x60 or 26x62).

Does that change the resin needed? 3G enough with that size? If not, how much more do you think I'll need?

Re: What did my wife get me into?

I'm no pro but I did my deck with 5 gallons and it was alot more area than what your doing, and I used the 435 layup resin, dont know much about the 404.

Re: What did my wife get me into?

Doing some calculations based on the fiberglass FAQ, it looks like I will need one gallon for the 3 layers of 1.5oz Mat, and a little more than 1/8 of a gallon for the 6oz cloth. So it seems like 2 gallons would be more than enough.

I'm using MG plywood, so from what I've read it won't soak up as much as an exterior grade ply would soak up.

Does that seem right? Would save me about $40 if so. I assumed an area of 28x62, which gives me about 1.333 square yards. I'm laying up two layers of 1.5oz Mat on top, and one on bottom. Then doing one layer of 6oz cloth for the final layer on top.

Re: What did my wife get me into?

For the Peanut Butter mix, I'm looking at USComposites (already ordering from them anyways).

I've found Aerosil-Cabosil, 3M Glass Bubbles, and then some 1/4" Chopped Strand. I would use the resin leftover from the deck patch to mix it.

I'm curious how far this stuff goes. If I order 5QTs each (Cabosil & Glass Bubbles), would I need 5lbs of the Chopped Strand? And would that be enough, too much, not enough to work some flanges and fill in some patches around the edges? How much MEKP would I need?

Anything I'm missing? I think I'll be placing my order later today or tomorrow, so I want to get everything all at once (hopefully).
