fiberglass decks??
i removed my teak decks now i have alot of holes from the screws. what would you all recomend; filling the holes and sanding and paint and call it a day? or adding adtional layers of fiberglass ontop of the existing decks.

this is on a '81 albin with molded decks with plywood core. no deck*beams.

** Well, it all depends on whether or not the coring is in good shape IMHO.* If you've got no rot, I think just filling the holes would be alright although the teak DID add some stiffness to the original build.* Just my $.02.

This is true although the teak paint job ( overlay) was an extra and not part of the stock boat.

AS a minimum I would foll the holes with epoxy , and have a heavy friend walk about on the deck as you observe where and how much flexing there is.

RE: fiberglass decks??
if there is flexing in some areas what would you do for those spots? ive been on fiberglass decked boats before that has SOME flexing when you walked on them so how much is too much? not looking for added work time and money for adtional layers of glass that isnt needed.

RE: fiberglass decks??
I think adding 2 layers of glass would be a good idea. It would probably make it easier to get a nice finish once you filled the holes and add some stifness.

RE: fiberglass decks??
fotoman, have you removed you teak?

RE: fiberglass decks??
I have not yet. This will be a Fall project since the decks are still solid and not leaking too much. Unfortunately, I don't have fiberglass underneath. The teak was laid on plywood so I'm looking at a much bigger job than you.

On the bright side I've been taking a class on fiberglass this winter and I now feel a lot more confident about doing the work myself.

When we remove a teak deck and replace it with a painted nonskid we put down a layer of 1 1/2 oz mat and the fair that with bog. This insures that all of the screw holes are sealed. If you fust fill the holes with epoxy you will see some of the through the paint and it is probable that some of them will leak. David

RE: fiberglass decks??
My vessel under the previous owner, had the rotted teak decking removed by a timber boat-building yard, and instead of going to the extreme and unnecessary extent of trying to gouge out all the old dampish core and replacing it, just sealed over it with fibreglass cloth/resin and then a thick layer of treated marine ply, then more fibreglass layers, finally with non-skid finish.. Worked well - no moisture ever came thru (now 10 yrs ago), and still nice and stiff deck.

RE: fiberglass decks??
Your not going to accomplish what you want by just putting some epoxy or resin in the holes and painting over it. The decks will flex and the filled holes will open up and leak again, perhaps not all, but enough to create the same issues you are trying to correct. You will need to either grind down each hole and cover it with a small fiberglass patch, really a pain, or lay at least one layer of glass over the entire areas, a correct solution, and take care not to sand through at the holes. Do you really want to go through all of that work to simply find you still have a problem? Chuck

"or lay at least one layer of glass over the entire areas, a correct solution, "

Good but will require EPOXY resin to actually be worth doing.

I would use 3/4 oz chopped strand MAT as thicker will add cost/ weight but very little in stiffness.

Use epoxy compatible CSM.

RE: fiberglass decks??
I have a hard time beliving that the decks will flex enough to open up the
screw holes. I've read from other boatyards that only fill the holes.

Remember the deck is actually a PLYWOOD deck ,

keeping water out is the only chance of some longevity.

RE: fiberglass decks??
well its a MOLDED FIBERGLASS DECK, i dont belive its the same as capt chucks marine trader. it is cored and my core is in good shape because the teak wasnt leaking MUCH. one spot in the aft trunk.

Why Epoxy and not regular polyester resin?

RE: fiberglass decks??
west epoxy will not shrink

Have you considered Devinicell Not sure of the spelling.*
looks like green celular foam. remindes me of that stuff florists use to stick the flowers in for arrangements.*A 1/4 in sheet and 3/4 oz matt. Super strong and will never absorbe water like plywood. Will give you all the strength you require.

albin43 03-16-2010 08:59 AM

RE: fiberglass decks??
Im not looking for more strength. Just to fill the holes
