aprox. how much epoxy do I need to recore the deck?

[intrim]

I have an ariel. I know no one will be able to predict exactly. but I am curious as to how much you guys have have used.

[bcooke]

A full deck recore or just sections?

[bcooke]

A quick search with 'epoxy' and 'recore' in the search parameters turned up a bunch of threads that talked quantity.

There were a couple talking about Tritons that used 13-14 gallons for nearly full deck recores. Your mileage may vary.

Nothing is more expensive than trying to save a little money.

And nothing is more permanent than a temporary repair.

Yeah, you need to be more specific on the area you are recoring. Its like asking how many marbles fit into a jar without describing the size of the jar. You will find that the price per quantity of most brands of epoxy go down significantly with the increase in the size of container. As the owner of a project boat you may just want to buy a 5 gal kit. If you do have left over it keeps well and you will inevitably find uses later.

I have the decks removed from the forward edge of the cockpit all the way to the bow. I plan on using marine ply . and baltek mat around the deck fittings.

Start with a 5 gallon kit. You'll need all of it, and possibly more, but that's where you should start.

A curious choice. Why?

[intrim]

I have a ton of outdoor plywood from various projects. I also have lots of kevlar, carbon and baltek mat. from various projects. baltek mat is a great way to increase stiffness in multi-layer projects. as stiff as carbon mat is. two layers is is quite flexible. but if you sandwich baltek in between those two layers you will build considerable thickness and it will be incredibly stiff. It seems to be a good fit for all of the through fittings, where excess flex is a common reason for sealant failure. I will actually put baltek over the whole layup to help achieve a more uniform stiffness throughout the deck to help prevent flex crack where the wood meets solid glass.

Baltek Mat is a non-woven laminate bulking material similar to Coremat.

[intrim]

how close is baltek to coremat? do I even need to use wood in the recore? Or could I alternate baltek and glass. That might really burn up the epoxy and add weight though. Any opinions.

[bcooke]

Interesting. That makes sense then.

My experience with Coremat is that it takes a large amount of epoxy to saturate it. I've not used Baltek mat and can't comment on it specifically.

Coremat and similar products only provide stiffness because they provide thickness when added to a laminate. Using them is less expensive and lighter weight than adding a similar thickness of fiberglass cloth, which would provide similar stiffness characteristics.

Laminate bulkers don't have any particular strength characteristics, and don't stiffen a given structure the same way that a true cored construction does. My opinion is that these are not really core substitutes.

You'll find a lot of Coremat in Sea Rays and similar production boats.
