Re: Recore Entire Deck

A lot more work to do, and off topic - but finally in the water.

Were you using true fiberglass "cloth"? A better choice is 17 Oz. uncrimped fabric - often called Biaxial. It drapes nicely, wets out nicely and doesn't move around as much as cloth when you roll & squeegee it. It also builds thickness faster.

Re: Recore Entire Deck

I am done fiberglassing!!!!

Conquered major delays:
- I messed up my knee fooling with a tarp tore my PCL (sort of the opposite of a ACL)
- Working in 90 to 100 degree weather with rain almost every day

I have learned that:
- Working with fiberglass cloth is why cuss words were invented. Fiberglass cloth will NEVER lay down the same way twice.
- CSM is a breeze if you dont mess with it too much once down. Rolling heavy CSM too much at the wrong time causes it to break up on your roller and make an awful mess.
- And today I discovered that Love Bugs are attracted to the smell of Polyester resin. Arrggg!!!

I would do it again- but never ever ever ever ever again in the summer time!!!!

P.S. (I did not reuse the old skin - it just didn't look like it would fit right. I laid all new material)

Re: Recore Entire Deck

This weekend I will be finishing up the deck repair. It was a big job, but not nearly as scary or messy as it sounded initially. Advice you guys gave really helped with that. Florida summer weather was really the only bad part about the whole deal. Now that I have all these really cool tools, (and a little bit more experience) I think I might be looking to pick up another distressed boat this winter and do this again!

Good luck! The multitool is far and away the best choice for this job. There's a tendency on some of the cheaper versions for the blade to get pinched in the deck core & vibrate loose. I put a lock washer under the retaining bolt & that solved the need to re-tighten the blade every two feet. Hmm... you've got me motivated to carve out another section of our sidedecks. Ugh. You would not believe the state of the genoa track backing. So rotted, can't tell if it was solid fir or plywood!

Re: Recore Entire Deck

Well I think I will start with one of these areas, then confirm what I think is under there and go from there. The bow and the center axis seem to be solid glass and the rounded edges are 1/4" solid glass. Seemed like the safest place to start?

(The supply buying is a little confusing. Here in Florida there are several local sources of resin etc. but I am going to have to go carefully on that.)

I really like Gougeon Bros.' West Systems epoxy and use it for critical applications, because I explicitly trust their standards of manufacture. But for bulk work like this, you can save 50% by purchasing discount epoxy (I wouldn't even consider polyester resin for this job.) There are a number of formulators out there -- and that's all they are, because everyone buys their resins and hardeners from the same two sources. They dilute the hardeners and sometimes add solvents to adjust cure rate, flow out, and mix ratios.

HOWEVER: Some of these discounters supply (or sell) pumps for their epoxies that are not metered. That is, they don't dispense the correct amounts of resin & hardener on a one-pump to one-pump basis. Even if they are different colors, or have different numbers on them, the pumps are identical. YOU have to count the right number of strokes, like "Three resin, one hardener." If you are used to metered pumps from top-end vendors like West or MAS, there is room for heartbreak here.

Do not ask how I know this.

All that marketing is expensive. Their stuff and prices may be O/K for small jobs and hobby stuff but when you get to an industrial strength job like a deck recore the difference in prices can really add up. When I did my deck it cost me about a boat buck - it would have been way more than two if I had used all WEST products.

For a job like you are contemplating, I'd forget about pumps altogether and go with graduated containers for mixing - you'll get RSI pumping that many little squirts.
The other sellers are kinda freeloading off WEST's huge, decades-long R&D project. The Gougens test to destruction all kinds of bonds and coatings, just to see how their products perform. They put ungodly dollars into formulating high flexural-modulus epoxies like G*Flex and the spiral nozzle caulk tubes that mix on the fly. They standardized the use of so many additives, curing schedules, and resin/fabric design work, all with an eye toward building and repairing boats, that they could be said to have invented the discipline.

Aeromarine has a basic website and some cheap-ass Chinese pumps.

So I try to honor WEST's public service with a hundred bux here and there; if nothing else, it's nice to have them around to ask questions of, and to have their product line available locally in an emergency. But when I'm buying two or three gallons at a time, I choose one of the discount houses. These guys will be seeing a chunk of my bank account next month. I've read the formulators' markup on epoxy runs 7 to 15X -- which I agree seems awfully high. But then, I ain't in the business & hesitate to tell people how they should price stuff.

Measuring cups are certainly faster than pumping. If you want real accuracy, speed, and the ability to mix exactly as much epoxy as required, portioning by weight is ideal. A digital scale in a big Ziplock is your friend! Weight ratios are not always the same as volume ratios tho, so you will need the exact numbers from your formulator. IIRC, WEST with special coatings hardener is 3.5:1 by volume, 3.7:1 by weight.
