Replacing a soft floor

[Bigshrimpin]

I'm no expert, but I think reusing the old skin might be too much trouble.

Go to FIberglassmans site. Fiberglassman.com

He replaced a large section of his floor with marine plywood squares and put a few layers of mat on top. There aren't any finished pics , but the next steps would be to fair level with a compound like quickfair or some other fairing compound (depends if you are working with polyester or epoxy). Finish the repair with gelcoat or 2 part Polyuathane paint. Then fix the non skid . . . Tape off the stripes and match the original height and skid pattern.

You'll be good for another 30 years

I picked up the marine plywod today at Merdith & Sons lumber. One 1/2" and one 3/8", total was $120. Any recommendations on epoxy resins? Is West epoxy the way to go?

IMHO, all the epoxies are good, but I like the Boat Builder Central stuff the best. It doesn't "blush" and you can put multiple coats on top of each other without waiting to wipe/sand in between coats. West blushes, MOS and BBC doesn't and BBC is the cheapest/best I have found so far. 85 bucks for a 1.5 gallon kit.

I think you are on the right road by going with the epoxy, I will never use glass again for repairs or stitching pieces together. The only problem when you use epoxy is what to cover it with. They say you can't gelcoat over epoxy, which leaves you with 2 part urethane, which aren't easy to blend into existing pieces, so you usually end up painting a lot to do a repair.

As far as matching what you have, good luck. If you want to spend a great deal of time, you can probably get close. While your at it, you might want to check the rest of the deck out for moisture, to make sure you get it all at once.

Make sure you get fiberglass cloth/mat without the glue. 1708 and regular MAT has a glue binder that will mix well with epoxy and prevents a good bond. I don't know a whole lot about the problem . . . but I have had some issues in the past using 1708 or Mat with epoxy. 1808 and stitchmat don't use the glue binder.

hey big...check out vectorply....

If you search E glass for 0 and 45 degree double bias with mat, you get 1708.......0 and 90 degree double bias with mat you get 1808....all their glass is stiched rather than using a binder so it seem the use the number to refer to the fiber alignment. Not sure if every manufacturer does the same.
