laminating on new glass

[BLueOne]

Hello All, i really like reading all the different PROBLEMS that people are having. I was wondering if any one could help me with a question, i bought a brand new hull 25' by 9'6" southwester. I personlly dont think there is enough fiberglass in the hull. I would like to add more, can I after I grind it down smooth and how much 1708 db can I put down at one time .Will it be as strong as the first laminate Thank you.

Hi Blue one, I bought an old boat that was in great need of reinforcing. I ground off all the old paint inside with a 25 grit disk, wiped it down with acetone and built up alternating layers of chopped strand mat and 24 ounce woven roving. In the way of the chain plates I added about 1/2 inch in layers, a layer of csm and a layer of cloth and allowed that to cure hard, about 2 hours, and added another layer. I worked alternate sides for balance, Polyester resin does shrink some(not a whole lot) but I like to keep things symetrical. I also lined the entire hull from the turn of the bilge to the cabin top and from the companion bulkhead to the bow with 1/2" Airex core and glassed over that. So add as much as you like, keep it balanced, work carefully and safely, and when you are ready, ask me how to apply fiberglass overhead without getting wrapped-up in your work.

Blue One,
I have a question,
Did you buy a bare hull with the intention of completing it yourself?

Thanks for the advice, So what you are saying is that i can lay down more glass onto already dried glass. yes I bought the boat to comm fish with it . I have built a 1969 north american, stringers, decks and bulk heads . but i used mostly epoxy. it turned out great but expensive . When I bought this boat it has about half the thickness of the north american thats why i want to add more laminate to it.

If you have any doubts about your technique, take a small square of plywood, say 6", and laminate one edge of that to the hull in a place where you can get hold of it with both hands. ( it should look like you put a piece of duct tape on to keep it in place).Let everything cure and try to pull it off. you should end up tearing the glass. satisfied with that, grind off the lump and get started.
