Title: Bad Foam
Post by: Tio Pancho on May 08, 2009, 08:21:00 PM

So we finally got around to working on Bebo's boat again. Quarter stringer Hondo (?). We cut out a bad section of glass on the right side of the engine bay and found some bad foam.  :mad: It is pretty wet and has some pretty deep voids. There is also another deep depression in the fiberglass right next to the area we cut out. Do we need to remove the bad foam and replace it, or can it be left out to dry and somehow repaired?

I would cut out/remove it (the foam) and leave the "void" I would use a different type of floatation when you go back Tom

That foam will never dry out.Cut it out its cancer.

X2, won't float either. I have bought the styro blocks from Tap plastics and made floatation to put in the hollows and used their 40:1 closed cell foam in the gunwales to make it float when submerged...

So we ended up cutting out a bigger area of the foam on the right side because we could see that the glass was bad and the foam farther back was bad and wet. :mad: We are trying to do this on a low (insert "No") budget due to the fact that I have been out of work for 4 months. However I am trying to keep Bebo motivated and moving ahead. My question is this - Can we use the expanding foam cans to fill the voids? I tested them today and found the following: It sticks very well to almost anything. It appears to be a closed cell and has a very positive buoyancy when I squeeze it and held it under water. It also sanded well which will allow me to shape it as required. I have a couple of cans of this on hand which means that I would not have to buy any foam. Watcha think?

If it were me and you have the same budget I use  :banghead:, the cans of foam are gonna cost a bunch....If you do this, use the window/door stuff, it makes less pressure than the crack filler crap, I would get a hold of Tap plastics and try their 40:1 expanding foam, measure very carefully and short it by 10%, this stuff is super strong and can bow the bottom of the boat..

My recomendation would be to forgo the foam and get her together...You can always drill a hole in the floor and foam it later if you really feel strongly about it......Just my .02c

I dont think most of the boats that are here are running any foam in them at all. Fix the glass/wood and move on.

Like GT said, later...Drill a hole and put it in later if you really want it.

Throw a couple inflated beach balls under the deck.  Or someone has suggested using ping pong balls  :screwy:

I put an inflatable boat under the deck. You can get 'em a Walmart, K-mart Etc. they're kinda pointed in front and fit pretty good And you can get 'em out in a minute.
