Rebuilding my boat

What is the best foam to put in the bottom that want absorb water

[KDAVID1]

the type you mix and pour in is what you want to use.

Where can I buy it

[canebreaker]

The store.

Hardware store.

You can use the stuff in the can. Have a board to float it out like concrete if needed. Try not to have to bust the finish, that's where water will get into it.

K David is correct on the pour in type, it is the best, but if ya want a little less cost I have subfloored a boat with the pink type that is used in building houses. It is pretty water proof also. I think its made by owens corning.

The mix type foam will absorb water, it is not a closed cell foam....If you don't believe me ask anyone that has ever rebuilt a tracker boat.

Use the closed cell foam in the 4'x8' sheets that you can get at Lowe's or HD. It is usually blue and sometimes pink, even the white perma-r foam board will work.

I thought it should be close cell to thanks

I rebuilt my front deck a while back some one before me had used some kind of spray foam under there. This stuff was waterlogged and weighed a lot also it had sealed off the channels that allowed the water to flow to the rear of the boat to the bilge pump. Once this junk was removed the front end was a lot lighter and planed out easier. If you can find some old throw type boat cushions or old life vest at garage sales the foam in them is great for stuffing in nooks and crannies. These projects are a lot of fun and make the boat safer but sometimes can be frustrating. Have fun and good luck.

The blue board will not soak in any water . I got some catfish jugs made out of 2" stuff still don't soak any water in . It is made by dow chemical .
