Question: from some posts that we have had recently my mind went to a problem that I have with craft foam. It absorbs water and then sinks. Is it just me? If not, what should I do to make it water resistant and still float. Is there a better alternative? (I hope I can do something to treat it because I have half of the free worlds supply of it.)
Hi Mike,
Craft foam is the pits, IMHO. There are a number of better alternatives:
1. Rainey's Float Foam cord
2. The thin white packaging foam that has the visible bubbles, color with art markers if needed
3. The soft white slick-surfaced foam that is used to make life jackets and floatation belts
4. For some purposes, the hard and dense foam used to make flip-flops
5. Foam from popper blanks
All these foams will float better than craft foam. The disadvantages are that more cutting and shaping may be involved for certain uses compared to craft foam, and fewer colors are available off the shelf.
You could treat what craft foam you have with Watershed, but I don't think it is worth the effort, expense and smell.
I will try to uncover a long post I made on the subject several years ago.
