## Questions & Answers

**Q: Can you use on basement cracks**
A: The foam is made to fill voids in boats for flotation and is not structurally strong.
That said, it will fill cracks as long as you're not depending on it for strength.
After it is poured, it will expand. It pours like water so it might be difficult to get it where you want it on vertical walls. Easy to pour on a floor crack but not strong enough to walk on.

**Q: What is the flotation range for the 2g kit? will it support 1500 to 2000 lb floating dock?**
A: 1 cubic foot of 2 lb. Polyurethane close cell foam will float 60.2 lbs.  per US Coast Guard regulations of Flotation. So by the their formula it should float about 480 lbs. of weight. 
So no  you would need 6 2 gallon kits to float just the dock. That's not counting any weight of people that stand on the dock ....

**Q: How much does this cover?**
A: A two gallon kit (1 gallon resin + 1 gallon activator) will yield 8 cubic feet which is equal to 59.84 gallons. 1 cubic foot equals 7.48 gallons.

**Q: Can the 2lb product be used to fill the void in my kayak made of high-density polyethylene or will it deform?**
A: It should work just fine. Use a smaller amount at first and then mixed more as needed until the void was filled.  I was not not sure how much
it would expand so I started with a smaller amount .  It expands and hardens quickly. I don't think it will deform your kayak, but it will expand out of any cracks and holes, but you can cut off any foam you don't  want.
