can it be used to fill cracks in old wood floors?

It expands quite a bit I would recommend the small gap stuff it doesn't expand

If I have some erosion under my walkway will this be an acceptable fill?

Likely not. The foam will certainly fill the gaps, but even once it sets, it's still pretty soft. It wouldn't provide any support. It might prevent further erosion, though

Is this product closed cell foam?

Hello, this product is considered open cell. However, our open cell count is far less than any competitive product you will find on the market. So once it's cured, it forms an air and watertight seal. Thanks!

Hi, no it is not, if you need our fire proof foam, I have posted the link for you below. Thanks! https://www.amazon.com/Red-Devil-0915-Sealant-Characteristic/dp/B00GY59RHC/ref=sr_1_2?keywords=red+devil+0915&qid=1564318468&s=gateway&sr=8-2
