If you burn it, or heat it to over 1100*F (using a heat gun to peel paint or remove wallpaper), it releases a chemical that will cause brain swelling and that brain swelling can cause brain damage or death. 

Superpaint and/or Duration are good unless you need something to fill in cracks, then you can move into something more commercial-grade, like an elastomeric, block filler or even epoxy if that is the look you want but, careful, the thicker and more commercial the product, the tougher it is to get off if needed in the future and anything not water based, be prepared to toss out or clean with a chemical and not ever use it for a water based product again.

Both liquids, but chemical make up is completely different.
