It's urethane foam, which has a long history of health-related issues for humans, and if it ever gets near an open flame or catches fire, be somewhere else. It can release cyanide gas.That foam you have may be an issue. Their tongueS are very strong and have suction. So if he shoots his tongue out to get a feeder that is on that foam he might get some foam too. I have no idea what its made of but it cant be good for his intestines.

I (naively) worked with and around it full-time for 3 years, and I'll never use it again.
IME, problems can occur at one or more of many stages—manufacturing, mixing, transportation, storage (respect shelf life) conditions, application, wear & tear (UV will degrade it). Some of this makes it hard to prove causation, and easy to shift blame/responsibility to the end user. IMO, it's more prickly than chameleon husbandry.
I've used Flex Seal (after much research) on my Missus' tortoise table. IME/O, spray or liquid depends on the situation. Think about whether claws/nails might come in contact and scratch through. Liquid is much thicker and multiple coats will hold up to clawing/scratching better than thin spray coats. If no possibility of scratching through it, a couple/few coats of spray should be fine. I say multiple coats because there can always be pinholes, thin spots, or even gaps, so 2nd/3rd coats are more likely to fill.i see these commercials about a rubber sealant that you can paint on. It might work. Also all raw pine wood needs to be sealed.
I have not used Drylok, so no experience/opinion either way,.
