Retrofitting china cabinets?

[Bogertophis]

Didn't think I'd get that kind of response.

I don't know much about sealants and everywhere I look about them always says the same 100% silicon sealant or epoxy glue answer. Haven't really seen anything for what to use for full wall sealants.

You're confusing "sealing" corners with sealing surfaces. Silicone aquarium sealant is thick, not spreadable- it's used to glue & seal corners so water doesn't leak out. Non-toxic once dry.

In a cabinet, you'd want to seal (coat) all the sides, bottom & top so moisture doesn't affect the wood, then you'd also want to "seal" the corner crevices (in case the water bowl got spilled, for example- you wouldn't want the cabinet ruined). I'm not sure if any "marine varnish/spar varnish" products are pet safe- probably not. Most waterproofing products are not made for use with sensitive pets- they're made to put on outside fences, wood floors, boats & decks- stuff like that. A quick search found this https://www.mychemicalfreehouse.net/...finishes.html-
it sounded promising but they're talking about human homes, not small pets, so don't go by their info. That's why I suggested the products for sealing ponds- those products are designed to be safe for fish & turtles, etc.

Search for "non-toxic waterproof sealant" & make sure you read all the fine print- you want something easy to paint on all sides. I've used waterproofing before- I think it was Thompson's water seal. It was easy to work with, dried clear. But depending on how/where it's used (how much moisture it's exposed to) it doesn't last forever, it needs re-coated in about 4 years. Just pulled this up:

Is Thompson's water Seal non-toxic?
Environmentally safe, will not harm plants, pets, fish, livestock, humans. Contains zero volatile organic compounds (VOC). No toxic fumes. Seals and protects with single application on most surfaces.



Bottom line- these projects take planning & research, so do your homework.
