Safe sealant for vivarium

[erincindyjones]

Hi, thinking about tiling and grouting the floor of my dragon’s vivarium using slate tiles. Does anyone have suggestions for a safe sealant I can use to seal the grout and tiles?

I’ve heard you can use polyurethane, but I can’t find that say non-toxic, are there any particular brands that anyone would recommend?

Also, is it okay if the sealant says “harmful to aquatic life”, as it won’t be constantly in contact with water, or should I steer away from those!

I would stay away from anything that mentions itself as toxic to anything, just to be safe.Look for aquarium safe sillicones, which are the safest and best for pet projects.
