Toxic Grout and Sealing...a question.

[Allhallows]

HI,

Im new here. Nice to meet you.

My question is can sealant seal in toxic-ness. I am working on building custom backgrounds for my crested gecko tank. Pics to come when finished.

I started off with styrofoam glued with "no-nails" and then coated with pre-mixed tile adhesive/grout. This grout looks like spackle, and is so easy to work with. The only problem is, it doesn't come with the anti-mold mixed in. This stuff is toxic to humans, as per the warning lable (don't get on skin, or eyes, or eat).

I already covered the grout by applying 2 coats of non-toxic acrylic paint to get the desired colors and theme going.

Now my question is this. I am going to coat the background completely with either Pond sealant or yacht varnish. Whichever I can find the easiest. This product is non-toxic and will 100% seal the background.

Once sealed, the toxic anti-mold stuff should be sealed in, correct? It won't be toxic to the animals if coated with a few coats of the sealant, right? If water can't get in, then how can the toxic parts in the grout come out? Anyone have any experience with this? As I'm sure not everyone can find non-toxic grout.

Thanks,

Mike

if water can't get in you should be fine.
