Good sealants for grout? Help appreciated!

[rubi9229]

Hi! I'm building some some rocks for Pancake to climb on and I can't decide what kind of sealant to get. The only one I know of is Mod Podge. Is there any sort of master list for sealants? Any recommendations from personal experience (and links if possible!) would be of great help. The grouting is almost done, and then I'll paint it before I seal it.

Here's what I got:

The grout has dried a lot lighter than I wanted but I guess it's fine since I was going to paint it anyway. I'm going to probably attach some air plants to it as well (if that's okay??) and figure out how to make a nice 2D background.

AFM Grout sealer should be pretty safe to use if you want to seal it against moisture. Since you are planning to paint it, you may not need to seal it though since the paint should give it a reasonable level of protection.

Thanks! I might not cover the whole thing in paint because I was thinking of using a dry brush technique but we'll see. I ended up buying some outdoor mod podge as well as hard coat mod podge.
