So I've been working on a new tank for Doug these past few weeks, and I have practically everything sealed, yet I realized there are a few spots that haven't been (mainly undersides of things like ledges etc.) and I was wondering if that would really cause any problems or not. It's sanded grout that I'm sealing, and it's about 5 layers of grout to what wasn't sealed with Mod Podge is pretty solid anyway. I've been looking things up online and I can't see what sealant is even for besides waterproofing.
Here's how it's looks:
And here is the man himself Doug enjoying it (these were taken before sealing btw):
I too have undertaken the same project, and this is an excerpt from a website I found when I was making mine:
"You definitely want to seal the grout. You don't want the lizard ingesting particles from the grout. The sealant also makes your life much much easier, as it is the sealer that enables you to clean a pet's poop out of the reptile habitat very easily and without eroding the grout structure. Without the sealant you would eventually wear the grout down to the polystyrene."
I also would think that when you spray the habitat for him to drink the water droplets, the water would run down to the bottom of those areas where it isn't sealed, giving a greater chance that he would ingest some grout particles.
