I am just about to seal my DIY structures and I'm debating on what kind of sealant to use. I used mod podge on my last set and the poop seemed to stain it and hard to scrub off.
I found this Epoxy Acrylic Sealant and I was wondering if this would work and it if works, would it be better than mod podge
You could always buy a small container and test it. Seal something of the same material, try putting it under heat after it dries to smell if there are vapors, flaking or any adverse reactions. I have never completed a DIY project far enough to give better advice. Perhaps this will bump and give you a second round. :wink:
