hello beautiful people, I am currently in the process of making a rock wall (made from foam covered in mortar) for my terrarium and I want your opinion on this paint I am planning to use. I know everybody recommends Drylok but it’s a a little too expensive and extremely hard to find where I am. I was planning on using this paint or similar, I’ve attached the specs below. do you think it will be safe for the terrarium once fully cured? to me everything seems ok except for the mildew resistance properties (but Drylok has it too so I’m confused why everyone thinks that one is safe). my hopes is that I’ll use a more durable expensive paint as a base layer to protect the mortar from crumbling and use acrylic craft paint for artistic touch ups. also I wasn’t planing on using a sealer on top. what are your thoughts on this plan?

here is the paint description:
