I'm pretty new to this site and I'm using mobile (bare with me). I'm starting a project for my 150 gal tank and converting it over for my tree frogs. I've started on the 3D background. But I have been trying to figure out what is the best drylok to use for this. I've seen plenty of 3D backgrounds look like rock, but I'm gonna attempt more of a tree look. Any help is appreciated. Also, if there is a thread on this sort of thing. Link? Thanks in advance!!
