I have a bunch of spare ceramic tiles, ranging in size all are 4 inches wide and length are from 1.5 to 3.5 inches. well i want to build some steps out of them for dino to climb on and get to other parts in his tank but they are very slick, was wondering if dry-set mortar would give me texture, my brother gave me a bag he had laying around. Im not familiar with the stuff so i figured i would ask you guys if that would work, then i could put some type of sealant over it. But if it will not add texture than can you guys advise me something that will do that, and what brand and type of sealant to use, trying to do this for as cheap as possible, also what can i use to glue them together? i have some craft/hobby glue but im not sure if that is working, unless it just takes a while to dry. thanks for any input people, really do appreciate it
