Hey. Random question. We've been putting together a rather large set up for Spike (Saharan Uro). Its 4x4x8. We are using peel and stick tile for the bottom and sides. I used liquid nails on them to help hold them down. I was smart enough to prop the sides up to use gravity to see if the tiling would stay. I've redone several of them now, and some just fell off a second time. Is there a better adhesive to use for this purpose?? Thanks!!
