So I'm at that part of the build, if I'm going to tile the floors ( going to run heat tape under them) do I need to use a paint on type of sealant on the walls? If I do what kind would you suggest? Ive built stuff before but this is first display type of cage so wanna do it 100% right. http://img.tapatalk.com/d/12/09/11/eva2u7yz.jpg
