Its on trailer house with wood for skirting and they want a mason/stone look. Best I can figure is I should staple tar paper up, staple chicken wire next, then mortar a surface coat, and last mortar the individual stone pieces from bottom to top? If I missed anything please let me know. Oh, also I was going use that adhering compound in the mortar. The stone/rocks is from some molds that I got off Ebay and made up a huge amount.
