Rant: 18 months into my own bathroom reno before I realized I was tiling wrong
I was laying 12x24 porcelain tile in my shower and kept getting lippage no matter how much I leveled. A buddy walked in, watched me for 2 minutes, and said why are you back buttering the tile like it's a mosaic, you need to burn in the thinset on the wall first. Has anyone else had that ah-ha moment where one simple trick fixed their whole tiling game?
