My neighbor told me to stop back-buttering tile and I fought him for a month before I tried it his way
Been doing tile work for about 6 years and always back-buttered every single tile before setting it. My neighbor across the street did tile for 20 years and kept telling me I was wasting time and making a mess. I finally tried not back-buttering on a small backsplash job in my own kitchen last spring. Turns out my thinset mix was always a bit dry because I was compensating for the extra adhesive on the tile. Has anyone else had to unlearn a habit they swore by?
I was reading that same thing in an old tile forum actually - some guys swear back-buttering is only for big format tiles or if your thinset has skinned over. Makes sense about the dry mix too because I always added extra water thinking it would help the butter stick better.
