I have to tile this foyer/entry w/6x20 porcelain wood tile its rated i believe as C1 or commercial floor rated. 3/8"nominal thickness.
The client demands it time out with their old 3/4 hardwood.
Its currently a failed mosaic over a thin mud bed on top of roughcut 3/4"x 8"cross planking....... this mudbed cant be much more than 1/2"!
The joist system is, with its span and not including the sisters rated at L/1955 OFF the charts....yet this vintage thin mud bed is failed and tiles have been popped up and grout. But it lasted nearly 70 years or so!
heres a few pics and a crude sketch of my proposed cleating of joists to recess new subfloor and build up from that. Ill now have 1-5/8+ to add cross grain 3/4" exp 1 ply uncoupled from joists, and topped with im thinking strat mat which ill tile on and easily time out with the origional floor.
The big question regardless how good my blocking /sister system is " CUT or not to cut" out the old cross planking and cleate in a recess to build up from.
Or screed another even thinner reinforced mudbed ( suicide)
The clients been educated, they understand the risk vs. reward and the wife absolutely needs her floor timed out with that wood floor.
Roberto? John? vegas? !! (vegas!)
