Floor prep advice

[Paul R Cox]

Hi there, I have a shop floor to price up. It's about 50m2, currently vinyl and they want it tiling. It's a suspended floor with a little bounce here and there so I'm wondering which prep option to go for. I could possibly ply over for some added rigidity then ditra over that? The main problem there is that part of the floor is concrete so how would the ply fix to that area? And what thickness ply required if using Ditra? Thanks in advance for any help.

Personally I'd rip up the vinyl but 18mm ply will do ya and Ur concrete area drill and plug the floor before laying trowel little adhesive underneath the ply and then begin to screw in place

Thank you, I was leaning this way but not certain about height implications. I guess if it needs to be 18mm, that's that.

cement board floorboard area, then self level scread area to same height. Bare in mind that the joint between the two will need an expansion gap.

Thank you. I presume you mean 6mm cement board? Does this offer the same rigidity as 18mm ply though?

What is the ditra for?

If the floor is “THAT“ bad, then you would be better off strengthening the floor first.
ie......lift floorboards, If need be, add noggins.
replace with 18 or 22mm ply, overboard that with 6mm cement board, then self level screeded area up to the cement board.
