This is why I stick to tiling and not orthopedic surgery.

The substrata is 18 mm marine ply well secured to partition wall by screwnails at regular intervals coated with Bal sealer and two coats of "tanking" / WP1.
Hi Gavin, it’s bad enough that the substrate is ply but to have it secured with screw nails instead of screws is a big risk also.The substrata is 18 mm marine ply well secured to partition wall by screwnails at regular intervals coated with Bal sealer and two coats of "tanking" / WP1.
Locally we used / use the word "screwnails" for screws before there were such things as "threaded nails". The ply is attached with screws. Thinking that maybe this is a job - removing ply and or installing wedi board - that someone else can do.Hi Gavin, it’s bad enough that the substrate is ply but to have it secured with screw nails instead of screws is a big risk also.
The ply was installed by the builders. I removed one sheet to reroute an electrical cable to reach a lighted mirror and yes both sides and edges are primed. The Bal tanking kit packaging is still in the bathroom.Gavin did you sbr the back and edges of the ply?
This would save removing the ply. ThanksOverboard all the ply with 6mm wedi board of equivalent, and seal / tape all joints.
I stick to things I feel competent at which usually but not always involves wood as the material.I am not a tiler but know how to tile competently in the normal tile range of sizes but the large format of the tiles in this job is the reason for seeking advice. I think you are suggesting I stick with joinery/ carpentery in this case.This is why I stick to tiling and not orthopedic surgery.
There are issues with the movement of wood no matter how well fixed - even 18mm plywood.
Then you've got a paint on tanking layer which is required to hold the weight of 1200x600x10mm tiles!
Ring BAL technical and see if they would guarantee this installation.
