I’m doing the tiling on a self build
He’s spending 120k on tiling Lots of curved walls As normal all the floors tiled after the walls I’m only using a grinder to cut all of these
Just use an angle grinder with a specific blade
Ive a couple of no dust cutters at my yard But no one ever uses them
Most prefer a 4” angle grinder
The blades are that good now
We have a Mitsubishi
Seemed popular I’ve had four Mitsubishi pickups from new Always reliable
Our neighbor has a Panasonic Installed on top of a flat roof in a very exposed place
Hasn’t missed a beat since 2008
To be fair
I tile a lot of commercial jobs in traditional screed that have no decoupling Matt and most liquid screed are tiled within a week of being poured
Hardly ever any problems with modern adhesives
Your probably going to need to engage a SE So I’d get a survey done before speaking to BC So that you can tell him what remedial measure If any you will take
Your Architect will air on the side of caution As will BC
A rule of thumb for PB weight and thickness is 400 centres 12.5 boards
600 15 mil boards
MF 1200 grid = single layer PB
800 grid = 2 layers of anything
Not a Google technical answer
But a rough guide
