Concrete floor finish at external doors

[tommyt]

Didn’t know if to put here or UFH forum. 

I’m having polished concrete floor and am after a flush finish to the patio over two lots of sliding doors. And also the front door. The doors are installed on compact foam. The frames will end up partially buried with 12mm protruding above FFL
 

I’m struggling to work out a neat way to add the 10mm expansion strip along the door frame.

 

If I leave it level with the frame and cut it back after I’ll see the top of it.

If I leave it shorter than FFL there will be a very thin piece of concrete above it liable to cracking. 
 

anybody have any ideas or photos of how you’ve done this before?  Can I do away with it in front of the doors?

We've screed as our finished floor in the basement.... I just used colour matched silicone after I cut the foam away. You can only notice it if you look.

Thanks. How did you cut the foam to below the surface level?

[Conor]

Just pulled it out, rather than cut.

Ok I see. Was it not stuck to the walls, did it all pull out or tear and leave some behind?

[Conor]

The guy stapled it / taped it to the walls, and it's not really compressed by the screed so there are gaps and irregularities... So it comes out easily enough, it does tare but still easy to rip out the bits that remain with a small serrated blade.

Brilliant thanks. I’ve stuck mine on. Hoping it will pull out easily enough after.
