Give me the bad news. Am I chiseling out foam and repouring a tiny amount of self leveler?
Contractor is doing the job himself rather than using a tile guy. Area on the left is kitchen and it will be tile. Area on right will be carpet. He put up a self leveler dam to hold in the henry 555 to prep the floor and make it level, which was good. But then he added a layer of spray foam like you would around the walls where there is no traffic to stop any leaks.
Walking around doing the tiling and immediately all the corner cement chipped away to reveal this foam. I can't see how it will support the carpet transition strip, then the mortar, then the tile.
My gut tells me we have to chisel away all this foam, scour out the lose cement like you would a root canal, put the dams back up, then pour in more henry's to put it how it should have been: Just a dam there and no foam (or foam on the OUTSIDE of the dam.
Alternative: When people are transitioning from a low carpet to a high (it will be about 2 inches high tile area), do they permanently screw down like a 2X2 at the self leveling border and then ramp over it with Henry feather patch (or any cement type patching agent_?
