Can anyone tell me how to install flexcell fibre board in concrete up against a wall and get a nice arrised edge on the concrete up against the flexcell with the fibre board left down for the thioflex?
Hope you understand that!

with great difficulty dan
need to fix the flexcell to the wall then maybe use some 6mm ply to trowel against
1 of my pet hates this detail and i have done scores of garage floors without it and none have cracked yet
looks pants with flexcell IMHO

i agree, one guy said to lay conc over it and then go along with a bolster and the fill with the thio, yes but doing it that way you dont get an arrissed edge and it will look a c**t,
Like you say i may fix some batten or something similar to the wall above the flexcell with light screws, round the concrete off to the batten and then somehow break the batten out??

just stick it in and leave it like 25mm below finished surface level, then use some plastic conduit or what ever you have to use as a shutter, wait till its at the right point then arris the concrete then seal with your sealant then it depends whether you seal right uptp surface and use a bit of 15mm pvc pipe cut in half etc to arris the sealent so you have two arris opposite or just fill up to the bottom of the arris. is that what you mean or you want a straight edge on the sealant and an arris on the concrete?

yeah i get you, use a bit of square or rd electir conduit ontop of the febre board, arris your crete then use a float as a moving shutter when you seal it
