Fantastic and informative forum!

I removed my bathroom walls (around 3 wall alcove tub) to stud then insulated/ vapour barrier and screwed cement board to the studs. In the process of cutting the cb and installing to walls the gaps in the corners (ceiling to wall corner; wall to wall corner) are anywhere from 1/8 to almost 1 inch wide (thanks to my rookie cutting abilities). What should I use to fill these gaps or will this even be a problem when it comes to adhering the tile? Probably go with 8" or 12" tile on walls.

Thank you.

1" is way too much, I'd just get a few new sheets,

*measure twice, cut once*

Hi Jack, :)

I don't see how you can have a one-inch gap in the corner and still have the sheet attached to the corner post (stud). I think Mack is right. If it's really that bad, maybe you ought to think about re-dowing the worst sheets. :)

1" way to much to just try and fill. You should probably replace the sheet.

Make sure it is due to your "Rookie cutting abilities" and not the walls being out of square or plumb or else you will have a difficult time tiling later. :)
