Durock vs. Hardiebacker?
I have heard various people say Durock is far more superior than Hardiebacker, but it seems to me that hardiebacker doesn’t chip as much and particulates don’t break off.
Hardiebacker seems to be tougher but I’m not sure.
Also, regarding water, a friend of mine swears that if you leave the two, durock doesn’t fall apart and hardiebacker does. I haven’t found any anecdotal data for this with anyone else.
