durock was wet when purchased now looks funny
So I wanted to run this question by the group before I start using these boards. We purchased 3 x 5 sheets of durock from Lowes and it was wet. I guess they were storing it outside and we had a pretty wet summer. So I put it in the garage and let it dry out. Now the durock has a white haze all around the edges. I assume that is just the lyme in the portland cement. But thats just a guess. I don't see a problem with using it but want to ask first before I put it up. I am planing on using Kerdi over top.
Also I am going to replace the pink insulation in the walls with new or maybe I will just add to it but I know I need to break that paper cover so I don't produce a vapor barrier. How much should I cut up that paper or should I try and remove the paper? What are your thoughts on doubling it up? TIA
