I'm remodeling the bathroom and after removing all the old drywalls I installed a new ceiling (5/8 Green board, etc..) and Durock (1/2) all over the 04 walls. This is because we are going to use tiles and the pro who will install then told me that it would be ok to use the durocks all over. The only thing is that there are some occasional minor gaps between the boards. Even though I know that all will be covered with cement, I still would like to seal these gaps and also to seal the junction with the ceiling before they install the tiles. My question is, what can I use to effectively and permanentely seal off all these gaps?
thinset and mesh tape. talk to your tile guy, he will prob do it when he is installing the tile if he is going to do it right.if not i would look for another installer
