I'm getting ready to tile my master bathroom. I used permabase cement board. I can't seem to find any really good information about what type of thin-set to use in order to fill over the mesh tape once I put it on the seams. I'm using glass tile as my final product. I also can't seem to find any information that is Dependable about whether you are supposed to fill in around outside and inside corners on the cement board. I have a couple areas where the cement board wraps around and I've seen a couple videos where it looks like they are filling in the gaps and then a couple of others where they say don't fill in the gaps but put a skim coat of thin-set on over the mesh. Does anybody have a good answer for this?
