We're building a hearth pad by laying flagstone on cement board over plywood. The installers recommended using S type mortar, but the folks at Lowes are recommending thinset. Are both appropriate for this use? What are the pros and cons? For the S type mortar, there were two "S type" products on the shelf at Lowes- S type cement and S type mortar/stucco mix. I'm guessing I want the second, is that correct? Or am I looking for something completely different?
Also, is it necessary to use grout over top of the mortar, or is that more for aesthetic purposes?
Thanks to everyone who replied to my previous thread! This forum sure is a great resource.
Thanks,
