We're giving our wood stove surround a makeover. We're going to build out the front with steel studs and cement board, then tile over it. For the cement board, does one need to mesh tape the seams and corners? I know that's required for a wet…

What should I do about excess flex in cement board that will be behind tile?

This is around a tub/shower. The studs are spaced at 24in, cement board is 1/2in. We're surprised at how much flex there is between the sheets of cement board. I'm worried that tiles may pop off. We're planning to use 12in floor tiles on the…
