You could tile right onto the stucco, or this will work if you can keep it out of the weather.

Is there a 7.25 saw blade that would useful for getting smooth cut edges ?

Yes, a masonry blade will do just that. BUT, it will create an incredible amount of dust! You must wear a dusk mask and goggles, and cut outside. It is not recommended to cut Hardie board that way, but rather with the Marshalltown scoring knife that has tungsten carbide tips. I can understand your frustration with this slower cutting method, but once you try cutting Hardie board with a masonry blade and see the volume of dust it creates, you might have second thoughts.

I would not recommend using this without some other structure to support it. This is designed to lay on a subfloor and doesn't have enough strength to support standing on. You could probably use it on wall framing but not on the floor by itself. I am able to bend and break the 1/4 board with my hands.

Unlike brittle boards
Has an excellent bendable character to it, easy to score, easy to bend and separate after the score, great to handle, easy to screw, clean edges for great fit. I favor a dry fit first, then label each one, set aside, lay the thin set for one, secure the one, thin set for two, and so on. I have used other backer boards, but this works the best.

Used this on top of the sub floor before putting down tile. The grids make it easy to cut accurately and also help installers with nail placements. It is much easier to handle than other brands which require 2 people to carry to avoid breakage.
