I purchased a pe super le wood stove. It only requires ember protection. I know the materials I am going to use but not 100% sure about adhesives and what not. Looking for advice on how to do this properly.

Hearth construction is i removed carpet and padding down to subfloor. Building a 2x4 frame topped with 3/4 plywood. 2 layers of Hardee cement board and finished with porcelain tile.

Do I need liquid nail along with screws just for extra securement for plywood to frame.

Do I need anything between the Hardee cement board and plywood or between The 2 layers of Hardee board or should all of that just be screwed together.

Last I should use thin set motor for porcelain tile followed by sanded or non sanded grout.

This will be permanent and last 30+ years. So I want to build it to last. Any advice would be greatly appreciated on how to construct this with the materials I will be using is greatly appreciated. Thanks

Glueing the plywood down certainly won't hurt but probably won't add anything either. If you screw it properly you shouldn't need anything under the cement board either. You really only need one layer as well.

As far as setting the tile yes thinset and sanded unsanded depends upon joint thickness
