Tiling over Hardibacker adjacent to drywall

My wall is 1/2" drywall, abuts up against the shower 3/8" cement board. I want to run continuous tile across both. How to build up the cement board the extra 1/8" for even tiling??

1/2" durock or permabase would have got you an exact match. I would float it with wide mesh tape and thinset not joint compound. Personally I rarely use the thicker Hardie, although I use the 1/4" all the time. For 1/2" I use the others mentioned.

Another option is 1/2" Denshield. I agree, a better product would yield better results.

I didn't even know they made 3/8" cement board. Since it hasn't been tiled yet I wouldn't think it would be that big of a deal to tear it out and replace with 1/2" It might be helpful to tell us more about the total project.

Thank you!
I'll be replacing with the 1/2" Durock since the tiling hasn't begun yet. It's only one small section at the end of the tub/shower.

Installed brick veneer on drywall and now grout won't stay in spaces

MoniqueChris on Jun 13, 2016

I'm new to any kind of brickwork, but I put up brick veneer on a large wall in my kitchen and above the cupboards with stone-veneer adhesive. I didn't put up any mesh or anything beforehand. Then I tried to grout with regular tile grout and then tried regular mortar and nothing stays in the spaces. I now know what I did wrong -- there is nothing for the grout or mortar to hold onto because of the smooth surface and probably also because of the shallowness of the bricks -- but I am stuck with it and need to get something in those spaces to finish the project. It doesn't have to be a strong material, as it has no load to bear. It just needs to stay in the spaces. I'll take any ideas, crazy or otherwise, to get it done. Thank you very much.

I hope to be nearing the end of mudding. I am planning on orange peel and knockdown textures. I have sanded all knife marks and all edges of mud joints so there is just a smooth edge. I have been going around with a 12" knife and checking horizontals for areas that light passes thru and filling the lows. What else do I need to do? I may work on my butt joints more so they feel less like a hump. Do I need to seal the drywall or just spray the mud and prime over it?
