New to TFP. Doing some research on a coping repair and ran across y'all.
Have an inground gunite pool that we renovated about 16 years ago...located in Atlanta GA.
While in the process of replacing my expansion joint, I discovered a loose coping stone along with a few areas where the mortar/grout was crumbled.
In these areas, I have "cleaned out" the old mortar with an angle grinder and am ready to "reset" the stone and "regrout" or remortar" around this stone and the other areas. See first 3 attached pics.
QUESTION #1 - What would you recommend that I use? ...portland cement? ...grout? ...latex fortified? ...something else?

QUESTION #2 - In many other areas of the coping, whiles the grout seam itself is intact, there are hairline cracks between the stone and the grout. Any recommendations on "filling" those? ...then sealing the coping? See last pic attached.

I am facing the exact same issue with my 70s pool - thanks for the tip on S Mortar. Is there any consideration when applying mortar to the Inside pool wall where the tile line should go? I need new tiles after I m done;) Joe good luck and let us know how that project goes.
