How long does it usually take for the mud to dry? I don't have my Kerdi membrane yet anyway; I'm just curious. I had some left over mud that I balled into baseball-sized clumps for easier disposal later- one of them appeared to be dry this morning, so I picked it up and squeezed it, and it crumbled apart completely in my hand. It appeared to be completely dry inside and out, but I was surprised at how weak it was. I used the recommended 5:1 sand to portland ratio... is it possible it just wasn't dry enough, or maybe it's because it wasn't packed as firmly as the shower pan? Sorry for the probably-lame questions, but I'm nervous that my mud base is going to end up weak and need to be torn out (would make the removal easy I guess).
