Type S mortar to tuck?
I bought your video and I felt like it really set me up well for the project. The stone is almost cut and I am getting ready for the mud work. The mortar on the adjacent house rock and brick work is type S mortar. I want to match this and tuck point the flagstone joints with type S. Should I use the portland I-II mortar per the video to set the stone and tuck with the type S or should I use type S for the whole project? How much water and sand should I use with an 80# bag of type S mortar?
