Brick Steps

Building two riser brick walkway coming from my backdoor. Will follow above instructions, but wondering if you know how to pu the thin grey slab of concrete along the top of the bricks and mortar that is popular today. It might be granite, but it goes right on top of the bricks. thanks, Bob

Bob,
Sorry, I have no clue what you are describing.

I think what our friend is trying to describe is a blue stone tread. Blue stone treads are about $40 for a 3 footer and are available at a masonry supply store.
Installing a blue stone tread just takes normal mortar joints, "paint" a watery mixture of mortar on the bottom side of tread to create surface tension with mortar, gently and evenly press tread into place, hammer with rubber mallet to fine tune, slight slope for water drainage, and your done. Caution though, when placing tread 2 people must gently, evenly and perfectly put it in place. Anything short of perfection and your better off removing all of the mortar and starting over, rather than try to chisel it out after the first winter when it slides off the step. Also, don't forget the mortar seem between the brick risers and the bluestone tread or the first freeze will unseat the tread and your back at it with the chisel wishing you'd hired a mason.

You say "Do not use traditional brick mortar" and that you use "a mixture of fine sand and Portland cement". I thought that was what Sakrete mortar mix was! No?
