Hi, we are building a house, have the pad framed in for the woodstove and would like to use round river rock from our creek on the outside and up the wall. Will use something flat for the actual pad where the stove will sit. Does anyone have any experience with this, my husband is getting nervous at the thought of it even though he has done most of the house so far. Texture is being done now, so he will need to be putting rock on soon. His questions are: how do you secure the rock to the wall, will the mortar hold the rocks as you build it up, or do you have to build in portions and let each level or 2 set up?

~Thanks~
