Trying to lay dry stack ledge stone on a chimney chase, Have the wire mesh in place but can not get the stone to stick. Supplier said to use type N cement at a ratio of 3 sand to 1 cement, would this be correct? Spread the mix about 1/4" past wire and then push the stone in back to the wire. Tried with consistency to lay block with and then kept whetting it down, but alas NO luck. Am I on the right track and just not holding my mouth right or have I met my DIY match?
Thanks for any help.
