Not sure if everyone wants to learn along with us but… it is our blog. =) What we have learned is that whenever cement is used in a mortar mix, it makes it impossible to carry water away from the stone. If cement mortar is used over lime mortar (which was used exclusively when the Mooreland House was built) it traps the water and the lime dissolves out of the mortar leaving only sand that washes away. The old school techniques have come back into vogue and it is just at the right time. We are going to be able to use all the “new found” old techniques and make Mooreland House Great Again!
