I am interested in purchasing a house, but I don't like the outside mortar because it protrudes a lot and is very uneven. I think the mortar would be referred to as very thick extruded joints. My realtor called it cake batter mortar but am finding no online hits for this. At any rate, does anyone know what it might be called and if it possible to remove the excess mortar? I would eventually want it as flush or concave as it could get, but any improvement would help. Can this be chiseled or sanded down? Thank you!
