Adhering manufactured stone to Concrete
I'm finally in the stage of installing my manufactured stone veneer to the poured concrete foundation wall. The walls are clean. A local mason told me I needed to apply a scratch coat to the wall before applying stone. So I did in one section, but to me it seems like the scratch coat is very brittle. I mixed up some mortar and applied a stone to it and it stuck fairly well, I also applied one to just the concrete wall which stuck good as well. Do I really need to apply a scratch coat? I'm afraid the scratch coat will not adhere well and start coming off, taking the stone with it.
