Cultered Stone/Scratch Coat Question

[fishlips]

I am putting up cultered stone on the cabin and never seem to have enough time to finish an area. Does anyone know how long the scratch coat can remain exposed to the elements before it loses its bonding properties or starts to degrade? I want to focus on getting the scratch coat done first, then go back a couple weeks later to hang the stone.

You can wait a very long time. It wont loose its bonding properties.
