Question regarding Scratch Coat. How long should this be left to dry/cure before the second coat/final coat be applied. I have been told it should be about a week ( in this weather should it be less ). I had a plasterer come over to view a south facing wall to the front elevation of my house that needs pebble dashing. He said that he would come the next day after the applying the scratch coat to give it a second coat and apply the stones. Now in this weather I am worried that the scratch coat will dry too quickly and crack. Surely keeping it damp with a fine mist whilst it dry's completely would be the best plan of action and then apply second coat. Any advice would be great. Thanks
