I have two small areas at the base of my foundation I would like to repack with mortar. I don't fully understand the properties of mortar. Living in New England where the summers get really hot and the winters get really cold, would the fall or spring be the best time to pack it?
My mind is stuck on the drying process and whether or not the mortar will expand or contract. Or will the mortar always dry in the same shape it was applied?
