am going to install 350 sq ft of 1.5 inch sawn cut bluestone over roof covered patio in freeze thaw area. Bluestone is of two sizes 18 in x 24 in and 12 in x 18 in. Concrete patio is without cracks and is fairly level with little straight edge deflection. Was considering using 3/4 inch noch trowel to spread heavy bed thinset and to backbutter the stone and set. Then I would point up the joints with a dry mortar.
I had consideredputting down either schluter Ditra or a Blanke membrane prior to stone. Is this necessary?
What is cleanest way to strike off the joints?
Any ideas would be appreciated.
