Help with Flagstone Patio?
I want to put down a 500 square foot patio behind my house. I just dug down about eight inches from the base of the house and have it somewhat level. I was planning on putting down four inches of concrete then the flagstone on top. My backyard is pretty sandy dirt, and I have very moderate weather-never snows.
My questions are:
1. Is the four inches of concrete below the flagstone overkill?
2. Should I put sometype of base down on the sand-like some type of road base or grit?
3. Can I just use the premix cement to lay each piece of stone on top?
