I've built an enclosed front porch, about 4m2 including 1m2 of original porch recessed in front of the old front door.
Before laying some Indian sandstone that I have lying about, on my new concrete floor, I need to raise the level of said floor by about an inch and a half. Am I OK just bunging in a very sloppy mix of sharp sand and cement, then laying the stone once it's set, or should I mix something stronger?
Cheers Richard
