I have three concrete steps leading up to my porch. I want to lay a 2" thick limestone or leuders slab on each step. What material should I use to adhere the slab to the concrete?

2" thick limestone should be pretty solid on its own. I'd think liquid nails or any construction adhesive for masonry would work.

I'd recommend just mortaring them down with a 5/8 joint to the concrete. Make sure you clean both the stone and substrate prior to installation.
