What adhesive works best to glue paving bricks to concrete?

well you could glue them, but, if you just lay them on the concrete and fill the voids with sand and wet it down with the hose the sand will settle in and they wont move. except maybe the ones on the far outside edgesWhat adhesive works best to glue paving bricks to concrete?

you have to use a motar or cement mix....any type of caulking or liquid nails will dry, crack and come apart with weather changes
There is an adhesive specially made for concrete, can be bought at Home Depot, comes in tubes so application is easy, bricks and concrete must be absolutely clean and dry, run two beads down each brick, near but not on the edge, set in place, use a hammer and a 2 x 4 to set the bricks, several at a time, this is a three person job.
Mortar of course, but you can try Gorilla Glue if you are lazy or if your trying to glue back on a small chip or something.
cement
Mortar (cement, sand and water)
Liquid nails makes an excellent product.Worked great for me.
