I have a solid concrete stoop 7 ft x 10 ft. I want to put 12in. wide x 2 in. thick bluestone as a border. Then I want to fill in with 2 in thick concrete pavers on the concrete slab in a basket weave pattern flush with no mortar joints. Do I put down a dry mortar mix (3 to 1) and then lay the pavers down and wet it when I am done laying them?
