how do i lay brick pavers on a concrete surface?
Answers:
I am a brick contractor here in Kansas city. First I would recommend a small area less than 10 x 10 in mortar joints. If you have a concrete slab you will want to get thin set. it is water proof. and a nocthed trowel, you just spread the mortar with that trowel and lay the bricks in any pattern you want. Then come back with regular mortar and make it soupy and poor it on the bricks and pull it to the joint with a grout float. after a small section is finished wipe up with clean water and a sponge. Keep cleaning until the bricks are clean, this may take several attempts with clean water and a sponge. ( I would recommend wearing rubber gloves ) your hand will be very dry for several days if you don't were them. Your skin will crack. then wait few days and acid wash the bricks.
if the area is larger set them in sand, it is easyer for the ground to move and break, if you set them in sand it is easyer to replace them. use a polymeric sand to fill in the joints, it will hold the bricks together like concreat.

you need to lay them in a bed of mortar.leave a 1/4 in. space between each paver.if they are set in mortar,then you will have to mortar between them with a pointing tool,or the back of a teasspoon will work,so as no water can get down to the base and lift any pavers.you may have to use more cement in certain areas to get the proper pitch.look for the pavers to have a crown towards the middle for water drain off.good luck

Fairly easy to do if the concrete is in good condition
You can (and should) lay them directly on the concrete where possible. Use quarry dust (ground up pebbles) or sand to level off any uneven areas before laying the brick. I laid brick directly on top of an older cement sidewalk leading to my house and it worked out great. By the way....... in response to one of the other answerer's suggestions......... DO NOT use mortar. That's ridiculous. That person is an idiot. Just lay them down nice and tight against each other after you've leveled everything. Use some sort of a border (plastic, metal, 4 x 4s, long edging bricks, or whatever) to help keep everything in place.
Our front porch is concrete with a layer of pavers in a basket weave pattern with a soldier course around the edges. They are set in a bed of mortar with mortar between the joints. They have been in place for almost 11 years with no problems.
Our concrete was new. If yours is older, you may need to acid etch the surface to help the motar bond.
