Pavers over concrete patio?

I want to install pavers on top of my 10x15 concrete patio. Is the bed of sand necessary or can I just glue every paver down along with the perimeter strip?
The concrete it is going on top of is only 2 years old with no defects.

Interesting concept. I would like to do something similar on aggregate concrete patio. Not sure of how this would work.

If you are putting it on top of concrete, don’t think you need a bed of sand. I would use some mortar to adhere to the concrete.

Of you are grouting perimeter bricks, you are creating a bathtub when it rains. So you need to grout all bricks so there is no opportunity for water to get down there.

mortar set the pavers on top of the concrete and mortar all the joints. you need it to be water tight or its going to trap water. (what zappas said)
not sure on aggregate but i'd expect it would be the same. that look would be awful if visible though

I've done it. Glue outside perimeter with landscape adhesive. Use polymeric sand for the joints. The rain draining off the roof will cause you to refresh the polymeric sand every few years where it hits. Much easier than mortar.

I've been researching this myself. I read one article that suggested drilling holes (completely through to the dirt) in the existing concrete to allow for drainage.
Not sure how valid that approach is.

Drainage is certainly a concern. I was not comfortable with the pavers being above the slab lines and above the weep holes so I left a 2 foot gap from the brick for drainage and painted the concrete slab. The patio already had the proper tilt for drainage and is completely exposed with brick on 2 sides.

Don't do that. When water gets under concrete it will heave and/or crack.

Thanks for the replies.
What I am trying to do is raise the entire footprint of my patio to alleviate water pooling in heavy rains.
I installed a channel drain along the front (15ft) but on downpours it doesnt take much to back up.
That feeds into the terrible design of my yard draining down into my heavily sloped patio. I am basically dealing with a "V".
Had one of my very experienced contracting customers come out and inspect for a possible pour-over, but the hardi plank comes down too low to do it at a proper thickness.
I would definitely mortar all joints, I need this thing tight as shite.
So yall say use mortar as the adhesive for all tiles to concrete?
