Moisture trapped between the old sidewalk and the new pavers can cause them to weaken.
Brick pavers over concrete sidewalk.
Use liquid nails or another suitable adhesive to make sure that they stick.
For instance if you put pavers over a concrete patio the height of the patio will be increased by the height of the brick.
Allow the adhesive to dry before you do anything else around the pavers.
This is how to lay the thin pavers over concrete.
The other advantage for us is that we already had monkey grass along the borders of our sidewalk.
You will notice one difference however between a mortared path and a mortared patio.
Which also helped in creating a barrier and a visual step up over to get to the sidewalk.
This outside layer will provide a level of stability for the entire project.

This is how to lay the thin pavers over concrete.
Lay out a row of bricks along the concrete surface to determine your pattern.
They offer the same potential for a varied handsome surface only on a smaller scale.
Leave a 1 2 inch gap between the bricks.
Second the height of the installation will obviously be higher than it was.
You can create a variety of patterns with brick pavers.
