How to Lay Pavers Over a Concrete Slab

Dry fit the pavers on the concrete pad by laying the blocks out in the desired pattern across the entire pad. Stretch a chalkline tight across any edges where the blocks overlap the edge of the concrete. Lift and release the chalkline quickly to snap a blue line indicating where cuts need to be made.

Make any cuts necessary with a masonry wet saw that is available for rent from most hardware stores. Install the pavers with the cut blocks against a vertical surface or along a hidden edge, which will be the starting point of the installation.

Mix mortar and water in a bucket to a consistency of peanut butter. Spread the mortar with a notched trowel along the first edge where the cut pavers will be installed. Drag the notched edge of the trowel across the surface of the mortar to create grooves.

Lay out the pavers along the edge of the pad on top of the grooved mortar. Set a level on top after you have laid two or three to check the level. Hammer the top of the pavers lightly with a rubber mallet to level out any high points. Do not leave any gaps between the stones. Continue to lay out pavers around the edge of the pad until you have two edges complete.

Spread dry cement across the surface of the pad beginning in the corner of the two completed edges. Drag the notched trowel across the dry cement to create grooves. Install the pavers beginning in the corner and working outward to the two remaining edges. Level each paver as you go.

Install the remaining edges in the same manner as Steps 3 and 4. Allow the mortar to dry for 24 to 48 hours.

Spread concrete sand over the surface of the patio. Brush the sand into any grooves between the pavers with a broad-head broom. Wet the surface of the pavers with a low-pressure water hose to solidify the concrete sand.
