With the gravel base compacted, install galvanized steel edging around the perimeter of the base (images 1 and 2). This edging marks the outside of the 11-foot square to be filled by the pavers. Edging is also available in plastic or aluminum.
The final base material is a one-inch layer of sand.
Spread the sand over the gravel base to a depth of one inch. Screed the sand with a 2x4 using a pair of 1-inch PVC pipe and a depth guide (image 3). You can create similar guides by sawing wood into long, 1-inch thick strips. Then remove the guides and fill in the remaining sand.
With a firm, flat base prepared, you're ready for the pavers. Start in the corner, setting each paver into the sand by tapping it lightly with a rubber mallet (image 1).
Using the set pavers as stepping stones. Fill in a small area then check with a level to make sure they are even. Remember, you want a slight slope for drainage. Make adjustments with the rubber mallet (image 2).
If a paver is too low, remove it, add sand and reset. Following the pattern you dry laid earlier, it won't take much time to finish setting the pavers.
Now that the pavers are set in the base, use a push broom to fill in the joints with a fine layer of sand (image 1). Sweep off the excess sand from the patio surface.
To pack the sand into the joints, spray the patio with water from a garden hose (image 2).
When the patio has dried completely you may need to fill in certain joints with more sand.
