How to Finish Flagstone Edges

Updated February 21, 2017

A flagstone patio imbues a home landscape with a rustic appearance. Like rough-hewn slate, flagstone’s natural appearance makes it stand out from its traditional brick and paver cousins. Flagstone is easy to install on a gravel bed with sand used to fill the joints. Flagstone edges are typically kept raw, but should be finished with metal paver edging. Metal paver edging is placed around the perimeter of the patio to help secure the outer stones in place. Install paver edging once the entire patio is in place.

Start at a corner. While holding the paver edging firmly against the outer edge of the flagstones, stick the spike in the hole, and use a mallet to hammer it into the ground. Hammer the spikes in at angles.

Continue to move around the patio, holding the edging securely in place while hammering in each spike.

Cut the edging with tin snips once you get to the next corner.

Backfill around the metal edging with soil. Smooth the soil over the top lip of the edging to hide it.


If you do want a raw edge on your patio, install flagstone edging around the perimeter. Flagstone edging is a much narrower stone that will create a nice border. Install the flagstone edging the same way you installed the flagstones, then secure the outer edge of the flagstone edging with metal paver edging.
