Setting Walkway BorderAll of the stone mats creating the design have been laid on the walkway. Now it's time to create the border.
We used single porphyry stones for the border. The stones are about four-inches thick, so allow 4-1/4 inches for the border on both sides of the walkway. You'll want to allow room for a joint. Snap a chalk line on both sides of the walkway to mark a straight line for your cuts.
Tip: It is a good idea to spray clear marking coat on the chalk line so it doesn't fade while you are cutting.
Cutting Walkway Stones
Once you have your chalk line, use the wet saw to score a line through your porphyry stone (figure M). Now that your stones are cut, use snips to cut the mat, then separate the stones.
Use your four-foot level as a guide and set single porphyry stones to create your walkway border.
Berm And CompactYou have set your walkway and border, to prevent the stones from shifting lay a wedge of concrete, known as a berm, along the each side of the walkway. Allow the concrete to dry then use your compacter to even out the stones.
Grouting
Dean and Derek used quick setting Eurogrout for the joints in this project. Eurogrout is a quick mix grout alternative to polymeric sand. To mix Eurogrout rent a small mixer, pour a 50-pound bag of sand into the mixer, then add the two bottles of adhesive, and an equal amount of water. Once the product is mixed pour the Eurogrout and squeegee it into your joints. One of the benefits of working with Eurogrout is that it won't stain your stone. Let the grout dry for about 15 minutes then sweep off the excess and voila, you're done.
