Empty a bag of silica sand into a small rental mortar mixer (about $45 per day). Add the two-part EcoSystems grout, then add the recommended amount of water. Mix for three minutes. Wet the stones with a light hand sprayer. Empty the mixed grout onto the stones and squeegee the sand and epoxy grout mixture around to cover the joints between the stones.
Builder's Tip: On a hot day, the stones will warm up and the water spray will evaporate. Keep spraying as needed prior to application of grout.
The sanded grout joints will set up by themselves. No pressure is needed to compress the sanded joints.
Use a push broom to sweep the excess grout from atop the stones. Sweep the stone-covered area clean. Allow the grout to set for 48 hours prior to placing heavy objects on the stones.
