Install as many pavers as possible without cutting. Follow your layout plan, installing the pavers correctly as close to the paver border as possible.
Lay the paver to be cut in place, allowing it to extend past the curved paver border. Mark the paver with a pencil, outlining the paver border onto the paver. Eyeball the paver as it overlaps the paver border to be sure your pencil mark is correct. You can cut more off if the first cut is not right, but you can not add more to paver, err on the side of caution.
Spray on gloss concrete sealer over the pencil mark to preserve the mark. Do not cover the entire paver unless you intend to seal all the pavers in the installation.
Wear a dust mask and eye goggles before proceeding to cut the paver. The cutting process will produce a large amount of dust and debris, which can damage the eyes and lungs.
Attach a 4-inch diamond tip blade to the right-angle grinder. Pay attention to the direction of the arrow on the blade, making sure that you install the blade facing the right way. Lightly mist the paver with water before cutting to reduce the dust production.
Cut the paver with the right-angle grinder, following the pencil mark made earlier. Cut in small turns to ensure that you follow the curved pencil mark correctly. Cut 1/2-inch at a time and spray the paver with a mist of water.
Cut the paver as deep as the masonry blade will extend. Gently tap the paver with a rubber mallet to break the paver. Place the paver into the curved slot and test the fit. Trim the paver, if necessary.
