How to Use a Polishing Stone to Smooth Granite Edges

Once your new granite countertop is installed, you might locate rough edges left by the installers. While you can smooth rough edges in tiny areas with a handheld polishing rocks, for bigger and labor-intensive projects you’ll need a grinder or polisher available at most home rental lawns, hardware and home improvement stores. You will want the tool equipped with diamond-grit pads.

Hold the flat edge of the polishing rocks in a 45-degree angle, then rubbing the rough place throughout the border of the granite. Rub the stone in 1 direction throughout the granite border, since you can usually maintain the angle much better this way compared with rubbing back and forth.

Switch to your 25-degree angle when you’re planning to smooth out the rough edges by making them marginally around.

Alter the angle between these two degrees until you have the border and smoothness on the granite which you want.

Replace the polishing rocks using a resin-bonded polishing stone to finish smoothing the granite. The resin-bonded stone suppliers a finer grit than that provided by a standard polishing stone. It is comparable to switching from a rough-grit to your finer-grit sandpaper.

Keep polishing the granite border using the resin-bonded stone, alternating between the 25- and also 45-degree angles before the granite is smooth.

Apply a buffing chemical intended for granite to bring a last sheen to the surface. Wipe it on using a soft rag. When it dries, buff until the chemical disappears.
