Polishing Process of Granite Edges
Sep 29 , 2021

Granite countertops are popular nowadays and can be found installed in many homes. Polishing granite edges won’t be difficult to do on your own. With the right equipment and preparation, your granite edges will be polished easier and sooner.

Before you start on this project, you should first acquire the following materials:

Diamond polishing pads set, Velcro backing pad adapter, Variable speed polisher

Make sure to get a complete set of diamond polishing pads starting at 50, 100, 200, 400, 800, 1500 and 3000 grits. This way you will attain an excellent granite finishing. Also, make sure to get the proper safety equipment.

1. Place the granite on a flat work surface

Set the granite slab down on a level surface like a work table. The granite edges should be hanging off the end of your work table so you can polish them easily. Then wet the edge with water because this will minimize the development of dust particles.

2. Attach the polishing pads to the granite

Attach the backing pads to the grinder’s arbor rotating clockwise. Make sure to tighten it so it is not loose when you are polishing the granite. The first grit pad you should attach is 50 since it is the coarsest pad you can use. Run the grinder at a low speed and start the polishing work.

3. Move the grinder from left to right

Shift the grinder in constant, horizontal motions in quick strokes. Keep the grinder around a 45-degree angle as you work to the edge’s topmost corner. Begin polishing the rest of the granite edge by moving the angle grinder downward using the same left to the right motion used initially. Apply consistent pressure as you move to the bottom corner of the granite’s edge.

4. Continue the polishing process of switching grit pads

Once you are satisfied with the results using the 50 grit pad, it is time to replace it with a 100 grit. Continue the same process as before. The grit 100 will make your granite smoother. The higher the number of the pad, the finer the grit. The next grit pad to use after 100 is 200 then from 200 to 400. Once you reach grit 400, the surface should look very smooth but it won’t have any shine. From grit 400, switch to grit 800. At this stage, you would see the slight shine on granite.

5. Continue to polish with finer grit pads

After polishing with grit 800, change to use grit pad 1500 then to 3000. When working with a finer grit, use a powerful water source to spray onto the edge of the granite for a smoother and more polished look. When polishing the granite edge, move your angle grinder in vertical motions as you continue to go from left to right. At this point, the granite has been smoothed out and you will see a shift from low gloss to a high gloss on the granite edge at the end of this stage. You can spend as much time as you want working with the finer grit pads until you achieve the level of shine that you want.

Don’t forget to coat your granite with a sealer after you are done with polishing for a layer of protection. This will slow the rate at which stains can ruin the surface.
