Refinishing Old Marble Surfaces
By Torin Dixon
Victoria called this week to ask about restoring an old marble table top she purchased at a rummage sale. The size was perfect for her kitchen island top. The marble piece had been out in the elements for may years, and the surface was dull, etched, and stained.
Before tackling this kind of project, you need to assess your handyman skills and determine if you are willing to put in the effort to bring a piece like this, back to life. You also need to determine what your expectations are for the finished result. For homeowners, you can get good results on lighter colored marble, if you are willing to settle for a satin finish. For dark colored marble, if you are satisfied with a ‘Honed’ surface look, you can also get good results at home. If you are expecting a mirror like, factory finish, then you will certainly need to call in a professional to get a factory finish.
Once you have determined that you want to handle this type of project I would order two things from StoneCareOnline.org, our HMK R55 Intensive Cleaner, and our P21 Marble Polishing Paste. Additional supplies; Silicon Carbide Wet/Dry Sand paper in grits 120, 220, 320, 400, 600. Sanding Block
Follow These Steps:
- Clean marble surface with R55 solution (1-part to 5-parts water)
- Rinse Well
- Using water, start sanding marble with 120 grit in circular motion. Rinse with water frequently. Sand until entire surface looks the same.
- Repeat process with consecutively finer grits: 220, 320, 400, 600 rinsing well between grits.
- Allow to dry 2-4 hours
- Use P21 Marble Polishing Paste much like a polishing compound. Apply P21 to a folded cotton cloth and polish in circular motions, rubbing into marble surface very vigorously. Polish in a small area (1 square foot or less). Buff off polish with a separate buffing cloth to a uniform finish. You may wish to use a Lambs Wool pad on a buffer.
- Repeat while overlapping areas slightly to insure complete coverage.
- Repeat process until you reach desired shine and finish.
Using this method will save you hundreds of dollars, giving you a beautiful hand rubbed finish on most lighter colored marble surfaces. For the adventurous, you may wish to use our Professional Grade P27 Polishing Powder, although it is recommended for Professional Use only.
