How to Repair Scratches in a Marble Table Top How to Repair Scratches in a Marble Table Top

A marble tabletop can be an elegant, classy addition to any home and will most likely outlast any other furniture in your home because of its sturdiness and durability. Marble is also timeless in that it will never be outdated or old fashioned. Unfortunately, even with its attractive characteristics, marble is very vulnerable to becoming scratched or etched because it is fairly soft and can easily be scratched.

You should expect that your tabletop will incur some scratches from time to time. But small scratches can usually be repaired, especially if they are not large or deep. Follow the information below to prevent scratches and repair them. Use them as your repair guide. It’s important for you to understand that these suggestions are intended for repairing authentic marble, not for artificial marble.

What you'll need:

  • Soft, clean cloths
  • Sponge
  • Fine sandpaper, or
  • Steel wool
  • Marble polish, or tin dioxide

Step 1 – Prevent Scratches

Preventing scratches on your tabletop should be your top objective and first plan of action. There are several preventative steps you can take to avoid having to repair scratches. First, always use coasters, placemats, or tablecloths to place your drinking glasses on when using your marble tabletop for dining. If you have decorative items on the tabletop, be sure they are protected on the bottom with felt or other protective cover, so that the item does not scratch or mar your tabletop surface. Never use the tabletop for craft projects. Never allow children to play on the tabletop.

Step 2 – Cleaning Your Marble Top

To clean a marble tabletop, simply use a damp cloth or sponge, and gently wipe it across the table surface. Then dry it with a soft, dry cloth until the marble surface begins to shine. Avoid using abrasive cleansers on your marble tabletop, as they will scratch it.

Step 3 – Repairing a Scratch

If you do discover a scratch on your tabletop, follow the directions  below.

a. Use fine grain sandpaper, and gently sand the scratch. When the scratch has been removed with the sanding, use a commercial marble polish to polish the surface where the scratch had been made. For best use of your marble polish, follow the manufacturer’s instructions that you will find on the product label. Look for a commercial marble polish at a local home improvement store.   

b. It is sometimes possible to repair a scratch and buff it by using steel wool. But be sure the steel wool is very fine (#000). Be careful that you buff the marble surface lightly, using small, gentle strokes.

c. Another method that often works well is to use a polishing powder, or tin dioxide. This can be purchased from your local monument company that sells grave markers. Or, if you have a marble dealer in your area, you should be able to purchase this product from him.

Step 4 – Repairing Hard-to-Remove Scratches

If the scratch you have is too deep to be removed without further damaging your table top, you will need to have a professional repair it for you.
