Marble is often chosen for its aesthetic value. The subtle colors and unique vein patterns of this natural stone can add elegance and style to any room or object. Marble is commonly used for columns, vases, fireplace mantels, tile flooring, tabletops and countertops. It is more often used for bathroom countertops and tile flooring than kitchen applications, due to its sensitivity to acidic foods and beverages such as lemon, wine, ketchup and vinegar. Marble is softer than other natural stones such as granite, and is prone to chipping and cracking under heavy use.
Repairing Chipped Marble When You Have the Chipped Piece
Locate the chipped piece of marble, and place it in an accessible area.
Mark off the section of marble to be repaired. Make a square of masking tape around the chipped area. Don't worry if the edges of each piece of tape extend beyond the square.
Clean the area with a non-abrasive cleaner such as pure acetone, and then dry it with a clean chamois or microfiber cloth. This will remove any foreign material and prepare the area for bonding.
Apply epoxy glue or marble repair cement to a small brush. Brush the bonding material on the bottom and edges of the chipped piece of marble and the chipped area of the marble object. Press the chipped piece into the hole and hold firmly for the amount of time recommended by the adhesive manufacturer. Wipe away any excess adhesive before it has time to dry.
Repairing Chipped Marble When You No Longer Have the Missing Piece
Purchase marble dust that is similar in color to the object that you are planning to repair.
Mark off the chipped section of the marble with a masking tape square. Clean the marble with a non-abrasive cleaner and dry it thoroughly.
Use a plastic putty knife to mix a small amount of polyester resin cement with the marble dust to create a bonding agent. The mixture should have a paste-like consistency.
Draw some of the paste into a syringe, and inject it into the chipped area. Allow to dry overnight.
Sand the area with 400- to 600-grit fine sandpaper in order to smooth the surface.
