Repairing Faux Marble Repairing Faux Marble
Faux marble made of stone or plastic can become cracked or damaged. Using the appropriate techniques, you can repair small problems with a faux marble piece. Follow these tips to restore your faux marble to its original elegant look.
Remove the Piece
Start by removing the entire faux marble piece, such as the sink and countertop. Make sure to remove all additional hardware attached to the piece. This step may not be necessary if you are sealing or filling cracks, but you will have to crawl under under the sink or counter to fix the piece.
Clean the Faux Marble
Use a dewaxer and a degreaser to clean the surface area. Use rubbing alcohol to finish the cleaning. Make sure the entire surface area is dry before proceeding to the next step.
Carefully sand your faux marble piece so not to leave scratches in the paint that cannot be hidden. You can prepare the surface using an “SOS” pad where the soap can cut through any oily residue while the steel wool of the pad can lightly buff the surface area. You shouldn’t need to use any power sanding equipment to prepare your faux marble for repainting. Allow enough time before proceeding to paint.
One possible repair is to paint the faux marble. This technique can cover small cracks. Obtain a good two-part epoxy paint designed for sinks and tubs. You can get this paint in blendable colors or in muted beige, eggshell and white.
Use only a brand new, high quality nylon-polyester brush. Remove any loose bristles and discard when you are done with the job. Solvents in the epoxy paint you are using may have an adverse reaction to any old latex residue or old oil-based paint resin, possibly reactivating these and having an effect upon your new paint application. Always mix the epoxy paint according to directions letting it steep for at least an hour. Apply it in a thick even coat working a swirled pattern to compliment your existing faux marble design. Do not worry about leveling brush marks because these will disappear with drying. Take your time. Allow it to cure for five days before reinstalling.
Another option for repairing faux marble is to use a sealing agent. For leaks around drain holes or stress cracks in the surface, try a silicone product such as Goop. Avoid latex products that crack as they age.
After cleaning, get underneath the surface of the faux marble. Work the sealing agent deep into the cracks, using a toothpick as necessary. Work in layers, rather than filling cracks up all at once.
Extend the sealing agent at least ½ inch on either side of the crack, and be sure it is completely sealed to the surface. Allow it to cure at least overnight. If you use it too quickly, you’ll have to repeat the repair.
Grout for Faux Marble
Many pieces of faux marble are plastic imitations, such as you would find in sinks and countertops. There are also stones that are painted and finished to have the appearance of marble, creating a stone faux marble.
If you have this type of a faux marble surface, then you can use a thinset or a grout to repair the stones and reset them.
