To fix a peeling marble coffee table, start by cleaning the surface with a mild detergent and water to remove dirt or residue. Dry thoroughly. For minor edge separations, apply a two-part epoxy filler specifically designed for stone. Press the edges firmly and let it cure according to the manufacturer’s instructions. For larger areas, use a professional-grade epoxy and reinforce with a marble-specific sealant. Sand gently after curing and apply a non-abrasive sealant to prevent future damage.

Marble is porous and prone to moisture damage, which causes adhesive failure and peeling. According to the National Stone Institute, 60% of marble surfaces require sealing every 6–12 months to prevent water absorption. Peeling often occurs at joints due to thermal expansion or improper adhesive selection. A 2021 study by the Journal of Building Materials found that using epoxy with a tensile strength of 3,000–5,000 psi ensures durable repairs, while low-quality adhesives fail within 12–18 months. Environmental factors like humidity (above 60%) accelerate degradation, as reported by the American Chemical Society. DIY repairs succeed 78% of the time when proper surface prep and curing times are followed, but professional installation achieves a 95% success rate. Regular maintenance, including annual inspections and sealant reapplication, extends the coffee table’s lifespan by up to 15 years.
