Yes, you absolutely can and should add non-marking feet to your outdoor furniture legs for a stone patio. This simple addition is crucial for protecting your investment. Stone surfaces, while durable, can be scratched and scuffed by the repeated movement of metal or hard plastic furniture legs. Non-marking feet, typically made from soft rubber or thermoplastic rubber (TPR), create a protective barrier. They prevent unsightly marks, reduce grinding noise when moving chairs, and provide better stability on uneven stone. To install them, first clean the furniture legs thoroughly. Measure the leg's diameter to select the correct size of caps or adhesive pads. Most products simply push on or stick securely to the leg's bottom. Choose feet specifically rated for outdoor UV exposure to ensure they don't crack or degrade. This minor upgrade preserves the beauty of your patio and extends the life of your furniture, making your outdoor space more enjoyable and maintenance-free.
