        "text": "For optimal adhesion and a lasting seal, it is generally recommended to remove old caulk before applying new. Applying new caulk over old, cracked, or deteriorated caulk can lead to poor adhesion of the new material, resulting in premature failure and an ineffective seal. A clean, dry, and properly prepared surface ensures the new caulk forms a strong, durable bond. In some cases, if the existing caulk is in excellent condition and the new caulk is compatible, a thin bead can be applied, but this is less common for exterior siding.",
