Loss of caulk's initial adhesion and flexibility, causing it to crack and/or pull away from the surfaces to which it it applied.
- Use of lower quality caulk.
- Use of wrong type of caulk for a particular application (e.g., using latex or vinyl caulk in areas where there is prolonged contact with water or considerable movement of the caulked surfaces).
Use a top quality water-based all-acrylic or siliconized acrylic caulk if prolonged contact with water is not anticipated. These caulks are flexible enough to adapt to minor fluctuations in the substrate, stretching in gaps that widen slightly over time. They also adhere to a wide range of interior building materials, including wood, ceramic tile, concrete, glass, plaster, bare aluminum, brick and plastic. Note: Silicone caulk should not be painted.
