CAULK
FAILURE
Loss of caulk's initial
adhesion and flexibility, causing it to crack and/or pull away from the surfaces
to which it it applied. POSSIBLE
CAUSES:
- 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).
SOLUTION:
- 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.
