Caulk often is used to prevent water from going into joints
between:
• Tub and walls
• Tub and floors
• Countertop and back splash
• Countertop and tiled wall
• Sink and countertop
• Toilet bowl and floor
• Corners in shower cabin
Since caulk is flexible, it is right choice for surfaces that
tend to move or shift slightly.
Improper caulking can lead to leaking, wetting, staining, mold
development, moisture smell and water damage.
There is one primary reason to re-caulk it is to change old
discolored and molded caulk. Also, re-caulking or calking can protect
from absorbing water in places like under the walls and the floors where
mold can grow.
The cost of caulking or re-caulking much less than tile replacement
or water damage repair and often only re-calking bring back to old shower
a new and fresh look.
