The service life depends on movement, cleaning, moisture, product quality, and installation. Countertop-to-wall joints, sink rims, backsplashes, and plumbing penetrations should be inspected regularly. Old caulk must be removed and the area cleaned and dried before new material is applied. The sealant should be compatible with stone, quartz, tile, metal, and other adjoining materials.
Key considerations
- water resistance
- mold resistance
- movement accommodation
- flexible sealant
- replaceable joint
- color-matched options
