Durability of Elastomeric Sealants

File Opener

Sealant is used in the exterior joints of every modern building, but usually incorrectly. Owners have high expectations for performance and durability, but premature sealant failure is common, resulting in air and water infiltration, property damage, and expensive repair work. Design details and installation practices contribute to the service life, but there is a bigger problem in the industry—many sealant products cannot resist movement and weathering, which are their core functions.

When there is a tile or stone failure, a contributing factor is often the lack of properly installed movement joints. Just like concrete sidewalks and bridges, tile and stone need to have movement joints to control the anticipated movements within a structure. Tile and stone will expand and contract when it is subjected to heat/cold or moisture/dryness. It is critical for architects to properly specify the design, materials, and layouts of movement joints.

Silicone’s excellent aging characteristics, resistance to ultraviolet (UV) light and weathering, and long effective life span has made pre-cured sealants a popular material for construction-related applications.

Pre-cured sealants of silicone are produced by extruding elastomeric sealant material and allowing it to cure to a rubbery, flexible product in a controlled manufacturing environment. They are packaged in cured form—often in rolls—instead of typical liquid form packaging such as tubes or pails. The sealant …
