Weatherproofing

Weatherproofing has been one of the most common applications for ImmerSeal® over the past 20+ years.  ImmerSeal® is frequently used to seal over existing failed wet sealant joints on a variety of substrates.  A small bead of ImmerBond® adhesive sealant attaches each side of the ImmerSeal® to the healthy substrate, resulting in an aesthetically pleasing, economical and long lasting sealing solution.

The same is true in new applications. Do it right the first time!

Failed wet applied joint sealant, leaky skylights, leaky window systems (See Figure 1), flashing leaks, leaky roof joint & penetrations and under-sized expansion joints are all frustrating weatherproofing problems. Fortunately, for these and other problems, ImmerSeal® pre-cured sealant is a permanent repair option. The unique properties of ImmerSeal® make it ideally suited for a variety of applications where other materials have failed time and time again. When properly applied, ImmerSeal® provides an economical, attractive, and permanently watertight sealing solution.

When using ImmerSeal® in repair applications where an existing sealant has failed, there is no need to cut out the failed sealant or grind the surface of the substrate to completely remove the old sealant. ImmerSeal® can be simply applied over the failed joint, crack, or leak. This approach is especially effective when working with soft or sensitive substrates such as EIFS because grinding and removal of the failed sealant can cause costly damage to the substrate. Because the old sealant does not need to be removed, the total time and cost associated with the repair can be dramatically reduced. ImmerSeal® is readily available in many standard sizes, colors and finishes to fit the needs of most any project.

Because pre-cured sealants like ImmerSeal® have been successfully used to repair failed sealants for many years, and are rapidly becoming accepted by the industry as a viable alternative to cutting out failed sealant, more and more contractors, architects, consultants and specifiers are taking a closer look at the benefits of using pre-cured sealants. Though they are not the answer to every sealing problem, they can also be used in new construction applications. As pre-cured sealants become more established in the construction industry, it is expected that changes in basic joint design will occur to take advantage of their benefits in new construction.

Examples of Possible Joint Designs

Example 1: Simple bridge type joint design with prefabricated recesses in the substrates for flush installation of ImmerSeal®.

Possible Joint Examples

Example 2: Architectural joint design in concave configuration for a better appearance in expansion joint details.

Possible Joint Examples

Example 3: Architectural joint design in concave configuration with prefabricated recesses in the substrates for “snap in” flush installation of ImmerSeal®.

Possible Joint Examples

Example 4: "U" Joint design can be used in a standard joint configuration and results in a joint that looks as good as or better than a tooled wet sealant joint.

Possible Joint Examples

Finally, we can almost certainly conclude that pre-cured silicone sealants are here to stay. Though it is not likely they will replace all other sealing systems, their share of the market will continue to grow. The scope and magnitude of their use in the construction industry will greatly depend upon the collaboration between contractors, specifiers, architects, consultants and the manufacturers.
