Irion-America, LLC recently introduced its new eXcePt series product line featuring “drip control” caulking and sausage guns to the North American marketplace.

Dave Dunn's December 2017 column.

A caulking sealant has three basic functions: filling a gap between two or more substrates; forming a barrier through the physical properties of the sealant itself and by adhesion to the substrate; and maintaining sealing properties for the expected lifetime, service conditions, and environments.

Longtime readers of this column may note that I have always been a fan of silicone sealants; however, I worked for a manufacturer of these materials for many years, so I hope I can be totally objective. I have no doubt that the durability and longevity of silicones cannot be exceeded in most applications. However, I can offer you several observations from my personal experience using them at home.
