Sealant Applications

Sealant being applied to brick joints.
The use of sealants (caulking) has expanded as facade construction has evolved and new cladding materials have become available.


What Are The Typical Applications Requiring Sealants?

  • Joints between stone veneer, concrete, or metal cladding panels
  • Stone to flashing points, masonry expansion, and coping joints
  • Joints at window and door perimeters, and glass and glazing perimeters
  • Joints in horizontal surfaces such as plazas and terraces


While the majority of joints are simple butt joints, specials joints developed for new applications include fillet joints, lap joints, glazing beads, and glazing heel beads.


Most high performance sealants used today are silicone or polyurethane-based. These high performance products are now replacing older products that contain polysulfide and acrylic, butyl-, or even drying oil-based compounds.


Selection of sealant type depends upon the substrate, movement requirements, and aesthetics.
