Often, many repair needs could have been avoided with the use of a masonry sealants. Ideal for several applications ranging from brick to concrete, sealants help protect the building from water penetration, among other things.
In this article, we are looking a bit more into sealant applications and how they can help maintain your building’s structural integrity.
Typical applications requiring sealants
The use of sealants sometimes referred to as caulking, has expanded as façade construction has evolved. With more cladding materials available than ever before, more pathways have opened. Below is a generalized look at a few of the most common applications that require sealing:
- Joints between stone veneer, concrete, and metal cladding panels
- Stone to flashing points, masonry expansion, and coping joints
- Window and door perimeter joints
- Glass and glazing perimeter joints
- Joints in horizontal surfaces such as plazas and terraces
While the majority of the referenced joints are simple butt joints, special joints developed for new applications may include:
- Fillet joints
- Lap joints
- Glazing beads
- Glazing heel beads
The purpose of sealer in joints
As mentioned, there are several beneficial reasons to apply a sealant. In general, a masonry sealer helps to prevent or reduce water absorption. With the reduction of water, the following concerns are also eliminated:
- Mold and mildew growth
- Structural deterioration
- Structural surface staining
- Reduction in spalling and surface cracking
Today, most high-performance sealants include silicone or polyurethane bases. These products have replaced older options that include polysulfide and acrylic, butyl, and drying oil-based compounds. However, choosing the best sealant for the application at hand depends upon the substrate, movement requirements, and overall aesthetics.
