How do low temperatures affect the adhesion of BUR materials?

Low temperatures can negatively impact the adhesion of Built-Up Roofing (BUR) materials. Cold conditions can cause the adhesives and sealants used in these roofing systems to become less viscous and more difficult to spread or bond effectively. In turn, this can lead to incomplete bonding between layers of roofing membrane or between the membrane and the substrate, ultimately compromising the waterproofing integrity of the system.

In addition to the changes in the physical properties of the materials, low temperatures may also affect the curing process of adhesives. If the temperatures are too low, the adhesive may not cure properly, resulting in weak bonds. Maintaining optimal application temperatures is essential for achieving the desired performance and longevity of BUR materials, making awareness of temperature effects crucial for roofing professionals.
