BlazeMaster® Caulk & Walk® Pro is specifically designed to be compatible with BlazeMaster CPVC fire sprinkler pipe, and is listed for CPVC pipe penetrant fire-rated assemblies. It has been tested for penetrations through a variety of assemblies, including 1 and 2-hour rated gypsum wallboard and 2-hour concrete walls. Also been tested for metallic pipe penetrations which enables the product to be utilized for firestopping when pipe transitions are employed.
Lubrizol BlazeMaster CPVC fire sprinkler systems have been used successfully for decades in building construction and renovation. BlazeMaster systems are ideally suited for use in fire protection primarily due to their ease of installation, outstanding corrosion resistance, low flame spread and low smoke characteristics. However, these properties can be compromised if the CPVC pipe comes in contact with incompatible chemicals found in some construction products.
One area where these incompatibilities can be found is in firestopping sealants. Certain firestopping sealants within the industry contain chemicals that are incompatible with CPVC piping systems. These chemicals can cause the wall of the CPVC pipe to weaken and may even cause environmental stress fractures. BlazeMaster® Caulk & Walk® Pro is a firestopping sealant that is compatible with BlazeMaster CPVC fire sprinkler pipe.
BlazeMaster® Caulk & Walk® Pro is an intumescent, acrylic-based firestopping sealant for use in fire-rated building construction, that is paintable, and easy to install. View our installation video for step-by-step instructions.
