The One-Step Alternative

NexPatch is an all-purpose fire-resistant finishing compound for filling joints, making repairs, and covering fasteners on interior walls and ceilings. Developed for NexBoard™ fire-resistant composite wall panel installations, NexPatch utilizes proprietary Durazite™ fire retardant technology to ensure the highest level of fire protection carries through to every joint, repair and patch for the fire-rated assembly.

Pre-mixed and ready to use, NexPatch bonds to most surfaces, does not need taping or priming, cures quickly, is sandable and paintable, cleans up easily with water, and is fiber-reinforced to guard against cracking and joint separation. NexPatch has almost no shrinkage and, when cured, is resistant to water absorption and mold development, with low VOCs.

A Multi-Purpose Patching Solution

In addition to its use with NexBoard wall panels, NexPatch may be applied to drywall and other types of interior wallboards, replacing gypsum-based and other finishing compounds as well as a variety of caulk and sealant products. Its adhesion, strength and resistance to moisture and mold also allow NexPatch to be used for exterior projects.

Tested as part of a NexBoard wall assembly, NexPatch has achieved an ASTM E84 Class A Fire Rating and passed the NFPA 286 Corner Room Test with zero smoke and combustion. With its versatility and unrivaled set of properties, NexPatch has the potential to become a universal patching, sealing and finishing solution and strategic differentiator in the building materials industry.
