 Nuco

 Nuco makes the NuFlex line of sealants and adhesives and the Self-Seal line of firestop sealants. From everyday kitchen-and-bath silicone and painter’s caulk to self-leveling joint sealants, hybrid sealants and heavy-duty construction adhesives, there’s a NuFlex product for nearly every job, inside or out. They’re built to seal tight, bond strong and hold up through Canadian winters, summer UV and everything in between.

We stock the line here at The Caulking Store, so you can get pro-grade product and real advice from people who talk caulk all day.
