The Grace Perm-A-barrier NPL 10 5gl has a fluid consistency. This is a single component that forms a strong latex membrane. It is meant to cure construction surfaces by forming a monolithic bond
This is a resilient barrier that forms an elastomeric sheet that provides longevity to the construction surface. Ideally meant for assemblies with fire-rated designs, this barrier is one of the best NFPA 285 compliant wall designs. Opt for it to see durable results on any construction surface. The Grace Perm-A-barrier NPL 10 5gl has an impermeable membrane which does not allow water, moisture, gas, or vapor to contaminate the surface. The protection provided by this barrier is superior without changing the look of the surface. This is a solid barrier that does not allow air infiltration that can have damaging effects on concrete. It also preserves the energy of the structure and acts as a robust plane for water drainage.
