Belzona Facts:

It was necessary to protect the new insulation with a coating impermeable to water but with a certain water vapor permeability to allow any moisture to escape the insulation. The protective coating had to be impact resistant, have no VOC (volatile organic content), and be fire resistant. Belzona® 3211 meets all requirements.
