EZ-4719

BRUSH GRADE DUCT SEALANT


EZ-4719 is a Underwriters Labs listed sealant for heating and air conditioning ducts. It is formulated with a lower viscosity than most other sealants making it especially well suited for brush application. It is a flammable solvent based product. EZ-4719 is reddish brown in color like our EZ-6010 which offers similar qualities but at a higher viscosity well suited to knife or trowel application.
