Aluminum gutter leak repair using Parbond penetrating sealant by Parr

Parbond is a synthetic rubber penetrating sealant designed for sealing small joints or gaps between metal, glass, masonry and wood.


Parbond is resistant to sunlight and temperature variations. It will seal small joints and cracks up to 1/4″, and still remain flexible. It is versatile, has moderate elongation or compression and dries quickly. Parbond provides weather protection and moisture resistance at various temperatures through evaporation of solvent to temperature extremes of -20°F to 180°F, water, water vapor and air pressure.
Parbond can be used within the opening or as a surface coating over very fine cracks. Typical applications are: miter joints in window or door frames, needle glazing, top dressing over non-dry sealants to avoid dirt pick up. It can be a sealant for rain gutters and downspouts, around automotive windshields and back lights, and for sealing of sinks, tile and ducts in kitchens, galleys, and bathrooms.
