| Rapid-curing liquid roofing mastic  Garland introduced a new single-component liquid-applied mastic that is durable and easy to apply. The Tuff-Flash liquid flashing system provides superior water protection and weathering capabilities. It is an asphalt polyurethane that adheres to asphaltic membranes as well as a variety of metal surfaces. This includes SBS, APP, and smooth or mineral surfaced asphalt roofs. It is well suited for complex or irregular roofing details that would present a problem for traditional flashing. The Tuff-Flash system requires no mixing, and can be installed with a brush or trowel.Tuff-Flash liquid flashing is environmentally friendly, having zero VOCs and low odor. It is durable, reflective, and UV resistant (when surfaced). It eliminates the need for a torch or hot kettle, and is easier to work with than two-part products that require exact mixing and have short pot lives. The Tuff-Flash system capitalizes on the benefits of both asphalt and urethane chemistries, and actually builds strength over time as it cures. According to Garland product manager, Tom Stuewe, "This product is ideal for sealing difficult flashing details like an I-Beam or angle iron coming through the roof. It skins over quickly in hours and completely cures in 10 to 15 days, which helps reduce project disruptions and duration. A reflective coating can then be applied within 15 to 30 days." Tuff-Flash liquid flashing can be successfully layered with Garland's Grip Polyester fabric, to add tensile strength and asphalt waterproofing. To prepare modified surfaces for the liquid flashing, gaps in modified surfaces should be sealed with Garland's Green-Lock Structural Adhesive. write your comments about the article :: © 2012 Construction News :: home page |
