3M™ Permeable Liquid Flashing Membrane 3015LF is a paintable, rollable, or sprayable commercial grade polyether-based vapor permeable liquid flashing designed for detailing windows and other building fenestrations. Combining 3M Permeable Liquid Flashing Membrane 3015LF with 3M™ Vapor Permeable Air Barrier 3015VP as a wall membrane creates a vapor permeable building system.
Performs Well in a Wide Range of Situations
3M™ Permeable Liquid Flashing Membrane 3015LF is a single-component, Silyl Terminated Polyether (STPE) based liquid flashing system. It is designed for detailing windows, doors, pipe penetrations and other building fenestrations and can be rolled or sprayed on vertical, horizontal or overhead surfaces. It has a VOC content of less than 100 grams/liter, dries quickly and adheres to damp surfaces.
This product performs well in both cold temperatures and high heat and humidity and can be applied from 25° to 100°F (-4° to 38°C), with a service temperature range of -40° to 240°F (-40° to 116°C). The final cured product is paintable and compatible with many building sealants, including synthetic rubber, butyl, polyurethane, silicone and silane terminated hybrid sealants. It demonstrates excellent adhesion to concrete, steel, exterior gypsum sheathing and wood without the use of any primer. The vapor permeable attributes of this product help create a vapor permeable wall system when used with a vapor permeable wall membrane.
