Saber c\u00f3mo instalar correctamente una membrana l\u00edquida para juntas marca la diferencia entre una envolvente de edificio que se mantiene seca durante d\u00e9cadas y una que falla en el primer vano que encuentra. El sellado aplicado en l\u00edquido se ha convertido en el est\u00e1ndar profesional en la construcci\u00f3n comercial y residencial porque hace algo que las cintas y l\u00e1minas tradicionales f\u00edsicamente no pueden hacer: fluye hacia cada rinc\u00f3n, espacio y orificio de fijaci\u00f3n, y se cura hasta convertirse en una sola membrana continua sin juntas que puedan fallar.<\/p>\n\n\n\n
El proceso de solicitud es sencillo una vez que comprende lo que hace el producto y por qu\u00e9 importa cada paso. Esta gu\u00eda cubre la secuencia completa de instalaci\u00f3n para vanos preliminares alrededor de ventanas y puertas, penetraciones en paredes y aplicaciones de barreras resistivas al clima en paredes amplias. Tambi\u00e9n cubre los errores de instalaci\u00f3n m\u00e1s comunes que causan devoluciones de llamadas y c\u00f3mo evitarlos.<\/p>\n\n\n\n
El producto al que se hace referencia en toda esta gu\u00eda es Tower Sealants AU-1 LAB (Barrera Aplicada L\u00edquida). Es una barrera l\u00edquida elastom\u00e9rica de SBR de un solo componente que funciona tanto como membrana de sellado l\u00edquido como barrera completa resistente a la intemperie en un solo producto. Cumple con los requisitos de la norma AAMA 714-22, no requiere imprimaci\u00f3n en la mayor\u00eda de los sustratos y se puede aplicar sobre concreto verde. Cuando se hace referencia a las especificaciones de AU-1 LAB, estas provienen directamente de la hoja de datos t\u00e9cnicos y la gu\u00eda de instalaci\u00f3n de Tower Sealants.<\/p>\n\n\n\n Antes de entrar en los pasos de instalaci\u00f3n, esta tabla abarca las diferencias clave entre el sellado aplicado en l\u00edquido y la cinta de sellado tradicional. Comprender qu\u00e9 hace bien cada producto es lo que ayuda a elegir el enfoque correcto para cada aplicaci\u00f3n.<\/p>\n\n\n\n La siguiente secuencia abarca la instalaci\u00f3n de vanos de obra para ventanas y puertas, que es la aplicaci\u00f3n de sellador l\u00edquido m\u00e1s com\u00fan tanto en proyectos comerciales como residenciales. A continuaci\u00f3n, siguen las secciones de penetraciones y de barrera resistente al agua (WRB) para muros amplios.<\/p>\n\n\n\n La preparaci\u00f3n de la superficie es el paso que determina si la membrana se adhiere y permanece adherida. El sellador l\u00edquido no se adherir\u00e1 de manera confiable a una superficie contaminada, congelada o estructuralmente comprometida. Aqu\u00ed no hay atajos que no le cuesten m\u00e1s adelante.<\/p>\n\n\n\n Elimine toda la suciedad, el polvo, el aceite, el moho, la escarcha y el material suelto de las superficies que se van a tratar. Cualquier da\u00f1o estructural en el armaz\u00f3n o en el entablado debe repararse antes de aplicar la membrana. No aplique sellador l\u00edquido sobre un sustrato da\u00f1ado esperando que la membrana compense.<\/p>\n\n\n\n Para las juntas de los paneles de revestimiento de OSB o contrachapado, selle todas las juntas de las tablas mayores de 1\/4\u2033<\/p>\n\n\n\n antes de aplicar la membrana. El m\u00e9todo recomendado para AU-1 LAB es aplicar un cord\u00f3n generoso de sellador para construcci\u00f3n comercial AU-1 en las juntas y alisar al ras. Permita que el sellador deje de estar pegajoso antes de aplicar AU-1 LAB sobre el \u00e1rea de la junta. Como alternativa, aplique AU-1 LAB sobre la junta e incruste inmediatamente una cinta de malla compatible, alisando la membrana sobre la cinta con una extensi\u00f3n m\u00ednima de 1 pulgada m\u00e1s all\u00e1 de cada borde.<\/p>\n\n\n\n Los sujetadores del entortado deben quedar al ras con la superficie. Cualquier sujetador que sobresalga o est\u00e9 hundido por debajo de la superficie debe sellarse con sellador para construcci\u00f3n comercial AU-1 antes de la aplicaci\u00f3n de la membrana.<\/p>\n\n\n\n Cualquier grieta o espacio no estructural en el sustrato de hasta 1\/2 pulgada debe sellarse con un sellador de construcci\u00f3n elastom\u00e9rico antes de aplicar el sellador l\u00edquido. El sellador de construcci\u00f3n comercial AU-1 es el producto adecuado para este paso cuando se utiliza AU-1 LAB como membrana. Permita que el sellador quede libre de pegajosidad antes de continuar.<\/p>\n\n\n\n Las brechas de m\u00e1s de 1\/2 pulgada requieren reparaci\u00f3n estructural antes de que comience cualquier trabajo con sellador o membrana. El sellador l\u00edquido no es un relleno de huecos para aberturas de gran tama\u00f1o.<\/p>\n\n\n\n AU-1 LAB se puede aplicar con brocha, rodillo o pistola sin aire (airless). La cobertura objetivo es un m\u00ednimo de 30 mils h\u00famedas en toda la abertura irregular, incluyendo 4 pulgadas de cobertura en la superficie de la pared exterior y un traslape de 2 pulgadas en las transiciones de materiales adyacentes. La superficie de la membrana debe estar libre de agujeros diminutos y vac\u00edos. Si todav\u00eda puede ver el sustrato a trav\u00e9s del revestimiento, no ha aplicado suficiente producto.<\/p>\n\n\n\n Trabaje el producto cuidadosamente en las esquinas y alrededor de las cabezas de los sujetadores. Estos son los puntos con mayor probabilidad de desarrollar peque\u00f1os orificios si la membrana se aplica demasiado delgada o muy r\u00e1pido. Aplique producto adicional en cualquier lugar donde la cobertura se vea delgada y permita que quede sin pegajosidad al tacto antes de agregar otra capa. AU-1 LAB se puede aplicar hasta un espesor de 60 mils h\u00famedas sin escurrir si la porosidad del sustrato requiere un espesor adicional.<\/p>\n\n\n\n Para la aplicaci\u00f3n con pistola sin aire (airless), Tower Sealants recomienda un tama\u00f1o de orificio de boquilla de .021 a .025 a 3000 PSI con un caudal de 1.15 a 2.5 galones por minuto. Pase el rodillo inmediatamente despu\u00e9s de rociar para garantizar una cobertura uniforme y eliminar los poros. No conf\u00ede \u00fanicamente en la aplicaci\u00f3n por rociado sin pasar el rodillo.<\/p>\n\n\n\n Coverage rate: AU-1 LAB covers approximately 50 square feet per gallon at 30 wet mils. Coverage will vary based on substrate porosity and application method. Porous substrates absorb more product. Budget for this on concrete masonry unit (CMU) and brick applications.<\/p>\n\n\n\n Do not install windows, doors, or any other components into the rough opening until the membrane has become tack-free. Pressing a window flange into uncured membrane can displace the coating and create gaps. Tack-free time for AU-1 LAB is approximately 60 minutes at standard conditions (75 degrees F, 50 percent relative humidity). Lower temperatures and higher humidity extend this time.<\/p>\n\n\n\n Full cure takes 24 to 72 hours depending on conditions. Most painting and topcoating should not begin until at least 6 to 8 hours after application.<\/p>\n\n\n\n After tack-free time, inspect the membrane visually for pinholes, thin spots, or areas where the substrate is visible. Any area that does not meet the 30-mil minimum or shows voids should be touched up before windows are installed. This inspection takes a few minutes and prevents callbacks that take hours to fix.<\/p>\n\n\n\n A wet mil gauge is the most reliable way to confirm coverage during application. Guessing at thickness is one of the most common causes of membrane underperformance.<\/p>\n\n\n\n The sill is where most window flashing failures begin. Water that gets past the window frame runs down and collects at the sill. If the flashing at the sill is incomplete, that is where it enters the wall assembly. Apply membrane to the sill first, working the product into the corners where the sill meets the jambs. Then work up the jambs and finish with the head.<\/p>\n\n\n\n Extend the membrane a minimum of 4 inches onto the exterior sheathing surface around the perimeter of the opening. On commercial construction with CMU or precast substrates, extend coverage to cover the entire wood buck or rough opening frame. The goal is a continuous membrane with no gaps at any transition.<\/p>\n\n\n\n Allow the membrane to become tack-free before setting the window. Once the window is in place, seal the perimeter joint between the window frame and the surrounding substrate with an appropriate sealant. For exterior commercial work, AU-1 Commercial Construction Sealant is the right product for that joint. For interior painted surfaces, siliconized acrylic is the right call.<\/p>\n\n\n\n Penetrations through the wall assembly are among the most common points of air and water infiltration on any building. Liquid flashing handles these better than tape because it flows around cylindrical and irregular shapes without requiring cuts or origami-style folding.<\/p>\n\n\n\n Apply the membrane around the penetration sleeve, extending at least 4 inches onto the surrounding sheathing surface in all directions. Work the product into the gap between the sleeve and the sheathing to create a continuous seal. For penetrations through CMU or concrete, apply to a minimum of 30 wet mils and inspect for pinholes carefully before covering.<\/p>\n\n\n\n If the penetration gap is larger than 1\/4 inch, fill it with AU-1 Commercial Construction Sealant and allow it to become tack-free before applying the liquid membrane. Do not attempt to bridge gaps larger than 1\/4 inch with membrane alone.<\/p>\n\n\n\n AU-1 LAB can be used as a full weather-resistive barrier across the entire exterior wall field, replacing traditional housewrap. This is one of its primary advantages over liquid flashing products from competitors that are designed only for detail work at openings and penetrations.<\/p>\n\n\n\n Prepare all seams and rough openings as described above before applying the membrane to the field. Apply AU-1 LAB to the full wall surface at a minimum of 30 wet mils using a brush, roller, or airless sprayer with back-rolling. The membrane must be continuous with no pinholes or voids across the entire surface.<\/p>\n\n\n\n AU-1 LAB can be exposed to weather and UV for up to 9 months before requiring coverage via cladding or coating. That extended exposure window is a practical advantage on phased commercial projects where cladding installation follows months after the building envelope is closed in.<\/p>\n\n\n\n Flashing tape is faster on simple, flat openings with square corners and standard framing. An experienced crew can tape a standard window opening quickly when conditions are right. The limitation shows up on everything else.<\/p>\n\n\n\n Liquid flashing is the stronger choice on recessed windows, non-standard opening sizes, complex penetrations, any substrate where tape adhesion is unreliable, and any commercial project where the opening geometry creates more than two corners. It is also the only option when you need a product that can serve as both the detail flashing at openings and the full weather-resistive barrier across the wall field. Liquid-applied flashing protects the building from wind-driven rain, a benefit of this solution over traditional flashing.<\/p>\n\n\n\n On commercial construction where AAMA 714-22 compliance is required, liquid flashing is the specification. AU-1 LAB meets those performance requirements and is tested in accordance with ABAA weather-resistive barrier material standards.<\/p>\n\n\n\n For specification writers, project managers reviewing submittals, or contractors confirming product compliance, here is the technical framework behind AU-1 LAB.<\/p>\n\n\n\n Many competing liquid flashing products on the market reference AAMA 714-15, which is an older version of the standard. When a project spec calls for AAMA 714-22 compliance, verify that the product you are submitting has actually been tested to that version.<\/p>\n\n\n\n AU-1 LAB has been tested in accordance with the performance requirements of the Air Barrier Association of America (ABAA) for weather-resistive barrier materials. Key tested values include average air permeance at 75 Pa of 0.00077084 L\/(Pa.m2.s) passing ASTM E2178-21a, pull-off adhesion of 346.4 psi passing ASTM D4541, and a Flame Spread Index of 10 Class A per ASTM E84. Water vapor permeability passes at 13 perms per ASTM E-96, confirming the membrane is breathable.<\/p>\n\n\n\n AU-1 LAB requires surface and air temperatures above 40 degrees F and rising at time of application. Do not apply to frozen substrates or surfaces expected to freeze within the cure window. Maximum substrate temperature at time of application is 160 degrees F. Service temperature range after full cure is minus 30 degrees F to 180 degrees F.<\/p>\n\n\n\n Coverage at 30 wet mils is approximately 50 square feet per gallon. The product can be built up to 60 wet mils without sagging. Tack-free time is approximately 60 minutes at standard conditions. Full cure takes 24 to 72 hours. The membrane can be exposed to weather and UV for up to 9 months before cladding is required.<\/p>\n\n\n\n The minimum application thickness for AU-1 LAB is 30 wet mils. This is the threshold at which the membrane provides a continuous, void-free film. AU-1 LAB can be applied up to 60 wet mils without sagging on porous substrates that absorb more product. Use a wet mil gauge during application to verify coverage rather than estimating by eye.<\/p>\n\n\n\n AU-1 LAB requires surface and air temperatures above 40 degrees F and rising at time of application. Do not apply to frozen substrates or before conditions where temperatures will drop below freezing before the membrane has cured. Cold temperatures slow cure time and can compromise adhesion. If temperatures are borderline, delay application rather than risk a failed bond.<\/p>\n\n\n\n Wait until the membrane is tack-free before installing windows or doors into the rough opening. For AU-1 LAB at standard conditions, tack-free time is approximately 60 minutes. Actual time varies with temperature and humidity. Test the membrane with a light finger touch rather than relying on time alone. If the membrane transfers to your finger, it is not ready.<\/p>\n\n\n\n Liquid flashing cures into a seamless, chemically bonded membrane that flows into corners, around fasteners, and into irregular shapes without cuts or seams. Flashing tape is an adhesive-backed sheet product that requires lapping and folding at corners, with each overlap being a potential leak point. Liquid flashing outperforms tape on complex geometries and on substrates where tape adhesion is unreliable. For simple standard openings with square framing, tape is faster. For everything else, liquid flashing is the stronger system.<\/p>\n\n\n\n AU-1 LAB does not require a primer on most common substrates including concrete, masonry, OSB, plywood, aluminum, brick, exterior gypsum, and stucco. Adhesion testing is always recommended before full production application on any unfamiliar substrate. On OSB with high wax content in the binder, in-situ adhesion tests should be performed before full application since wax content varies by manufacturer.<\/p>\n\n\n\n Yes. AU-1 LAB is designed for both rough opening detail flashing and broad wall weather-resistive barrier application across the full wall field. This makes it a more versatile system than products designed only for window and door detailing. For full wall WRB application, prepare all seams and rough openings first, then apply the membrane to the field at a minimum of 30 wet mils.<\/p>\n\n\n\n AU-1 LAB passes ASTM D1970 nail sealability testing, meaning it seals around properly installed fasteners without allowing water penetration. Fasteners that are sunk or raised relative to the sheathing surface should be sealed with AU-1 Commercial Construction Sealant before membrane application for best results.<\/p>\n\n\n\n AU-1 LAB can be exposed to weather and UV for up to 9 months before requiring coverage by cladding or coating. This extended exposure window is a practical advantage on commercial projects where cladding installation follows building envelope closure by several months. After 9 months of exposure, confirm the membrane condition before installing cladding.<\/p>\n\n\n\n Knowing how to install a liquid flashing membrane correctly comes down to four fundamentals: clean surfaces, sufficient thickness, tack-free time before component installation, and thorough inspection before covering. Get those right and the membrane performs for the life of the building. Skip one and you are likely looking at a callback.<\/p>\n\n\n\n Tower Sealants AU-1 LAB is built for both rough opening flashing and full weather-resistive barrier applications on commercial construction. It requires no primer on most substrates, applies to green concrete, meets AAMA 714-22 performance requirements, and can function as the single membrane product for the entire building envelope. For contractors working with silicone vs acrylic urethane sealant decisions on the same project, AU-1 LAB integrates directly with AU-1 Commercial Construction Sealant for seam prep and joint sealing at penetrations.<\/p>\n\n\n\n If you have questions about a specific application or want to confirm product compatibility on your project, the Tower Sealants technical team is available to help.

AAMA 714-22<\/strong><\/h3>\n\n\n\n
AAMA 714-22 is the current voluntary specification for liquid-applied flashing used to create a water-resistive seal. AU-1 LAB meets the performance requirements of AAMA 714-22 and the earlier 714-19 standard. This includes passing adhesive bond testing to cement and plywood substrates, water penetration testing around nails, crack bridging through two categories, thermal cycling peel adhesion, and water immersion peel adhesion. The self-sealing properties of AAMA 714-22 are a key factor to this specification.<\/h3>\n\n\n\n
