Q: What are “Cool Roof Coatings”?<\/strong><\/h4>\n

A:<\/strong> Por favor refi\u00e9rase a esto\u00a0gu\u00eda<\/a>.<\/p>\n

P: \u00bfPor qu\u00e9 elegir los revestimientos para techos de Lucas?<\/h4>\n

A:<\/strong> Por favor refi\u00e9rase a esto\u00a0gu\u00eda<\/a>.<\/p>\n

P: \u00bfCu\u00e1les son las recomendaciones de aplicaci\u00f3n por aspersi\u00f3n de Lucas Coatings?<\/h4>\n

A:<\/strong> Por favor refi\u00e9rase a esto\u00a0gu\u00eda.<\/a><\/p>\n

P: \u00bfCu\u00e1les son mejores, los recubrimientos elastom\u00e9ricos de curado por humedad, a base de agua o solventes?<\/h4>\n

A:<\/strong> Los recubrimientos de curado por humedad, a base de agua y solventes tienen sus ventajas.<\/p>\n

Solvent based tend to be more waterproof, can be used in colder weather, won’t freeze, are less affected by humidity and rain after application and will adhere to certain surfaces, such as TPO, that water-based coatings often will not.<\/p>\n

Water based coatings are lower odor, are “breathable” so are more suitable for masonry, are less prone to “bleed through” or discoloration when applied over asphalt and are generally easier to spray as they don’t change viscosity significantly at different temperatures<\/p>\n

Los recubrimientos de curado por humedad permiten s\u00f3lidos de hasta 1001 TP2T, por lo que el espesor de la pel\u00edcula por volumen aplicado es mayor. Generalmente son de bajo olor y bajo VOC. Las ventajas y desventajas son una vida \u00fatil m\u00e1s corta y una adhesi\u00f3n limitada a algunas superficies, incluidos TPO y asfalto que requieren imprimaciones. Si bien no se congelar\u00e1n, los revestimientos de curado por humedad no se curar\u00e1n normalmente cuando las temperaturas est\u00e1n por debajo del punto de congelaci\u00f3n y hay poca humedad libre en el aire.<\/p>\n

P: \u00bfQu\u00e9 es el punto de roc\u00edo y por qu\u00e9 es importante?<\/h4>\n

A:<\/strong> El punto de roc\u00edo es el punto en el que la humedad del aire se condensa en agua l\u00edquida. Muchos revestimientos de Lucas requieren una superficie seca. Las superficies pueden parecer secas, pero la humedad se condensar\u00e1 a medida que se aplique el revestimiento porque la aplicaci\u00f3n del revestimiento a menudo bajar\u00e1 la temperatura de la superficie del techo en el punto de aplicaci\u00f3n, lo que provocar\u00e1 que las gotas de agua l\u00edquida queden atrapadas debajo o encapsuladas en el revestimiento. Consulte esta tabla para obtener m\u00e1s informaci\u00f3n:<\/p>\n

P: \u00bfQu\u00e9 son la reflectividad y la emisividad y por qu\u00e9 son importantes?<\/h4>\n

A:<\/strong> La reflectividad es el porcentaje de energ\u00eda solar reflejada por el revestimiento de regreso a la atm\u00f3sfera. La energ\u00eda restante que se absorbe aumenta la temperatura de la superficie del techo. Una mayor reflectividad da como resultado una menor energ\u00eda absorbida, lo que da como resultado una menor ganancia de calor potencial.<\/p>\n

La emisividad es una medida de la capacidad de los recubrimientos para emitir energ\u00eda solar absorbida como radiaci\u00f3n infrarroja. una mayor emisividad generalmente dar\u00e1 como resultado una superficie m\u00e1s fr\u00eda para dos materiales con la misma reflectividad. La relaci\u00f3n entre la emisividad y la temperatura del techo se complica por factores como la conductividad de la superficie del techo y la velocidad del viento que permitir\u00e1n que algunas superficies de menor emisividad arrojen energ\u00eda t\u00e9rmica de manera m\u00e1s eficiente.<\/p>\n

P: \u00bfQu\u00e9 tipo de recubrimiento es m\u00e1s eficiente energ\u00e9ticamente, el negro, el aluminio o el blanco?<\/h4>\n

A:<\/strong> La respuesta depende del clima y del porcentaje de energ\u00eda utilizada para calentar y enfriar una estructura. En climas c\u00e1lidos, el blanco es m\u00e1s eficiente, en climas templados, los recubrimientos de aluminio con alta reflectividad y menor emisividad brindan el mejor resultado. En las regiones del extremo norte, los techos de colores oscuros ahorrar\u00e1n la mayor cantidad de energ\u00eda ya que el aire acondicionado es poco com\u00fan.<\/p>\n

Q: What’s the difference between asphalt and coal tar?<\/h4>\n

A:<\/strong> Asphalt is derived from crude petroleum. It’s an aliphatic or ‘straight-chain’ hydrocarbon resin. Coal tar is derived from the destructive distillation or coal. It is an aromatic ‘ring shaped’ hydrocarbon resin. The two are different and generally incompatible. Asphalt is normally lower in cost, can be used on pitched roofs to vertical, has fair resistance to UV degradation and can be left bare or surfaced in a variety of manners, but it has poor resistance to ‘ponding’ water. Coal Tar can only be used on near to dead level roofs and has poor resistance to UV degradation so it must always be surfaced with a layer of gravel, pavers or vegetation. Coal tar has good resistance to ponding water and exhibits ‘cold flow’ or ‘self-healing’ characteristics.<\/p>\n

P: \u00bfC\u00f3mo noto la diferencia?<\/h4>\n

A:<\/strong> There are a number of indications as to the type of built up roof. The first is that coal tar is always surfaced with gravel, pavers or vegetation. If it,s bare, coated or surfaced with sprayed in granules, it’s asphalt. If it is a gravel roof the simplest method to determine the type of roof is to wipe the roof with a clean rag soaked in mineral spirits paint thinner. Mineral spirits is an aliphatic solvent and is only capable of dissolving asphalt, which is aliphatic as well. Asphalt roofs will leave a black or dark brown residue on the cloth while coal tar will leave a yellow or slightly green residue. Several passes with a clean cloth may be necessary if the roof is dirty.<\/p>\n

P: \u00bfQu\u00e9 permite que los cementos para techos de superficie h\u00fameda se adhieran a las superficies h\u00famedas o debajo del agua?<\/h4>\n

A:<\/strong> An oil soluble ‘surfactant’ or soap is added to the mastic. The surfactant lowers the surface tension of the mastic and allow the moisture present on the roof to be displaced. Pressure will be necessary to aid in adhesion of the mastic to wet surfaces. These surfactants also promote penetration of, and adhesion to, polyester reinforcing fabrics.<\/p>\n

Q: Aren’t all asphalt roof cements the same?<\/h4>\n

A:<\/strong> No, algunos fabricantes agregan grandes cantidades de relleno, fueloil recuperado (generalmente catalogado como destilado de petr\u00f3leo) \u00a1e incluso hasta 20% de agua! Los rellenos no solo aumentan el peso total del material, sino que tambi\u00e9n pueden reducir el rendimiento a largo plazo. Algunos cementos para techos disponibles comercialmente pesan m\u00e1s de 12 libras. por gal\u00f3n (60 libras por balde de 5 galones). En contraste, los cementos para techos Lucas pesan de 8.3 a 8.5 lbs. por gal\u00f3n (42 a 45 libras por balde de 5 galones).<\/p>\n

Q: What’s the difference between Lucas ‘Standard Grade’ and ‘Premium Grade’ cements and coatings?<\/h4>\n

A:<\/strong> Lucas Premium Grade roof cements and coatings are manufactured from higher softening point asphalts which causes them to cure faster, age more slowly, and resist oxididative cracking or ‘alligatoring’. Lucas Premium roof coatings can take roof traffic sooner and Lucas Premium roof cements will adhere to vertical surfaces without sagging, even when hot mopped. Lastly, Lucas Premium roof cements contain no unnecessary fillers like limestone dust (calcium carbonate), kaolin clay or slate flour. These fillers not only increase the sheer weight of the material but can also reduce long term performance.<\/p>\n

P: \u00bfC\u00f3mo debo evaluar la calidad relativa de los diferentes revestimientos de aluminio para techos?<\/h4>\n

A:<\/strong> Unfortunately there is no clear standard beyond the minimum requirements of ASTM D-2824, which all Lucas Aluminum Coatings meet. The reputation of the manufacturer is paramount. The simplest method to sort out aluminum coating is by aluminum pigment content. Some people object to this standard by claiming that a coating with 2 lbs. of ground up aluminum cans would rate the same as a coating with 2 lbs. Of high quality leafing aluminum paste. For this reason we recommend that users ensure that, when aluminum coatings are graded by pigment weight, the aluminum paste is quoted as meeting ASTM D-962 type 2 – Specification for Aluminum Powder and Paste Pigments for Paints. Another excellent source of information is the EPA’s Energy Star Program which lists reflectivity values of various roofing materials.<\/p>\n

P: \u00bfCu\u00e1ndo se debe aplicar el recubrimiento de techo de aluminio a un nuevo techo de asfalto o bet\u00fan modificado? \u00bfTan pronto como sea posible o despu\u00e9s de que el techo se haya curado?<\/h4>\n

A:<\/strong> El mejor momento para aplicar el revestimiento de techo de aluminio a un techo reci\u00e9n construido es despu\u00e9s de que el techo se haya curado por completo. Esto llevar\u00e1 al menos 6 semanas. La aplicaci\u00f3n de revestimiento de techo de aluminio al asfalto sin curar probablemente dar\u00e1 como resultado una fuga de azufre y aceite y, a veces, grietas o grietas graves.<\/p>\n

El bet\u00fan modificado con SBS se debe recubrir tan pronto como sea posible.<\/p>\n

APP modified bitumen is the most challenging roof to coat with aluminum roof coating. Applying the coating immediately will reduce ‘exudation’ or bleed through, but it will not be eliminated, expect temporary discoloration. Waiting until the membrane has cured will allow most of the exudate to bleed out. If the roof has positive drainage the exudate will wash off the roof and the modified bitumen will present a clean and stable substrate. Roofs with ‘bird baths’ may retain exuded oil and sulfur compounds in low areas. This retained contamination will interfere with adhesion, discolor the coating and can cause the coating to crack. This contamination should be removed with a suitable power washer and detergent. It is the prerogative of the roofing contractor to examine the conditions present on a particular roof and choose the appropriate action. If there is any doubt please contact our technical personnel.<\/p>\n

Q: Are all ‘rubberized’ roof cements ‘elastomeric’?<\/h4>\n

A:<\/strong> Not necessarily. Rubberized means that ‘rubber’ has been added to the mix. Elastomeric implies that the material has the rubber like properties of elongation and recovery. Some ‘rubbers’ such as butyl, neoprene and SBR will not impart elastomeric qualities on an asphalt mixture. ‘Rubbers’ such as SBS and SEBS will, but only if added in sufficient quantities to an asphalt that is suitable and not overly corrupted with economizing fillers.<\/p>\n

Q: What is the difference between ‘waterproofing’ and ‘damproofing’?<\/h4>\n

A:<\/strong> La impermeabilizaci\u00f3n resistir\u00e1 la penetraci\u00f3n de humedad a trav\u00e9s de un cimiento hacia el interior en condiciones normales. La impermeabilizaci\u00f3n har\u00e1 lo mismo incluso en presencia de presi\u00f3n hidrost\u00e1tica.<\/p>\n

P: \u00bfCu\u00e1les son las ventajas y desventajas de aplicar recubrimientos con brocha, rodillo y rociador?<\/h4>\n

A:<\/strong> Brush application allows the coating to be ‘worked in’ to the surface. This will ensure an adequate bond, particularly if the surface is less than ideally clean and smooth. Brush application is the most time consuming method and will often result in visible brush marks.<\/p>\n

Los rodillos son m\u00e1s r\u00e1pidos que las brochas y todav\u00eda permiten una medida de asistencia mec\u00e1nica en la adhesi\u00f3n a la superficie. Los rodillos tambi\u00e9n eliminan las marcas de pincel, pero a\u00fan pueden dejar una superficie texturizada. Los aplicadores deben saber que los rodillos reducir\u00e1n la tasa natural de cobertura por debajo de lo recomendado.<\/p>\n

Spray application is the fastest method of coatings application and generally leaves the smoothest surface. Total lack of mechanical assistance in adhesion, difficulty in assessing coverage rates and the danger of ‘over-spray’ limit the suitability spray applications.<\/p>\n

P: \u00bfCu\u00e1l es la diferencia entre silanos, siloxanos y silicona?<\/h4>\n

A:<\/strong> All three are silicon based molecules that have masonry waterproofing applications. Silanes are monomers, the smallest and most simple of the three molecules. Silanes are best suited for dense surfaces like concrete and cultured stone. High concentrations of about 40% are necessary because of silane’s volatility.<\/p>\n

Los olig\u00f3meros de siloxanos son mol\u00e9culas m\u00e1s grandes y complejas que los silanos. En concentraciones m\u00e1s bajas, brindan una excelente protecci\u00f3n contra la humedad en superficies m\u00e1s porosas, como bloques de concreto de cara partida. Los siloxanos se pueden mezclar con silanos para producir un tratamiento con las ventajas de ambos materiales.<\/p>\n

Silicone polymers are large functional molecules that are used in caulks and sealants. Silicones can be useful for protecting porous natural stone that has a neutral ph. For concrete and masonry applications, silanes and siloxanes penetrate farther and preserve the surface’s original appearance.<\/p>\n

P: \u00bfQu\u00e9 tipo de aislamiento es adecuado para paredes de cimientos por debajo del nivel del suelo?<\/h4>\n

A:<\/strong> El poliestireno extruido y la fibra de vidrio r\u00edgida son los dos tipos de aislamiento m\u00e1s adecuados. El poliestireno es econ\u00f3mico y ampliamente disponible. Sin embargo, el poliestireno no permite que el agua drene hacia el desag\u00fce, es incompatible con los sistemas a base de solventes y no se recomienda su uso en \u00e1reas donde se encuentran termitas porque proporciona una ruta protegida desde la tierra hasta la estructura de madera.<\/p>\n

La fibra de vidrio r\u00edgida es el tipo de aislamiento m\u00e1s adecuado para cimientos subterr\u00e1neos. Es resistente a la descomposici\u00f3n, no alberga plagas y arroja agua de manera eficiente a la loseta de desag\u00fce.<\/p>\n

P: \u00bfSe requiere un informe de evaluaci\u00f3n ICC para la impermeabilizaci\u00f3n con asfalto modificado con pol\u00edmeros?<\/h4>\n

A:<\/strong> No, a research report is not required for polymer modified asphalt waterproofing provided it is applied at a minimum thickness of 40 dry mils. 40 mils of polymer modified asphalt is an ICC “approved method” for complying with IRC 406.2. Only unapproved methods require a research report.<\/p>\n

Q: What is the difference between a “masonry paint” and a “waterproof masonry coating”?<\/h4>\n

A:<\/strong> Masonry “paints” are intended as decorative finishes for masonry walls. Waterproof masonry coatings are performance coating systems that offer breathable moisture protection and crack bridging abilities in addition to decoration.<\/p>\n\t
