Dura500DURA 500, is a liquid applied, high tensile, seamless roof membrane that provides permanent restoration for built-up roofing, rolled asphalt, EPDM, TPO, Hypalon®, modified bitumen, and other flat roofing surfaces. The product is a single part coating, based on new SEBS technology (styrene-ethylene-butylene-styrene), also known as thermoplastic elastomer (TPE), and is engineered to provide a service life of well over 20 years. Cold temperature shipping or storage will not harm this coating. DURA 500 is the ultimate, long life, seamless waterproofing solution for flat roofs. Dura 500 exceeds the elongation and tensile strength properties of most mechanically applied membranes.

DURA 500 cures to a tough, impact and abrasion resistant membrane with an amazing tensile strength of 1905 psi. Unaffected by ponding water, UV from sunlight or temperature extremes, DURA 500 can be applied in humid or cold conditions, allowing for an extended application season. Uncured product will not wash off with overnight rain or heavy dew.

DURA 500 can be applied by high pressure airless spray, brush or roller. DURA 500 exceeds US Energy Star and ASTM D6083 requirements for solar reflectivity, and can reduce air conditioning costs by as much as 30%, depending on building design and geographic location. Heat stress on the roof structure is virtually eliminated. Flexible, reflective and impact resistant, DURA 500 provides a highly cost effective solution to re-roofing.

Reflected light can greatly improve solar panel efficiency on flat or low-sloped roofs. Most water-based acrylic coatings will absorb moisture and deteriorate in the presence of standing water or ice. Dura 500 on the other hand, remains unaffected by these conditions and remains flexible, even in extreme cold temperatures. The product self-levels and forms a strong, seamless, membrane with over 90% reflectivity. Dura 500 can be spray applied after solar panel mounts are installed, assuring a tight waterproof seal.


Dura 500 is guaranteed not to chalk, crack or peel for a period of 15 years from the date of application, provided that the coating is applied according to our Specification Guideline. Superior Polymers Inc. accepts no responsibility for any applicators inability to detect and properly seal leaks. In order to ensure good adhesion and leak protection, proper cleaning, surface preparation and coating methods must be used, and these methods are the sole responsibility of the applicator. Applicators are responsible for all warranties pertaining to workmanship, surface preparation, structural roof repairs, installation of Dura 500, and any subsequent inspection and maintenance programs. Ponding water issues must be corrected in accordance with good roofing practices. If the coating does not perform as stated during the guarantee period, Superior Polymers Inc. will provide the original purchaser with replacement coating to repair the affected part of the coating. Failures due to acts of God, fire, structural defects, mechanical damage, intentional or accidental, are excluded from this guarantee. Superior Polymers Inc. is not responsible for any labor, property or other consequential damages or costs incurred in the original or any replacement application. Except as stated above, we make no warranties or guarantees, expressed or implied, and none should be inferred.
