Pecora® Sil-Span™: Eliminates the Need for Expensive Sealant Cutouts and Prevents Damage to Building Substrate

Joint sealant failures are a common occurrence over the lifespan of a building and can result in substantial damage to the property.  Repairing these failures can be extremely costly and time consuming particularly in exterior insulation and finish systems (EIFS).

Pecora’s Sil-Span preformed silicone profiles provide an alternative to the traditional method of repairing failed sealant joints eliminating the costly steps of removing the existing failed sealant and the surface preparation that can often damage the substrate.  It offers a cost-effective method of correcting failures in areas of the building envelope which are difficult or almost impossible to replace or reseal such as curtain-walls, stucco, skylights, roofing details, reglets, coping stones and flashing details.

"I like the versatility of Sil-Span in solving waterproofing issues with EIFS and skylights,  both leak-prone and difficult to seal using conventional methods,” says says Alan Johnson, partner of Streamline Waterproofing of Derry, NH.   “The ability to offer a textured custom color for failed EIFS joints and custom bend lines to bridge leaking mullions resolves issues while maintaining aesthetics."

A specially formulated low-modulus silicone compound, Sil-Span is extruded into preformed strips or custom shapes that  ”bridge” over the existing joint waterproofing the building envelope while maintaining the original aesthetics of the substrate.  This cost effective alternative provides the benefits of:

• Reduced labor costs and easy application
• No EIFS substrate damage common in restoration
• The perfect look – Sil-Span can be custom colored and textured to match virtually any finish

“The field crew liked working with Sil-Span because it was so easy to install”, says Jaime Gaumnitz of Western Waterproofing in Renton, WA.   “And the consultants were happy because it eliminated the cost of a cutout,  prevented damage to the substrate  and it kept out moisture.” 

In addition to the ease of application, Sil-Span meets ASTM C 1523, is validated by Sealant Waterproofing & Restoration Institute and provides the properties of advanced silicone technology. 

• 200% movement capability
