Silicone Construction Sealants


Maximize jobsite flexibility and structural protection while minimizing costs with Pecora’s innovative line of silicone sealants solutions. Our silicone construction sealants are designed to eliminate the staining of porous substrates, reduce the need to repair or remove aged and failing sealant, and to reduce the cost of wasted product on the jobsite.

Some of Pecora’s innovations in high-performance silicone construction sealant solutions include:

  • Unprecedented Flexibility with 890FTS and 890FTS-TXTR Silicone Sealants – high-quality, non-staining silicones that can be quickly and easily tinted at the jobsite. Pecora’s 890 Field Tintable Silicone line is the industry’s first to include a textured option. Perfect for historic restoration where stone and grout have previously been utilized. Used in conjunction with our Universal Color Packs, you have 51 standard color options to choose from. Custom color packs provide you with the flexibility of virtually any color your specific project requires. Pecora’s 890FTS and 890FTS TXTR eliminate waste and reduce your overall jobsite costs by allowing you to select your amount, select your color and select your appearance.


  • NST Non-Staining Technology™ Don’t Stain Your Reputation® offering the industry’s first complete line of non-staining silicones. We have removed the free fluids that are commonly associated with substrate staining as well as the residue rundown often seen on glass and metal panels. By removing the possibility of fluid migration Pecora has virtually eliminated the possibility of staining and residue rundown. NST silicones also provide the additional benefits of increased adhesion and reduced dirt pick up as compared to traditional silicones.

  • Sil-Span preformed profiles are an alternative to the costly removal of aged, failed sealant or costly substrate repair. Sil-Span allows you to simply bridge over the joint or glazing detail with a pre-formed low modulus profile that can be textured and colored to match your substrate.
