StoSeal STPE™ Sealant: Your All-in-One Sealant Solution for Building Restoration

High-performing, elastomeric, one-part hybrid StoSeal STPE™ Sealant combines polyurethane’s strength and silicone’s weather resistance to provide an all-in-one solution for above-grade, vertical building restoration (and new opaque wall) applications. StoSeal STPE™ Sealant will contribute significantly to the long-term weather resistance of the building envelope.

Building Restoration

Designing a code-complaint building restoration project with an airtight building envelope requires correctly applying a quality sealant. A high-performing, elastomeric, flexible sealant prevents the passage of liquids, light, or gasses between two materials despite movement between those components.

It’s important to know that the quality of the sealant you choose for a building restoration project can affect its service life and, ultimately, the long-term airtightness and weatherproofing performance of the building’s envelope.

Building Restoration Sealant 

Sealant is used to seal, block or close gaps between building materials to prevent fluids, air and other substances from passing through. Building restoration projects often require the removal and replacement of sealant. Builders can use it for numerous applications, including:

  • Expansion joints to allow for thermal movement of the building
  • Air seals at interior or exterior joints and seams to provide air barrier continuity
  • Panel-to-panel joints between precast, metal frame, and other prefabricated wall construction
  • Control joints
  • Deflection joints sealant at floor lines
  • As a bedding sealant for flashing, flanged windows, and related applications
  • Perimeter weather seals around doors, windows, scuppers, and other through-wall penetrations
  • Perimeter weather seals around fixture attachments

Specifying the proper sealant will ensure the sealant performs as intended and reaches its maximum service life.  Proper design and installation of the sealant will maximize the building envelope’s service life and limit the potential need for costly repairs which could result from water intrusion. A properly performing sealant also prevents excessive air movement which affects occupant comfort and contributes to energy costs during the building’s service life.

StoSeal STPE™ Sealant: Your All-in-One Solution for Building Restoration

Applying a high-performing sealant for building restoration, like StoSeal STPE™ (silyl terminated polyether) sealant, will maintain a positive seal between the joint opening’s substrates, and provide long-term resistance against the passage of heat, light, sound, air, rain, snow, wind, odor, dust, and chemical and biological contaminants. It will also protect against the damaging effects of UV rays, thermal cycles, moisture, and structural movement.

StoSeal STPE™ Sealant combines the strength of polyurethane and the weather resistance of silicone to create a long-lasting weatherproofing sealant with superior adhesion, strength, and flexibility. StoSeal STPE™ Sealant bonds to most construction materials (cement, stucco, masonry, stone, concrete, wood, common metals and fiber cement). 

Preserving the Past: Restoring Old Buildings for Future Generations

StoSeal STPE™ Sealant’s superior adhesive properties work effectively with StoVentec®, StoTherm® ci, StoPowerwall®, and StoQuik® exterior wall systems and with StoGuard® air- and water-resistive barrier systems for above-grade, vertical building restoration (and new opaque wall) applications. You can use it for concrete repair, panel-to-panel joints in prefabricated construction, interior use, metallic and cementitious substrates, storefront systems, and air sealing applications.

Advantages and Features of High-Quality StoSeal STPE™ Sealant

StoSeal STPE™ technology creates a one-part hybrid sealant that have several high-performance features beneficial to building restoration, including:

    • Eco-Friendly: StoSeal STPE™ Sealant lacks isocyanates and contains very low VOC (8 grams per liter) – it will not bubble and it release very little odor
    • High-Movement: Offers +100%/-50% movement – acceptable for high and low movement joints, to effectively endure structural movement 
    • Superior Adhesion: Will bond to most construction products, like concrete, wood, plastics, ceramics, and metals, without a primer
  • Streamlines Installation
      • Simple to gun and tool
      • Primer-free bonding to most substrates
      • Sold in 20-ounce sausages that minimize construction waste and offer efficient installation
  • Paintable with Elastomeric Coatings
    • Allows for top coating with elastomeric coatings to suit most color needs
    • Sold in ten standard and over 300 custom colors
  • Durable: Long-lasting StoSeal STPE™ Sealant provides excellent UV-. moisture-, weathering-, aging-, and shrinkage-resistance
  • Cold Resistant: StoSeal STPE™ Sealant retains its properties to -50°F (-45°C)
  • Non-Reactive: StoSeal STPE™ Sealant will not corrode or oxidize metals
  • Storage Stable: When properly stored, the sealant will last 12 months in original, unopened packaging

StoSeal STPE™ Sealant Compliance Testing

StoSeal STPE™ Sealant complies with:

  • ASTM C1382 for use with EIFS
  • ASTM C920: Type S, Grade NS, Use NT, A, M, Class 100/50
  • Federal Spec. TT-S-00230C Type II
  • AAMA 808.3 (Type1) Exterior Perimeter Sealing
