• Sealing of finished terminations, edges of patches and overlaps in detail areas
• Sealing penetrations through GCP air and weather barrier systems, such as plumbing or ductwork
• As a sheathing joint treatment for GCP fluid-applied air and weather barrier membranes
• For sealing between window flanges and the air and weather barrier system.

Product Advantages

• No primer—fast and easy application with minimum surface preparation
• No staining or residue rundown
• High movement capability
• Adhesion—Strong adhesion to common construction substrates, such as wood, block, concrete, OSB, glass mat sheathing, metal, vinyl and PVC
• Compatibility—Compatible with most GCP air and weather barrier systems

Application Procedures

Safety, Storage and Handling Information

Read and understand the product label and Safety Data Sheet (SDS) for each system component. All users should acquaint themselves with this information prior to working with the products and follow the precautionary statements. SDSs can be obtained by contacting your local GCP representative or office, by calling GCP toll free at 1-866-333-3SBM (3726) and in some cases from our web site at gcpat.com.
 
S100 Sealant is available in two different sizes 20 fl oz (0.591 L) sausages and 29 fl oz (0.858L) cartridges. S100 Sealant has a shelf life of 12 months from the date of manufacture when stored in the original unopened sausages between 40°F (4°C) and 80°F (27°C).

The Volatile Organic Compound (VOC) content is <30 g/L.

Surface Preparation

All surfaces must be clean, dry and free from dirt, grease oil, dust or other contaminants. S100 Sealant may be applied at temperatures above 20°F (-6.67°C) and above.

Product Application

Apply S100 Sealant with a caulking or sausage gun. When used as a seal for finished terminations, edges of patches and overlaps in detail areas, level the bead with a trowel to a minimum 0.125 in. (3 mm) thickness and 0.5 in. (13 mm) to 1 in. (25 mm) width.

When sealing penetrations, apply a 1 in. (25 mm) fillet to the base of the penetration and overlap onto the GCP air and weather barrier material and penetrant a minimum of 2.5 in. (64 mm).

When used to treat sheathing joints for GCP fluid-applied air and weather barrier membranes, completely fill the sheathing joint with sealant and then install a scratch coat of sealant with a margin trowel or similar onto the face of the sheathing approximately 1 in. (25 mm) on each side of the sheathing joint. Once the sealant is tack free, the fluid applied membrane may be applied, refer to the applicable product data sheets for detailed application instructions.

Cleaning

Clean tools and equipment with mineral spirits. Mineral spirits is a combustible liquid and should be used only in accordance with the mineral spirits manufacturer’s safety recommendations. Do not use solvents to clean hands or skin.

Limitations

S100 Sealant should not be used in the following applications:

• Below grade
• End of day terminations
• Under GCP air and weather barrier membranes and flashing, except when used as a joint treatment for GCP fluid-applied membranes.
• Not for use with building materials that bleed oils, plasticizers or solvents
• Firestopping applications
