Excellent for adhering to damp surfaces.  Great for gutters and down spouts, metal storm windows, doors and lap joints, and awning applications.

Sila-Seal Butyl Caulk is a single component, “solvent release” butyl, designed to provide excellent exterior weathering properties. Sila-Seal Butyl Caulk is formulated for use on many dissimilar building surfaces. It is our best narrow-bead sealant, and is ideal for sealing gutter down spouts, metal storm windows, doors and lap joints. Sila-Seal Butyl Caulk adheres well to damp surfaces.

FEATURES & TYPICAL USES:

Sila-Seal Butyl Caulk is for use in areas where a sealant of more resiliency than ordinary caulk is required. Principal use is to seal narrow seams. Sila-Seal Butyl Caulk is excellent under shower tracks or metal thresholds and other exterior building materials.  Sila-Seal Butyl Caulk can be used successfully on metal, glass, wood, brick, stone, masonry and paint to prevent the passage of air and moisture through narrow openings, whether the construction materials are similar or dissimilar. Sila-Seal Butyl Caulk is not recommended where joints will have extreme movement or where openings are over 9.5 mm (3/8”) wide.

Easy application - Can be easily applied with standard caulking guns or power caulking equipment.

Exceptional adhesion - Adheres well to most exterior sealing applications.

High durability - Will not crack and is resistant to sunlight, ozone, water, vapor transmission, cleaning chemicals and weathering.

Good stretch recovery - Will recover 70% of 100% elongation.

Extensive flexibility - Remains flexible over an extreme temperature range.

Optional painting - Forms a skin within 24 hours. Painting is unnecessary, but if desired can be done after product has cured for one week. Sila-Seal Butyl Caulk is non-staining, with no discoloration.

SURFACE PREPARATION & APPLICATON:

The surface to be caulked should be sound, clean and dry, and be free of oil, grease, rust, corrosion or loose paint. A primer may be required for certain surfaces. Sila-Seal Butyl Caulk should not be applied when temperature is 40°F (4°C) or less. Sila-Seal Butyl Caulk should be at room temperature when applied. If the sealant has been stored in a cool area, place in a heated room for several hours before using. Cut tip of nozzle to desired bead size. Insert cartridge into standard caulking gun to apply, or use any power equipment for normal caulking compounds or sealants. This product may be smoothed with a knife dipped in mineral spirits or water. Clean tools with mineral spirits or paint thinner. Care should be exercised when using   Sila-Seal Butyl Caulk on certain types of plastic.
