Area Exterior
Recommended Use Sealing PVC-U, glass, glazed surfaces, and brickwork
Drying Time Tack free: 35 minutes
Application Method Sausage Gun/ Geocell Ecoseal Sleeve Plastic Cartridge
Clean Up Excess sealant can be cleaned from tools and non-porous surfaces while uncured using DOWSIL™ R-40 Universal Cleaner. If applied to porous substrates, allow it to cure partially, then remove by peeling, cutting, or other mechanical means. Avoid damaging plastic or coated surfaces.
Preparation

Ensure that all surfaces to be sealed are clean, dry, sound, and free from frost. Remove any release agents, water repellents, laitance, dust, dirt, old sealants, or other contaminants that could affect adhesion. For non-porous surfaces, clean and degrease using a suitable solvent, such as DOWSIL™ R-40 Universal Cleaner, applied with an oil- and lint-free cloth. For porous substrates, clean mechanically using a steel brush, sanding disc, or similar tool.

Note: When using solvents, ensure proper ventilation. Avoid heat, sparks, and open flames. Wear solvent-resistant gloves and follow all safety instructions on the solvent container label.

Application
  • Masking: Mask areas adjacent to the joints with tape to prevent substrate contamination and ensure a neat sealant line. Remove the masking tape immediately after tooling for a clean finish.
  • Priming: No primer is required for PVC-U and most common construction substrates, including brick. However, it is recommended to conduct a test placement before general use to ensure proper adhesion.
  • Back-Up Materials: Use a closed cell polyethylene backer rod as a backup material to provide back pressure and prevent three-sided adhesion, which could limit the sealant's movement capability. For shallow joints, use low-tack polyethylene tape instead of a backer rod.
  • Joint Design: The sealant joint width must accommodate the sealant's movement capability.
    • Minimum joint width: 6 mm
    • For joints between 6–12 mm, a seal depth of 6 mm is required.
    • For joints wider than 12 mm, use a width-to-depth ratio of 2:1.
    • For joints larger than 25 mm, consult your regional service center for guidance.
    • In fillet joints, ensure a minimum of 6 mm sealant bite to each substrate.
  • Tooling: Tool the joint within 5 minutes of application to ensure proper contact between the sealant and substrate. Tooling also creates a smooth, professional finish.
  • Aftercare & Storage
    When stored in the original unopened containers at or below 30°C (86°F), DOWSIL 796 Silicone Sealant has a shelf life of 12 months from the date of manufacture.
