Preparation
Ensure that all surfaces to be sealed are clean, dry, sound, and free from grease. For non-porous surfaces, clean with DOWSIL™ R-40 Universal Cleaner or methylated spirits, then dry thoroughly with a clean, lint-free cloth that is free of oil.
Note: When using any solvent, ensure proper ventilation. Avoid heat, sparks, and open flames, and wear solvent-resistant gloves. Always follow the safety precautions listed on the solvent container label.
Application
For best results ensure adequate preparation is preformed before application.
- To ensure a clean and neat application, mask areas adjacent to the joints with tape. This prevents contamination of surrounding surfaces and ensures a straight, uniform sealant line. Remove the masking tape immediately after tooling for a crisp finish.
- For joints that require backup material, a closed-cell polyethylene backer rod is recommended.
- In shallow joints, use low-tack polyethylene tape as a backer. These materials help provide proper back pressure and prevent three-sided adhesion, ensuring optimal sealant movement.
- Tool the joint within 5 minutes of applying the sealant to ensure good contact with the substrate. Tooling also provides a smooth, professional finish, ensuring long-lasting performance.
- The sealant joint width should accommodate the movement capability of the sealant.
- Minimum joint width for DOWSIL 785 Sanitary Acetoxy Silicone should be 6 mm.
- For joints between 6–12 mm wide, a seal depth of 6 mm is required.
- For joints wider than 12 mm, use a width-to-depth ratio of 2:1.
- For fillet joints, ensure a minimum of 6 mm sealant bite to each substrate.
