Sealant for Metal Sheets Soudal Colozinc transparent 290 ml

Soudal Colozinc transparent sealant in a 290 ml cartridge is formulated for sealing and repairing metal sheets and associated roof and façade details. The clear, weather-resistant sealant adheres to zinc, galvanized and painted metal surfaces to create a discreet, durable joint that helps prevent water ingress and reduces the risk of corrosion. The product is intended for outdoor use on roofs, flashings and other metal connections where an unobtrusive, transparent finish is required.

Advantages

The sealant provides a transparent finish that preserves the appearance of metal surfaces while maintaining flexibility and adhesion under changing weather conditions. It resists moisture and contributes to corrosion protection by sealing gaps and seams. The cartridge format is compatible with standard caulking guns, enabling controlled application and efficient use for spot repairs and continuous joints.

Suitable for

• Sealing gaps and seams on zinc and galvanized metal sheets
• Repairing flashing, seams and overlaps on roofing
• Spot sealing painted metal components on façades and trims
• Preventing water ingress at joints and around fasteners

Key specifications

• Color: transparent/clear
• Volume: 290 ml cartridge
• Material type: polymer-based sealant formulated for metal substrates

How to use

Ensure surfaces are clean, dry and free from rust, loose paint, oil or other contaminants before application. Cut the cartridge tip to the desired bead size and apply using a standard caulking gun, maintaining steady pressure to form a continuous bead. Tool or smooth the joint within the product’s skinning time to ensure adhesion and a neat finish. Allow the sealant to cure fully according to ambient temperature and humidity before exposing the joint to heavy moisture or mechanical stress.

Usage recommendations

For best results, test adhesion on a small inconspicuous area of painted metal prior to full application. Avoid applying the sealant at temperatures outside the manufacturer’s recommended range and do not use on continuously submerged surfaces. When working at heights, follow applicable safety measures for roof work and use appropriate fall protection.
