💡 Application tips

🔹 Best practices

For optimal results:

• Apply on clean, dry and grease-free surfaces
• Lightly sand metal surfaces if necessary
• Assemble parts before skin formation (~8 minutes)
• For large surfaces, ensure at least one permeable substrate
• Hold components in place during curing

Clean tools immediately after use (before curing).

⚠️ Limitations

• Not suitable for certain non-ferrous metals
• Adhesion should be tested beforehand
• Not recommended for specific applications without prior testing
