How-To Steps

1. Surface Preparation: Ensure the substrate is clean, dry, and free from dust, grease, and loose particles. Degrease metal surfaces. The surface and ambient temperature should be between +5°C and +30°C.
2. Priming: For highly absorbent surfaces, prime with a 1:2 mixture of sealant and water. Allow the primer to dry for approximately 1 hour.
3. Application: Insert the cartridge into a professional caulking gun. Apply the sealant into the joint, ensuring full contact with the surfaces to avoid air pockets. For optimal joint design, use a closed-cell backer rod.
4. Tooling: Immediately after application, tool the sealant with a wetted spatula, trowel, or finger to achieve a smooth, professional finish.
5. Curing: Protect the joint from moisture and rain during the initial curing phase. The sealant is typically paintable after it has fully cured (1-3 days).

Recommendations

For joints wider than 20mm or with movement exceeding ±10%, a higher-performance elastomeric sealant is recommended. Always perform a preliminary test to confirm compatibility with specific paints, especially matte finishes. When used externally, ensure the joint is protected from rain until a skin has formed.
