Application
- Remove dirt, dust, cement, old sealant and other residues from the surfaces. PU foam and concrete panel surfaces must be free of cracks, cavities and chips; repair defects larger than 6 mm. In winter, remove ice and frost. The sealant can be applied to dry or damp surfaces, but water droplets must not be present. Apply no earlier than 24 hours after applying the PU foam. Degrease surfaces adjacent to the foam; KUDO® Universal Degreaser is recommended. Caution: do not apply during rain or snow or at high humidity (>70%).
- Recommended ambient application temperature: +5°C to +35°C; application from -20°C to +35°C is permitted. The sealant temperature should be +20°C to +25°C. Ready to use.
- Do not dilute with water, as this may cause sagging, loss of adhesion and cracking.
- Apply and smooth the sealant with a putty knife.
- Protect surfaces with masking tape to ensure an accurate application and remove it immediately after smoothing the sealant.
- Apply a sealant layer 4.5 to 5 mm thick, with at least 3 mm of contact on both the opening and frame surfaces.
- Keep the packaging closed tight if there are breaks in work.
- Tools and surfaces should be washed with water before curing. Remove cured sealant mechanically.
*When using solvent-based paints, run a test.
