- 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.
- Protect adjacent surfaces with masking tape for a neat finish.
- Apply a sealant layer 4.5 to 5 mm thick, with at least 3 mm of contact on both the opening and frame surfaces.
- Level the sealant with a putty knife or a brush before the surface film has formed.
- Remove the masking tape immediately after smoothing.
- After application, prevent the sealant from being in contact with water for at least 6 hours.
- Tools and surfaces should be washed with water immediately after use, cured sealant should be removed using mechanical methods.
*When using solvent-based paints, run a test.
