How to use
- Apply the sealant to the surfaces cleaned from dirt, dust, cement residues, sealant residues or others. PU-foam sealant surfaces and concrete panels must be free of defects such as cracks, cavities and chips. Defects larger than 6 mm must be removed. For winter works, clean the surface of ice and frost. The sealant can be applied to both dry and moist surfaces. No drops of water allowed. The sealant should be applied no earlier than 24 hours after PU-foam sealant application. The surfaces close to the PU-foam sealant must be degreased. For degreasing, Silicone Remover KU-9100 is recommended. Caution! Do not use when it rains, snows or in high humidity (>70%).
- It’s recommended to apply the product at an ambient temperature from +5°C to +35°C, application at -20…35°C is acceptable. The temperature of the sealant should be +20°C… +25°C. The sealant is ready for use.
- Don’t dilute the sealant with water. Otherwise the sealant may flow off, lose adhesion and start 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.
- The sealant coating thickness should be 4.5 to 5 mm. The width of the sealant coating must be not less than 3 mm on each side of the opening and frame surfaces.
