Tips

• Surfaces to be sealed must be clean, dry and free from any dust, loose particles, oil and old sealant residues. Non-porous surfaces should be cleaned with solvent and a clean, non-fluffy cotton cloth. Excess solvent should be removed with a clean cloth.
• If needed, cover the adjacent surfaces with masking tape. For wide joints, use a backer rod to ensure the joints correct thickness and shape. Ensure sufficient ventilation at the working area.
• During the curing process, make sure that the sealed surfaces stay clean and are not under mechanical stress. 
• Due to the wide variety of construction materials, we recommend a preliminary compatibility test.
• Uncured product can be removed with PENOSIL Cleaning Wipes 941 or solvent. Cured product can be removed mechanically.
• Application temperature between +5°C and +40°C.
