Tips

• Surfaces to be sealed must be clean and free from any dust, loose particles and oil 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.
• Due to the wide variety of construction materials, we recommend a preliminary compatibility test.
• Porous surfaces (e.g., porous concrete) should be primed to improve adhesion.
• Uncured product can be removed with PENOSIL Cleaning Wipes 941 or solvent. Cured product can be removed mechanically.
