This product is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed to ensure adhe

DESIGN CONSIDERATION In order to prevent thermal bridging or internal condensation ensure adequate provision of insulation (mineral wool or similar) within the joint prior to sealing. Always follow local construction and fire regulations. Design details need to be determined by the responsible engineer and building physicist. Application Limits SikaMembran® Universal is not resistant to mineral oils, petroleum, benzene, fuel and toluene etc. The bond line of the membrane must not be in permanent contact with water. METHOD OF APPLICATION Surface Preparation Prior the bonding process ensure that...
