The surface must be clean, dry, and free from contaminants, that could have an adverse affect on the bonding of the membrane. Maximum humidity should not be higher than 8%. Fresh concrete structures must be left to dry for at least 28 days prior to applying the membrane.
Old membranes, dirt, grease, oils, organic substances and dust must be removed mechanically. Any possible surfaces irregularities must be rectified. Any loose parts on the surface must be removed.
Repair expansion joints and cracks, as necessary. In case of doubt, please consult our technical department.
