    APPLICATION AND INSTALLATION

    PREPARATION

    Concrete substrate must be at least 28 days old. Substrate must be sound, smooth, clean, dry and free from loose materials, oil, grease or any other contaminants. In case of substrate has moisture on surface use flame torch to dry up surface prior to apply primer.

    PRIMING

    Apply Maxshield Primer on prepared substrate at approximate coverage rate 5m2 per litre and allow to dry.

    APPLICATION

    Maxshield 400S should be install using gas torch. Slowly unrolled the membrane and flame torch the membrane until the bottom surface melt but do not over heat. Side overlap must be minimum 150mm. roll overlap joint must be minimum 100mm. Lap joint should be sealed by torch. All expansion joints, movement joints and all joints must be followed and allowed follow structural design. Other joints and end points must be allowed according to specifications. The membrane must be protected immediately after installation.

    Maxshield 400S must be installed by experiences, trained and approved applicators. Installation shall be strictly in accordance with manufacture method statement instruction.
