- PRODUCT PROPERTIES:
➢ MC-Nafuplan 404 FF bituminous membranes employ a compound consisting in distilled bitumen modified with Elastoplastomeric Polymers (APP). Its quality is highlighted by two indicators: flexibility at low temperatures (-5°C) and high temperature flow resistance (110°C). These parameters positively affect and contribute to increase the service life of the water proofing system.
➢ The good flow resistance at high temperatures of these membranes makes them ideally suited for application in warm climates and for use on thermally-insulated roofs.
- AREAS OF APPLICATION:
➢ Roof slabs.
➢ Terrace.
➢ Patios.
➢ Parapets.
➢ Concrete foundation.
➢ Basements.
➢ Pile heads.
- APPLICATION NOTES:
➢ Substrate preparation:
– Use the appropriate preparation equipment to achieve the required substrate quality. The supporting structure must be of sufficient structural strength to apply all new and existing layers of the waterproofing build-up. When used as a roofing membrane, the complete roof system must be designed and secured against wind uplift loadings.
– The substrate must be uniform, firm, smooth and free of any sharp protrusion or burrs, clean, dry, free of grease, oil, dust, and loosely adhering particles.
➢ Surface finishing: The upper surface is finished in film. The lower surface has a polyethylene film which melts when torched.
➢ Application: Application procedure may vary slightly depending upon site condition. However below given are general guidelines.
➢ Alignment: Unroll and alight MC-Nafuplan 404 FF correctly before torching. Overlaps should be a minimum of 10cm. In case of two or more layers, the sheets must be arranged in staggered rows with overlaps of the upper sheets in the middle of the lower sheets. Longitudinal overlaps must be in the same parallel to the slope.
➢ Torching: After torching the membrane, roll forward and press firmly against the substrate to bond.
➢ Caution: Do not over torch. Over torching will expose the reinforcement in the membrane and cause damage.
