MARMOFLEX HYBRID

Hybrid spreadable sealing membrane

MARMOFLEX hybrid is a hybrid water sealing membrane for flat roofs. After its application, it forms a single joint-free membrane that is impermeable even by stagnant water. The membrane offers complete sealing and breathability, excellent adhesion to old or new polyurethane or acrylic membranes and high resistance to weather changes (standing water, solar radiation, frost) and mechanical stress. Suitable for applications on flat roofs made of concrete, concrete slabs, mosaic or cement mortar, metal, wood, etc. Homogeneous, ready-to-use, industrial product of consistently high quality. It ensures good workability, increased application speed, it is economical and provides excellent results

Σύσταση & Χαρακτηριστικά

• Mixture of hybrid polyurethane/acrylic dispersions of high elasticity, enriched with special improving additives. • Complies with the specifications: ETAG 005 / EN 1504-2, concrete surface protection products/systems.

Εφαρμογή

• The substrate must be clean, dry and firm. • Wooden and metallic tips should be cut to a depth of approximately 3 cm and then covered with REFIXCEM fiber-reinforced repair mortar. REFIXCEM is also used for the healing of concrete nests. • At the points where the floor joins the wall, it is recommended to form a curvilinear tough approximately 10 cm wide with REFIXCEM. • Any cracks on the surface are filled with REFIXCEM. Then, after REFIXCEM has cured, a coat of MARMOFLEX HYBRID is applied locally and while it is still damp, a suitably cut piece of 5x5mm fiberglass mesh or polyester fabric is embedded. Finally, a second coat of MARMOFLEX HYBRID is applied to fully cover the reinforcement. • Before applying MARMOFLEX HYBRID, the surface must be primed with the special primer MARMOFLEX PRIMER. • The application of the first coat of MARMOFLEX HYBRID is done with a brush or a roller, after the primer has dried. The second coat is applied crosswise and after the first one has dried (usually 24 hours are required). The recommended thickness per coat is ~1 mm; • In areas of severe cracks and bonds or joints, in addition to the local use of 5×5 mm fiberglass mesh reinforcement or polyester fabric mentioned above, it is recommended to apply the reinforcement over the entire surface. The reinforcement is placed immediately after the application of the first coat of MARMOFLEX HYBRID, while it is still damp. • The overlap thickness of the reinforcement strips should be approximately 10 cm. The second coat should completely cover the reinforcement. • Application temperature between +5 oC and +35 oC.

Συσκευασία & Φύλαξη

• In containers of 13 kg, 4 kg • In sealed containers and in a dry environment, protected from frost and prolonged exposure to strong sunlight for 12 months from the date of production.

Κατανάλωση

Approximately 1.5 kg/m2 for a 1 mm thick coat, depending on the substrate.
