MARMOCEM LAST

• The substrate must be clean and firm and must be wetted to saturation before application. • Wood and metal tips should be cut to a depth of approximately 3 cm and then covered with REFIXCEM fiber-reinforced, repairing 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 in the substrate are filled with REFIXCEM. Then, after REFIXCEM has hardened, a coat of MARMOCEM LAST is applied locally and while it is still damp, a suitably cut piece of reinforcement (fiberglass mesh/polyester geotextile) is embedded along the crack. Finally, a second coat of MARMOCEM LAST is applied to cover the reinforcement completely. • In areas of severe cracking and connections or joints, in addition to the local use of the reinforcement mentioned, it is recommended to use it universally over the entire surface. The reinforcement is placed immediately after the application of the first coat of MARMOCEM LAST, while it is still damp. The coating thickness of the reinforcement strips should be approximately 10 cm. The second coat that will follow should completely cover the reinforcement (a third coat may be required). • The contents of component A (25 kg mortar) is added gradually and with continuous stirring to a bucket containing component B (6.5 kg emulsion) using an electric mixer at low speed or a traditional mixer until a homogeneous mixture (paste), suitable for spreading, is obtained. • MARMOCEM LAST is applied in two coats crosswise, using a brush or a small brush, with the second coat applied when the first is slightly dry. MARMOCEM LAST is a spreadable, elastic, osmotic, 2-component sealant system. It reacts with the components of the cement and forms stable and insoluble salts which clog the pores and capillaries of the concrete by osmosis. It is suitable for the external and internal sealing of foundations, basements, conventional or inverted flat roofs, swimming pools, tanks, surfaces with capillary cracks and generally in any construction where sealing of the substrate is required. Thanks to the comprehensive, cohesive, elastic membrane that MARMOCEM LAST forms, it offers complete sealing and protection from moisture, excellent adhesion to the substrate, high resistance to negative pressures in bending and compression, as well as to temperature changes, while providing full breathability to the structural elements. If the first coat has already hardened, sufficient wetting must precede. • The thickness of each coat should not exceed 1 mm, in order to avoid possible cracking. • The freshly coated surface should be protected from rain, direct sunlight, dust, etc. • The application temperature should be between +5 oC and +35 oC. MARMOCEM LAST contains cement which is classified as an irritant. Consult the safety instructions and precautions listed in the Material Safety Data Sheet of the product.
