MULTIFIX REPAIR
Description
MULTIFiX REPAIR is a fiber-reinforced, thixotropic, cement-based, one component repairing mortar of high strength. It consists of cement, quartz sand, resins and special improving admixtures. Its special composition protects the reinforcement from corrosion and restores the passivity of concrete. It is non-shrinking and has excellent compatibility with old concrete, while it provides resistance to frost and moisture. After mixing with water, a homogeneous cementitious slurry of high workability is obtained, which can be applied with a trowel or steel spatula, even in greater thicknesses, directly on the surface to be repaired (internal/external). It is classified as a repairing mortar for concrete PCC R3, according to the standard EN 1504-3.
Application Fields
- Structural repairs and reinforcements.
- Restoration work on buildings and civil engineering projects.
- Protection of reinforcement against oxidation and corrosion in defected or deteriorated concrete.
- Repair of floors subjected to high loads (industrial floors, shopping centers etc.)
- Filling of cavities, in the edges of columns and beams, filling of cracks, groove formation, as well as creation or re-pair/filling of existing joints.
- Repair of stairways, parapets, prefabricated and other concrete elements.
- Repair of defects prior to the application of waterproofing.
Advantages
- Resistance to carbonation.
- Protection against chloride attack.
- Protection against water penetration.
- Shrinkage-compensation.
- Resistance to weathering – thermal cycles freeze-thaw
- Strong adhesion to the substrate.
- Greater thickness application.
- High mechanical strength.
- Excellent workability.
- Produced with quartz sand.
- Resistance to moister
- Resistance to abrasion.
Application Steps
In a clean container add 4,6-4,75 liters of clean water and gradually empty the content of the bag of MULTIFiX RE-PAIR (25 kg) while mixing continuously, in order to produce a homogenous mass of mortar.
Step 2Leave the mixture to cure for 5 min and mix again briefly. It is also recommended to periodically mix the mixture for as long as the repair last. The workable time of the product is 60 minutes. After the preparation of the mixture, the addi-tional addition of water to correct the workability of the mortar is prohibited. This shall lead to a decrease of re-sistances and to the increase of its shrinkage. The thickness of the mortar can reach 0,5 – 4 cm per application layer.
Step 3To obtain uniform strengths and to avoid cracks the final surface must be retained wet for the first 2 days following the application and rapid drying must be prevented by way of a suitable wet cover. Special care must be taken during the summer months, and for surfaces exposed to strong sun.
Step 4The product must be applied when the ambient tempera-ture is between 5°C and 35°C and not under rain. When the temperature is high, the strength develops faster, while the workability of the material decreases. At low temperatures, the strength development is delayed. The wooden casts must be well saturated but without forming water pools.
Storage
At sealed package for up to 12 months from the date of production, in areas protected from moisture, frost and sunlight.
