REPIFIX RAPID+ WRM 520

REPIFIX RAPID+ WRM 520 is a resinous polymer-modified onecomponent, cement based, superfast setting (20min) repairing mortar for concrete. It is non shrinkable with optimum cohesion with concrete. After mixing with water the resulting paste can be applied using a trowel. It consists of special specification cement, quartz aggregates with high silicone dioxide content and of chosen granulometry, resins and special admixtures which improves workability, regulates hydration-shrinkage mechanisms and improves mechanical strength. It is classified as a PCC R3 type repairing mortar for concrete according to EN 1504-3.

• Suitable for restoration of damages on concrete deriving from constructional defects, wear, impact, etc.
• Suitable for repair and restoration of old and new, structural or non-structural concrete elements.
• Suitable for protection of the reinforcement oxidation and corrosion on defective or worn concrete
• Suitable for repairs of worn floors, cement screeds and other constructions based on cement
• Suitable for repairs of steps, parapets, pre-constructed and other concrete elements

• Sets in 20min
• Reaches its full strength in 24 hours.
• Excellent adhesion on the substrate
• Non shrinkable
• Superior strength
• Optimum workability
• It is produced with quartz sand.
• Resistance to humidity
• Resistance to abrasion
• Application thickness up to 5 cm locally

• Firstly, make sure that the surface is clean from loose particles and corroded or carbonated parts of concrete using a hammer, chisel or a sand blaster.
• In a clean container add 3,5-4 liters of clean water and gradually empty the content of the bag while mixing continuously, in order to produce a homogenous mass of mortar.
• Leave the mixture to mature for 3 min and mix again briefly. It is also recommended to periodically mix the mixture for as long as the repair lasts. Do not add additional water to correct the workability of the mortar. This shall lead to a decrease of resistances and to the increase of its shrinkage.
• Wherever necessary cast the part of concrete to be repaired and then place the REPIFIX RAPID+ WRM 520 repairing mortar taking care that there is a careful layering and covering of all porous or pits. Make sure that all the air pockets are removed and there are no voids. The thickness of the mortar can reach up to 5 cm for localized repairs.
• To obtain uniform strengths and to avoid cracks the final surface must be retained wet for the first few 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. The product must be applied when the ambient temperature is between +5 0C and+350C and not under rain. When the temperature is high, the strength develops faster, while the workability of the material decreases. In low temperatures, the strength development is delayed. The wooden casts must be well saturated but without forming water pools.

Store in sealed bags in a dry environment at temperatures above 0°C for 6 months from the production date.
