REPIFIX CLASSIC WRM 515

REPIFIX CLASSIC WRM 515 is a one-component, polymer modified, cement based repairing mortar for concrete. It is consists of cement, quartz sand, and additives. After mixing with water the resulting paste can be applied by trowel to repair the surface. REPIFIX CLASSIC WRM 515 does not shrink and has very good adhesion to concrete, frost and moisture resistance. It is suitable for inside and outside use. It is classified as a PCC R2 type repairing mortar for concrete according to EN 1504-3.

• Suitable for concrete or brickwork repair and patching, etc
• For groove formation on the connections between floors and walls (i.d. at the corners between the concrete slab and the basement floor, etc) or at the corners between the walls
• For leveling of irregularities or for parts of concrete surfaces that suffers from separation of aggregates
• It is produced in cotto color that is suitable for roof tile application (ridgepoles)
• After hardening, REPIFIX CLASSIC WRM 515 can be covered with waterproofing materials like bituminous base sealants or flexible cementitious waterproofing slurries.

• Non shrinkable with high adhesion strength to the concrete
• High mechanical strengths
• Application thickness up to 2 cm and up to 5 cm for localized repairs
• Resistance to humidity
• Resistance to abrasion

• Firstly, make sure that the surface is clean from loose particles and corroded or carbonated parts of concrete using a hammer or chisel or a sand blaster. In case of existing reinforcement, this needs to be exposed peripherally in order for the material to penetrate. Prior to the application roughen the concrete surfaces that will come in contact with the product. Remove all residues with water under pressure and remove any excess water. It is recommended to pre-coat the substrate and the metallic reinforcement with the primer WRM 510 before the application of the product, in order to ensure the optimum adhesion of the material to the substrate. The substrate must be slightly wet.
• In a clean container add 4,6-5 litres 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 5 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 CLASSIC WRM 515 repairing mortar taking care that there is a careful layering and covering of all voids.

Stored sealed in a dry environment with temperature above 0°C for 6 months from the production date.
