REPIFIX RAPID WRM 518
Fast setting repairing mortar
REPIFIX RAPID WRM 518 is a one-component, fast setting, resinous, polymer modified, cement based repairing mortar for concrete.
Description
REPIFIX RAPID WRM 518 is a one-component, fast setting, resinous, polymer modified, cement based repairing mortar for concrete. It consists of cement, quartz sand, and additives. After mixing with water the resulting paste can be applied using a trowel to repair the surface. REPIFIX RAPID WRM 518 does not shrink and has excellent adhesion to concrete and remarkable resistance to frost and moisture. 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.
Application Fields
- Suitable for concrete or brickwork repair and patching, etc.
- Suitable 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.
- Suitable for leveling of irregularities or for parts of concrete surfaces that suffer from separation of aggregates.
Advantages
- Fast setting
- Non shrinkable with high adhesion strength to the concrete
- Rapid strength development
- Applied by trowel
- Resistance to humidity
- Resistance to abrasion
Implementation Steps
- 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 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 WRM 518 repairing mortar taking care that there is a careful layering and covering of all voids. Make sure that all the air cavities are removed and there are no voids. The thickness of the mortar can reach up to 1cm per layer.
- 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.
Storage
Store in sealed bags in a dry environment at temperatures above 0°C for 6 months from the production date.
