REPIFIX RAPID WRM 518
Description
WRM 518 is a one-component, resinous, cement based, fast setting repairing material, type PCC R2 based on ΕΝ 1504-3.
Application Fields
- 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.
- After hardening, WRM 518 can be covered with waterproofing materials like bituminous base sealants or flexible cementitious waterproofing slurries.
Advantages
- Non shrinkable with high adhesion strength to the concrete.
- Fast setting product.
- High mechanical strengths.
- Application thickness up to 2 cm and up to 5 cm for localized repairs.
- Resistance to humidity and vapours.
- Resistance to ageing.
- Resistance to oils and solvents.
Application Steps
First ensure that the application surface is stable, clean and free of any dust, grease, loose particles, salts, oils and other contaminants.
Step 2Remove loose debris such as old peeled paints, old plasters etc.
Step 3In 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.
Step 4Leave 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.
Step 5Wherever necessary cast the part of concrete to be repaired and then pour the WRM 518 repairing mortar taking care that there is a careful layering and covering of all voids. 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. To obtain uniform strengths and to avoid crevices the final surface must remain 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 +50C and+350C and not under rain. When the temperature is high, the strength develops faster, while the workability of the material decreases.
Step 6In low temperatures, the strength development is delayed. The wooden casts must be well saturated but without forming water pools.
