601 WETECH-REPAIR R4
Repair Mortar R4

AREAS OF UTILIZATION

• It is used as concrete repair mortar for the repair and restoration of concrete

prefabricated building elements on horizontal and vertical floors indoors and

outdoors, and for the repair and restoration of poured and broken surfaces on

walls and ceilings.

• It can also be used as a repair plaster to provide a smooth surface before tile application.

• It is used for repairing concrete after the formwork is removed, and also for filling

tie-rod holes and core cavities.

• It is used in the repair of surfaces that require very high strength (Highway, Bridge,

Runway).

ADVANTAGES OF THE PRODUCT

• It is fiber reinforced.

• It does not shrink.

• It reaches high compressive strength in a short duration after application.

• It can be easily applied at a thickness of 5-100 mm.

• It provides high adherence on concrete and plastered surfaces.

• It has high resistance to water and frost.

• It provides easy application.

• It provides the possibility of horizontal and vertical repair in concrete.

PREPARATION OF THE SURFACE

• Oil, dirt or materials that prevent adhesion should be cleaned from the surface,

materials such as mortar cement residues etc. should be scraped of and the

surface should be free of dust.
• If necessary, the application surface should be cleaned with water.

• In very hot and windy weather, the surface should be saturated with water.

• Before the application, WERIMIT WEPRIME-SATIN should be applied to the surface

in order to get a good result.

• Rust on the reinforcement to be repaired should be cleaned and dust free with the

help of a steel wire brush. The contact of the reinforcement bars with the concrete

should be cut off and at least 2 layers of WERIMIT WEPRIME-SATIN should be

applied with the help of a brush.

• The above data was obtained based on the results of laboratory tests, and values may

vary due to differences in the construction site environment.

APPLICATION

• 25 kg WERIMIT WETECH-REPAIR R4 (Repair Mortar R4) poured into 6-7 liters of clean

water. It is preferably mixed with a low-speed mixer so that no lumps remain.
• The prepared mortar is rested for 5-10 minutes to cure and used again after mixing for

1-2 minutes.
• WERIMIT WETECH-REPAIR R4 is filled by using steel trowel by applying pressure against

the broken, cracked, and broken areas on the floor.

• After its application, the surface is smoothed with a trowel. After the application, the

surface is finished with a damp sponge.

SHELF LIFE

• Shelf life is 12 months when stored in its unopened original package in a way that is not

exposed to moisture, dry and direct sunlight, provided that it is placed in a maximum of

8 rows on top of each other.
