Sika Repair 13 F is a polymer-cement mortar developed on the basis of one component. The PCC product is used for structural or superficial concrete repair. It owes its properties not only to the presence of a polymer, but also to reinforcements made of synthetic fibers. It is perfect for filling cavities from 1 cm to 4 cm. Typically, these are defects related to exfoliation or damage to concrete in buildings or reinforced concrete structures. Sika concrete repair mortar complies with class R4.
The primary purpose of Sika Repair 13 F is to repair surface concrete and reinforced concrete structures. The mortar provides above-average resistance to weather conditions and humidity. This, in turn, makes Sika concrete repair mortar widely used in:
Sika Repair 13 F is ideal for repairing concrete exposed to harsh environmental conditions. By adding mortar to a concrete structure, it is possible to strengthen it and increase its load-bearing capacity and passivity. The preparation is also used to repair local defects. They are filled in layers.
The application of Sika Repair 13 F can be carried out by traditional techniques - by hand or by spraying. Before use, the mortar must be mixed with water in the proportion of 3 liters per 25 kg. The mixture should have a homogeneous consistency. Getting it usually requires at least 3 minutes of mixing with an electric stirrer. If you care about the stickiness of the mortar, you can slightly reduce the amount of water. The amount of consumption of Sika concrete repair mortar depends on the roughness of the substrate, the method of application and the losses associated with the application process.
Sika® Repair-13 F : water - 100 : 12 by weight 3 liters of water per 25 kg bag. To increase the stickiness and stability of the mortar (e.g. in a vertical, suspended or ceiling position), the amount of water can be reduced to approx. 2.75 liters per 1 25 kg bag.
Theoretical consumption: ~19.5 kg/m²/cm. Practical consumption depends on the roughness of the substrate, method of application, losses during application.
Minimum 1 cm / Maximum 4 cm in one laying cycle.
Waiting Time / Overcoating
The minimum technological break before applying any subsequent layers is (at +20°C):
