FINOMIX® RP 4100
Fiber-reinforced high strength structural repairing mortar.
DESCRIPTION
Cementitious, one-component, controlled shrinkage, polymer-modified repairing mortar for demanding concrete
repairs.
Composed of high-performance grey Portland cement, silica sand, synthetic fibers, polymer resins and special
enhancing additives.
Suitable for layers up to 20mm thick.
APPLICATIONS
Suitable for repairing deteriorated concrete areas, both on horizontal and vertical surfaces.
It is suitable for:
 Restoring of deteriorated concrete which covers the reinforcing bars.
 Protection against reinforcement oxidation and corrosion on defective or worn concrete.
 Smoothing of flaws such as bird nests, construction joints, holes from mold bases, exceeding
reinforcing rods, etc.
 Filling of rigid joints
 Construction of surfaces which are subject to wear (ramps, commercial floors, etc.)
PROPERTIES



High compressive and flexural strength.
Modulus of elasticity similar to concrete.
Excellent adhesion to the substrate.
Great workability and thixotropy even at large width.
Fiber-reinforced for controlled shrinkage.
High water impermeability.
Very strong abrasion resistance.


Surfaces should be clean and free from dust, grease and other residual materials.
Remove all parts of the deteriorated concrete, until a solid substrate is revealed.
Old concrete surfaces and oxidized reinforcing iron should be thoroughly cleaned using a hammer or
chisel or a sand blaster to remove grease, rust, old paint and residual materials.
Apply two layers of FINOMIX RP 4020 anti-corrosion brushable on the exposed iron reinforcement.
Before applying the repairing layer, we recommend the coating of the surface with FINOMIX RP 4020
or FINOPLAST to creative a bonding layer between old and new concrete. Proceed with the application
of the repairing coat while the bonding layer is still damp.
Add the bag's content (25kg) into approx. 4.0kg of clean water under continuous stirring, until you
obtain a uniform lump-free mixture. We recommend the use of a low speed power drill (300 r.p.m).
Apply the mixture by pressing with a spatula or a trowel, at max. 20 mm thickness per layer.
When a second layer is required, the surface of the first layer should be roughened to achieve better
adhesion.
During the next few days protect the fresh mortar against harsh weather conditions (high temperatures,
strong wind, heavy rain, etc.) and make sure that is matures properly. The final surface should be

protected from premature dehydration by covering it with wet cloths or by spraying it every 3-4 hours
within the first 48 hours.
RECOMMENDATIONS





Do not mix the product with dirty or salty water.
During the application, temperature should be between +5ºC and +35ºC.
Do not add more cement, aggregates or other additives.
Do not add water once the mixture begins to set.
At high temperatures or strong winds, make sure to dampen the surfaces after application, in order to
prevent premature drying of the material which may compromise the properties of the product.

Note: Measures were carried out in laboratory environment conditions (Temperature: +22°C, R.H.: 60% with no ventilation). The
different conditions in the manufacture plant (temperature, humidity, ventilation, substrate absorption) may affect the properties of the
material.
SAFETY PRECAUTIONS
The product RP 4100 contains cement which reacts as alkaline with water and perspiration, and may cause
allergies and/or irritation.
Always wear appropriate personal protective equipment for eyes and skin (protective clothing, gloves and
goggles).
If skin contact occurs, rinse well with plenty of clean water.
In case of eye contact, get medical advice immediately.
CONSUMPTION
Approx. 16-17 kg/m2 for 1 cm thick layers.
