Sika MonoTop®-122 F is a high-performance, one-component, fibre-reinforced cementitious repair mortar specially designed for the repair, reprofiling and restoration of concrete and reinforced-concrete structures. It is formulated to provide excellent adhesion to properly prepared concrete substrates while delivering good mechanical performance, workability and durability.
The product is supplied as a ready-to-mix dry powder, which requires only the addition of clean water before application. Its fibre-reinforced formulation helps improve the overall integrity of the repair mortar and contributes to resistance against cracking and mechanical stresses.
Sika MonoTop®-122 F is particularly suitable for repairing damaged or deteriorated concrete in beams, columns, slabs, walls, balconies, structural elements and other concrete surfaces where localised repair and reprofiling are required.
Sika MonoTop®-122 F is based on a carefully selected combination of cementitious binders, graded aggregates, special additives and reinforcing fibres.
Cement, Selected Aggregates, Additives and Fibres
Grey Powder
After mixing with the recommended amount of water, the powder produces a cohesive, workable repair mortar. The incorporated fibres help reinforce the cementitious matrix and improve the stability of the applied repair material.
The formulation is designed to provide strong adhesion to suitably prepared concrete while allowing the mortar to be applied for repair and reprofiling work.
Sika MonoTop®-122 F offers several important properties for professional concrete repair:
These properties make Sika MonoTop®-122 F a practical material for restoring the profile, appearance and functionality of damaged concrete surfaces.
Sika MonoTop®-122 F works as a polymer-modified, fibre-reinforced cementitious repair mortar.
When mixed with water, the cementitious components hydrate and form a hardened matrix around the selected aggregates and fibres. The fibres help reinforce the mortar and improve its resistance to shrinkage-related cracking and mechanical stresses.
When applied to a properly prepared concrete substrate, the repair mortar develops adhesion with the existing concrete. This allows the material to restore damaged or missing sections of concrete and create a more uniform surface profile.
The effectiveness of the repair depends not only on the mortar itself but also on correct substrate preparation, mixing, application, curing and protection.
Sika MonoTop®-122 F is designed for repairing damaged concrete surfaces where material has been lost due to mechanical damage, deterioration or other causes.
It can be used for:
Damaged or deteriorated concrete around beams can be repaired and reprofiled using an appropriate cementitious repair system. Sika MonoTop®-122 F provides a practical solution for rebuilding damaged sections after proper preparation.
The product can be used for localised repairs to concrete columns where damaged or missing concrete needs to be restored.
Sika MonoTop®-122 F can be used for repairing damaged areas of concrete slabs and other horizontal structural surfaces, subject to suitable application conditions.
It is also suitable for localised repair and reprofiling of concrete walls and other vertical cementitious surfaces.
The incorporation of fibres helps improve the internal stability of the repair mortar and contributes to resistance against cracking.
The mortar is formulated to achieve good bonding with properly prepared concrete substrates.
As a one-component dry powder, the product requires only clean water for mixing. This simplifies transportation, storage and site application.
The mortar can be mixed and applied using standard construction equipment suitable for cementitious repair materials.
Its cementitious formulation and fibre reinforcement provide a durable repair system when properly applied and cured.
The material can be used to restore the original profile and shape of damaged concrete sections.
Because the product is supplied as a pre-blended dry powder, the contractor does not need to separately measure cement, aggregate and multiple additives on site.

Technical values such as density, compressive strength, flexural strength, bond strength, water demand and layer thickness should always be taken from the latest Sika Product Data Sheet for the specific Sika MonoTop®-122 F market version, because product specifications and packaging can vary by country.
Sika MonoTop®-122 F is mixed with clean water before application.
Only the recommended quantity of water should be used. Excessive water can adversely affect the strength, adhesion and dimensional stability of cementitious repair mortar.
Proper surface preparation is one of the most important requirements for achieving a durable concrete repair.
The concrete substrate should be:
Loose and damaged concrete should be removed until a sound substrate is exposed.
Where reinforcement is exposed, the steel should be carefully inspected and appropriately cleaned and protected according to the approved repair system.
Before application of cementitious repair mortar, the concrete substrate should normally be brought to an appropriate saturated surface dry condition without leaving standing water.
After surface preparation and mixing, Sika MonoTop®-122 F can be applied to the prepared concrete surface using suitable hand application or other approved methods depending on the repair area and project requirements.
The mortar should be firmly compacted against the substrate to minimise voids and ensure good contact.
For larger or deeper repairs, application should follow the manufacturer’s recommended layer thickness and system requirements.
Edges and corners should be properly formed to achieve the required finished profile.
Proper curing is essential for cementitious repair mortars.
After application, the repaired area should be protected from:
Appropriate curing methods should be selected according to site conditions and the manufacturer’s recommendations.
Good curing helps minimise drying shrinkage and supports the development of the designed mechanical properties.
Sika MonoTop®-122 F can be considered for a wide range of concrete repair applications, including:
Sika MonoTop®-122 F is a cementitious construction product and should be handled according to standard construction-site safety practices.
The product should be stored in its original, unopened and undamaged packaging in a cool, dry and protected environment.
Storage recommendations generally include:
The actual shelf life and storage temperature requirements should be confirmed from the latest local Sika Product Data Sheet printed on the supplied product.
Mixing and application tools should be cleaned with clean water immediately after use.
Once the cementitious repair mortar has hardened, it can generally only be removed mechanically.
Sika MonoTop®-122 F is a repair and reprofiling mortar, and successful performance depends on the complete repair system rather than the mortar alone.
Before repair, the cause of concrete deterioration should be identified. Possible causes may include corrosion of reinforcement, water ingress, carbonation, mechanical damage or inadequate previous repairs.
For structural concrete repairs, the structural condition should be assessed by an appropriately qualified engineer. Reinforcement corrosion and significant structural damage should not be addressed merely by applying surface repair mortar without proper assessment.
Sika MonoTop®-122 F combines the benefits of a pre-blended cementitious repair mortar with fibre reinforcement in a convenient one-component system.
Its excellent adhesion, good workability, fibre reinforcement and reprofiling capability make it suitable for professional concrete repair and restoration work.
The ready-to-mix formulation also helps maintain greater consistency compared with manually proportioning individual cement, sand and additives at the construction site.
Sika MonoTop®-122 F is a professional fibre-reinforced cementitious concrete repair and reprofiling mortar designed for restoring damaged and deteriorated concrete surfaces. Its one-component formulation, excellent adhesion, good workability and fibre reinforcement make it a practical solution for a wide range of concrete repair applications.
It is suitable for beams, columns, slabs, walls, balconies, concrete edges, localised repairs and other cementitious structures, subject to the specific project requirements and manufacturer’s recommendations.
By combining a pre-blended cementitious formulation with reinforcing fibres, Sika MonoTop®-122 F provides an efficient and durable approach to concrete restoration.
