SikaTop-122 — Two-Component Polymer-Modified Repair Mortar for Concrete Restoration (30 kg)

Single-component repair mortars serve routine surface repair work adequately. But when the repair substrate is particularly smooth, contaminated with carbonation, or subject to movement and vibration — when the bond between the repair mortar and the existing concrete needs to be more reliable than a standard cementitious system can guarantee — a two-component polymer-modified mortar delivers the performance step-up that the application requires. The polymer component in a two-component system is precisely dosed, consistently mixed, and chemically integrated into the mortar matrix in a way that single-component polymer additions cannot replicate on site.

SikaTop-122 from Sika India Pvt. Ltd. is a two-component polymer-modified cementitious repair mortar engineered for structural and architectural concrete restoration where bond reliability, flexibility and durability are the governing requirements. The two-component system — a cementitious powder component and a liquid polymer component — are combined at the specified ratio to produce a repair mortar with consistent, controlled polymer content throughout the mix, delivering predictable bond strength, controlled shrinkage and a flexible cured matrix that accommodates minor structural movement without cracking or delaminating.

The repair mortar is suitable for trowel application on horizontal, vertical and overhead surfaces — restoring spalled and damaged concrete faces, rebuilding cover concrete over exposed reinforcement, repairing edges and corners, and surface restoration on structural and architectural concrete elements where the finished repair needs to perform both structurally and aesthetically. The two-component formulation also makes SikaTop-122 suitable as a scratch coat bonding layer before applying subsequent repair or finishing materials.

For structural repair contractors and civil engineers working on concrete rehabilitation where a two-component system is specified for its superior bond performance and consistent polymer content — SikaTop-122 delivers the repair mortar performance that reliable, durable concrete restoration demands.

A construction chemical repair solution from Sika for concrete restoration where two-component precision delivers what single-component convenience cannot — SikaTop-122 is the polymer-modified repair mortar specification for applications where bond performance is non-negotiable.
