SikaCem 226 CI – High Strength Vertical and Overhead Repair Mortar (50 lb Bag)

SikaCem 226 CI is a high-performance, one-component cementitious repair mortar engineered for overhead and vertical applications in structural concrete restoration. This silica fume enhanced, fiber-reinforced mortar is shrinkage-compensated and contains an integral corrosion inhibitor to protect embedded steel. Designed for trowel or low-pressure wet spray application, SikaCem 226 CI offers excellent workability, high early strength, superior abrasion resistance, and strong adhesion to concrete substrates. Ideal for demanding infrastructure and industrial repair environments, this pre-packaged mortar simplifies installation and ensures long-lasting durability even in harsh exposure conditions.

Frequently Asked Questions:

Can SikaCem 226 CI be applied overhead?
Yes. It is specifically formulated for overhead and vertical repair applications, using either trowel or low-pressure spray equipment.

What is the minimum depth for application?
A minimum depth of 3/8" is required for both vertical and overhead installations.

Is a bonding agent required?
For optimal adhesion, use Sika Armatec 110 EpoCem as a bonding agent on concrete and rebar, or apply a wet scrub coat of SikaCem 226 CI just before mortar placement.
