One-Part, Class R4, Multi-Purpose, Cementitious Concrete Repair Mortar

Sika MonoTop-4200 Multi Use is a cementitious, one-part, Class R4, multi-consistency (controlled by water addition), hand applied, pourable or machine applied, structural, sulphate resistant concrete repair mortar with high initial and final strengths. Suitable for repairing all types of reinforced concrete buildings, civil engineering and marine structures in all orientations (i.e. horizontal, vertical and overhead). Layer thickness up to 80 mm (pourable up to 60 mm).

High early and final compressive strengths.
Sulphate resistant.
Good adhesion to concrete, mortar, stone and brick substrates.
Good abrasion resistance.
Very low shrinkage.
Good surface finishing.
Ready to mix with water.
Excellent workability.
Applied manually or mechanically (wet spray).
High pH passivates steel reinforcement.
Contains very low chlorides and is devoid of other corrosion promoting additives.
Can be used for all orientations, removing the need for multiple products.

Usage

Sika MonoTop-4200 Multi Use may only be used by experienced professionals.

Repair of spalling and damaged concrete in infrastructure and superstructure works. Restoration work (Principle 3, method 3.1, 3.2 and 3.3 of EN 1504-9).
