Sika MonoTop-612 Repair Mortar, grey color, 25 kg bag | Sika

Technical Specifications & Usage

Sika MonoTop-612 comes in a 25 kg bag. It is a fiber-reinforced repair mortar designed for concrete substrates. The product features a gray color. It offers high resistance to abrasion and chemical attack.

Because of its fiber reinforcement, the material provides superior tensile strength. This allows it to bridge cracks up to 4mm without failing. You can apply it to vertical or overhead surfaces. The wet spray method ensures deep penetration into porous concrete. Manual application is also possible with standard trowels.

Performance in Saudi Climate

Saudi summers bring extreme heat, often exceeding 45°C. Standard repair mortars can crack under these thermal stresses. Sika MonoTop-612 handles this well. Its low heat of hydration prevents rapid temperature spikes during curing. This is crucial for Riyadh and Jeddah construction sites. The mix also resists the drying effects of sandstorms. Properly mixed, it achieves full strength in about 1 hour at 20°C. Adjust mixing time if working in hotter conditions.

Application Guide

Before applying, clean the substrate thoroughly. Remove loose dust and weak concrete layers. Dampen the surface slightly to prevent suction. Mix the powder with clean water to a creamy consistency. Apply the mortar immediately after mixing. Do not let the batch sit too long. For best results in 2026, ensure the ambient temperature is between 5°C and 35°C if possible.
