Sika MonoTop-4012 25kg – Fibre-Reinforced Concrete Repair Mortar

 It is a one-part, fibre-reinforced, low-shrinkage concrete repair mortar that turns damaged, weak or corroded reinforced concrete back into a strong, load-bearing surface — and all you add is clean water. Rated Class R4 (the highest structural class under EN 1504-3), it's the same professional-grade mortar engineers specify for bridges, dams and water tanks, now available over the counter at Shabbiri Hardware, Ongata Rongai & Tuala.

Why Contractors in Kenya Choose Sika MonoTop-4012

•  Serious strength: reaches roughly 56 MPa compressive strength in 28 days — stronger than most structural concrete.
•  Fibre-reinforced & low-shrinkage: resists cracking and stops the repair from lifting off the surface.
• One-part convenience: just add water — perfect for site crews and DIY structural repairs alike.
•  Built to last: sulphate-resistant and armoured against water, chloride and carbonation — ideal for marine, sewage and water-retaining structures.
• Deep repairs in fewer passes: build up to 120 mm thick in a single horizontal application.
•  Non-combustible: EuroClass A1 fire rating for total peace of mind.
•  Greener build: made with recycled materials and low embodied carbon.

How to Use It — 5 Simple Steps

1. Prepare: Break out all loose, weak or damaged concrete and clean exposed steel to bright metal.
2. Pre-wet: Soak the concrete with clean water for at least 2 hours so it's damp but not shiny (saturated surface dry).
3. Mix: Add the powder to 3.75–3.9 L of clean water and mix for 3 minutes to a smooth, lump-free mortar.
4. Apply: Work in a thin scratch coat, then build up wet-on-wet by hand or spray to the thickness you need.
5. Cure: Protect from sun and wind and keep the repair damp while it cures for maximum strength.
