Sika MonoTop-1010 25kg – Cementitious Bonding Primer & Reinforcement Corrosion Protection Coating for Concrete Repair

Sika MonoTop-1010 (25kg bag) is the professional's answer. It is a smart, one-part, cementitious, polymer-modified coating that does two critical jobs in a single product: it shields exposed steel reinforcement from corrosion, and it acts as a high-grip bonding primer that locks your new repair mortar to the old concrete. One bag, twice the protection.

Why Builders Choose Sika MonoTop-1010

• Two products in one — anti-corrosion primer for steel and bonding bridge for mortar.
• Stops rebar corrosion — actively protects reinforcement so repairs don't fail again.
• Rock-solid adhesion — bonds beautifully to both concrete and steel.
• Easy to use — single component, just add clean water and mix.
• Indoor & outdoor — perfect for columns, beams, slabs, tanks, culverts & bridges.
• Brush or spray — flexible application to suit your site. CE marked to EN 1504-7.
  

Where to Use It

Use Sika MonoTop-1010 as a reinforcement corrosion protection coating on cleaned, exposed rebar, and as a bonding primer beneath Sika MonoTop repair mortars. Ideal for structural and non-structural concrete repairs on columns, beams, floor slabs, balconies, staircases, water tanks and reservoirs, bridges, culverts and any concrete patch repair — inside or outside, above or below ground.

How to Use Sika MonoTop-1010 (Step by Step)

Step 1 — Prepare the surface
Break out all loose, damaged and carbonated concrete back to a sound base. Clean the exposed steel reinforcement to bright metal — remove every trace of rust, scale and dirt (wire-brushing or sand-blasting is best). Pre-wet the prepared concrete for at least 2 hours until it is saturated surface dry (SSD) — dark and matt, with no shiny water film.

Step 2 — Mix
Pour the clean water into a clean bucket first — about 5.25 litres per 25 kg bag for brush application (~5.0 litres for spray). Add the powder slowly while mixing. Use a low-speed paddle mixer (below 500 rpm) or mix by hand for at least 3 minutes until smooth and lump-free. Only mix what you can use within the pot life.

Step 3 — As reinforcement corrosion protection
Brush the mix onto the cleaned steel in two coats, each about 1 mm thick. Apply the second coat once the first is fingernail-hard. Cover every bar fully, including the backs where you can reach. Let it dry completely before applying repair mortar.

Step 4 — As a bonding primer
Work the slurry firmly into the pre-wetted concrete with a stiff brush, filling all pores and voids. Then apply your Sika MonoTop repair mortar wet-on-wet — onto the still-fresh, tacky primer — so both layers bond as one. Never let the bonding primer dry out before placing the mortar.

Step 5 — Cure & protect
Protect the fresh coating immediately from sun, wind, rain and contamination. Respect the pot life (~120 min brush / ~90 min spray at +20°C — hot weather shortens this). Wash all tools with water right away, before the material hardens.

Safety: This is an alkaline cement-based product. Wear gloves, eye protection and a dust mask when mixing. Avoid skin and eye contact, keep away from children, and follow the Sika Safety Data Sheet (SDS).
