Rusting steel is the silent killer of concrete. Once water and air reach the reinforcement bars, corrosion begins to swell, crack and blow the concrete apart from the inside — and a small patch quickly becomes a big, expensive problem. 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.
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.
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.
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.
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.
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.
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.
