Sika MonoTop®-1010 is a reinforcement corrosion protection primer in accordance with EN 1504-7 as part of the Sika® repair system. It is the first component of the system, followed by the application of Sika MonoTop® or SikaEmaco® concrete repair mortars.

Apply concrete repair mortar wet on wet onto bonding primer.

Apply concrete repair mortar wet on dry onto reinforcement corrosion protection.

Note: Consumption data is theoretical and does not allow for any additional material due to surface porosity, surface profile, variations in level, wastage or any other variations. Apply the Product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.

CONCRETE

1. Clean the substrate thoroughly so it is free from dust, loose material, surface contamination and material which reduces adhesion, prevents suction or wetting by the repair materials.
2. Remove delaminated, weak, damaged and deteriorated concrete, and where necessary, sound concrete. Remove using mechanical hand-held tools, high or ultra-high-pressure water blasting equipment.
3. Remove sufficient concrete from around corroded reinforcement to allow cleaning, application of a corrosion protection coating (where required) and compaction of the concrete repair mortar.
4. Prepare repair surface areas in simple square or rectangular layouts to avoid shrinkage stress concentrations and cracking while the repair material cures. This can also avoid structural stress concentrations from thermal movement and loading during the service life.

STEEL REINFORCEMENT

1. Remove rust, scale, mortar, concrete, dust and other loose and deleterious material which reduces bond or contributes to corrosion.
2. Prepare surfaces to bright steel, Sa 2 (ISO 8501-1), using abrasive blast cleaning or high-pressure water blasting equipment. Ensure the back of the rebar is also clean.

PRE-WETTING

Sufficient saturation of the concrete substrate prior to application enables the mortar to gain its full mechanical properties.

1. Thoroughly pre-wet the prepared concrete substrate for a minimum of 2 hours before application.
2. Keep the surface wet and do not allow to dry.
3. The final pre-wetted surface must achieve a dark matt appearance without standing water (saturated surface dry).

1. Pour the minimum specified quantity of clean water into the mixing vessel.
2. Gradually add the powder to the water while stirring slowly.
3. Mix for at least for 3 minutes until a uniform, lump-free consistency is achieved.
4. If necessary, add small amounts of water, within the allowed range, to adjust consistency. Do not exceed the maximum water content.
5. Check the consistency after every mix.

IMPORTANT

Strictly follow installation procedures

Strictly follow installation procedures as defined in Method Statements, application manuals and working instructions which must always be adjusted to the actual site conditions.

IMPORTANT

Risk of cracking due to application in direct sun or strong winds

1. Do not apply the Product in direct sun, strong winds or both.

REINFORCEMENT CORROSION PROTECTION

Preconditions

If using spray equipment, the substrate has been protected from overspray.

1. Use a clean brush or spraying equipment to apply a first coat of Sika MonoTop®-1010 1 mm thick to cover the reinforcement bars.
2. When the first coat is fingernail-hard, apply a second coat of Sika MonoTop®-1010 1 mm thick.
3. Wait until completely dry before applying repair mortar.

BONDING PRIMER

1. Remove excess water from within the surface pores and cavities with a clean sponge.
2. Use a brush, roller or spray equipment to apply a thin layer of Sika MonoTop®-1010 over the complete substrate surface to fill surface pores or cavities.
3. Apply the subsequent layer of repair mortar wet on wet.

Protect from wind, rain, frost and direct sunlight after application.

Clean all tools and application equipment with water immediately after use. Hardened material can only be removed mechanically.
