Store properly in undamaged original, sealed packaging; in dry cool conditions between +5 °C and +25 °C.

SikaTop® Armatec®-110 EpoCem® 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.

The Product comes in pre-packed units with the correct mixing ratio.

Pot life depends on temperature

Note: Pot life will be shorter at higher temperatures. Pot life will be longer at lower temperatures.

If applying the Product as bonding primer, respect the maximum waiting time before wet on wet application of Sika repair mortars and normal-setting concrete:

As reinforcement protection primer between first and second coat:

As reinforcement protection primer between second coat and subsequent repair mortar application:

For a total layer thickness of 2 mm, in two layers of 1 mm thickness each:

AS BONDING PRIMER ON MINERAL SURFACES

1.5–2.0 kg powder per m² and mm layer thickness, depending on substrate conditions

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.

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 (saturated surface dry).

1. Shake parts A and B before opening.
2. Pour the liquid parts A and B into a clean mixing vessel.
3. Mix for 30 seconds with a low speed (< 250 rpm) electric drill mixer.
4. While mixing parts A and B, slowly add powder part C. Avoid entraining air.
5. IMPORTANT Do not add any water to the mix. Mix thoroughly for at least for 3 minutes until a uniform consistency is achieved.
6. Leave to stand for 5–10 minutes until the mixed coating material exhibits a brushable, weakly dripping consistency.

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 1 mm thick to cover the reinforcement bars.
2. When the first coat is fingernail-hard, apply a second coat 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 medium-hard brush or spray gun to apply the Product over the complete substrate surface. Press the Product well into the substrate to form a thin layer, filling surface pores or cavities.
3. Apply the subsequent layer of repair mortar wet on wet.

Protect the fresh mortar from rain while the material has not yet set.

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