Anti Corrosion Epoxy Coating SikaTop-110 EpoCem:   

SikaTop-110 EpoCem


Bonding agent and anti-corrosive coating




A cement-based epoxy-modified 3 component anti-corrosion coating and bonding





As an anti-corrosion coating for reinforcement steel:


For repairs to reinforcement concrete where there is corrosion of the underlying

reinforcement steel.

For the preventive protection of reinforcement steel in thin reinforced concrete



As a bonding agent for use on concrete, mortar or steel:


For repairs to concrete using SikaTop patching and repair mortars.

For bonding new concrete to old.




Excellent adhesion to steel and concrete.

Acts as an effective barrier against penetration of water and chlorides.

Contains corrosion inhibitors.

Provides an excellent bonding coat for subsequent application of repair mortars

(cement and epoxy based).

Not effected by moisture.

High degree of mechanical strength.

Pre-measured, ready-to-use packs.

May be sprayed applied.


Solvent free.


Storage and Shelf life


Stored in the original sealed packaging in dry conditions, this product will keep for at

least twelve (12) months.


Instructions for Use


Surface Preparation


Concrete, mortar, stone: the substrate must be clean and sound and free from all

traces of loose material, laitance, grease and oil.

Steel: surfaces must be clean and free from all traces of grease and oil, rust and mill





Shake components A and B vigorously before opening. Pour both liquids into a

suitable mixing vessel and mix for 30 seconds. Add component C slowly while

continuing to stir the mixture. Mix mechanically for 3 minutes using a slow-speed

electric stirrer (250 rpm) in order to entrain as little air as possible. Leave to stand for 5-10 minutes until the mixture exhibits a brushable, slow-dripping consistency.




When used as an anti-corrosion coating:


Apply a coating approximately 0.5-1.0mm thick to the cleaned and de-rusted

reinforcement steel, using a stiff paintbrush, roller or spray gun.

Leave to dry for 2-3 hours (at an ambient temperature of 20 C), then apply a

second coat of similar thickness.

Leave to dry for a similar period of time before applying patching mortar or repair.

In the course of application, some of the coating material will inevitably be

deposited on the surrounding concrete, but this has no detrimental effect on the

finished repair.


When using as a bonding agent for repair mortar or concrete:


Wet down the prepared substrate until the concrete is in saturated surface dry

condition then apply a bonding coat less then 0.5mm thick using a paintbrush,

roller or suitable spray gun. For best results, work the bonding slurry well into the

substrate to ensure complete coverage of all surface irregularities. Apply the

freshly mixed patching mortar or concrete, wet on wet, over the bonding slurry.


Maximum waiting times between application of slurry coat and application of

patching mortar or concrete:


+30C 15 minutes

+20C 20 minutes

+10C 30 minutes


Longer waiting times can increase risk of contamination of the bonding coat, which

can lead to reduced bond of following coats.




Use water to remove uncured material from tools and mixing equipment. Once

cured, SikaTop-110 EpoCem can only be removed mechanically.


Technical and Physical Data




When mixed: Grey slurry

A: White Liquid B: Yellowish liquid C: Light grey powder




Component A+B+C: 2.0 kg/litre (uncompacted density of slurry when mixed)

A: 1.25 kg/litre B: 1.03 kg/litre C: 1.10 kg/litre (dry bulk density)


Bond Strength


On concrete (sandblasted) 2-3 MPa approx.


Mix ratio


Part by weight:

1 part Component A:2.4 parts component B: 13.7 Component C


Potlife (8kg mix)


90-180 minutes (within the temperature range +5 C to +30 C)




Depending on the unevenness of the concrete substrate, not less than 1.2kg per m2

when used as a bonding agent. As an anti-corrosion coating, 3-4 kg per m2,

depending on the method of application (2 coats).




8 kg kit


Important Note


Minimum application temperature (ambient air and substrate) +5 C

Maximum substrate temperature +30 C

The recommended mix ratios should be strictly adhered to. On no account should

water be added to the mix.

Apply only to clean, sound substrates.


Handling Precautions


Avoid contact with eyes and skin.

Wear protective gloves and eye protection during work.

If skin contact occurs, wash skin thoroughly.

If in eyes, hold eyes open, flood with warm water and seek medical attention
