DESCRIPTION
KKS® MORTATOP 382
is a one component, cementitious – modified polymer mortar that contains silica fumes and corrosion inhibitors and special additives.
ADVANTAGE
•    One component system requiring only the addition of clean water. 
•    No shrinkage, minimize surface cracking during hardening of the material.
•    Excellent bonding to steel and concrete
•    High mechanical strength
•    Alkaline passivation of reinforcement steel.
•    Spray-able using the wet spray methods
•    Anticorrosion, moisture insensitive and chloride resistance. 
•    Non-toxic and easy apply.
USE
KKS® MORTATOP 382 has the ability to protect reinforcement against corrosion in concrete. Used as a bonding layer to improve the adhesion of concrete repair mortar in the KKS® MORTATOP system, including:
KKS® MORTATOP 381 – High performance modified polymer repair mortar.
KKS® MORTATOP 382 – Bonding slurry and reinforcement corrosion protection.
KKS® MORTATOP 383 – High build modified polymer repair mortar.
KKS® MORTATOP FG – Cosmetic and repair mortar for concrete/mortar surfaces.
APPLICATION
SURFACE PREPARATION
For concrete
Concrete or mortar surface must be, clean and free of oil, grease and other maintenance coat preventing the adhesion. For large areas, use sandblasting or high pressure spray or chisel. For smaller areas, use needle gunning or jack-hammering will effective. Mortar and concrete surfaces must have a minimum compressive strength of 20MPa. 
For steel reinforcement
Steel reinforcement surfaces must be clean from rust, oil, grease or any other loosely adhering particles to provide a rust free surface.
MIXING
KKS® MORTATOP 382 must be mixed in a clean container with a low speed electric mixer (500 rpm). For small repairs, the KKS® MORTATOP 382 will be hand-mixed to ensure the subsequent repair mortar on the layer is still wet thus minimizing shrinkage. Pour enough fresh water into a small cleaned container, and mix until uniform consistency such as slurry. If the mixture becomes dense due to stagnant construction, it is recommended not to use it.
APPLICATION
Bonding agent purpose:
Apply by brush, roller or appropriate spray to wetted substrate. To achieve perfect adhesion, KKS® MORTATOP 382 must be covered onto the substrate surface, filled with uneven surfaces. Subsequent repair mortar should be applied on the connecting layer when it’s wet. 
Steel reinforcement protection purpose:
Use a slightly hardened brush, roller or spray device to apply the first coating about 1mm thick on the cleaned reinforced steel surface. Apply the second layer at identical thickness as soon as the first layer is hardened enough to receive following layer application (waiting time is min. 4 hours at 27 °C). Following repair mortars can be applied after a similar waiting time. 
CLEANNING OF TOOLS 
Remove non-hardened KKS® MORTATOP 382 products from tools and equipment with water. Hardened material can only be removed mechanically.
