Description

Polymer-modified fiber-reinforced cement mortar containing additives that prevent shrinkage and improve thixotropy and adhesion. SILKO-approved (3.231).


Product Features

Straightening, filling and patching concrete structures, both on horizontal and vertical surfaces. Increasing structural thickness.


Recommended Uses

Mineral structures both indoors and outdoors requiring structural strength and excellent frost resistance such as bridge and port structures and parking buildings.


Coverage

Ready mix: A 25 kg sack will give approx. 12–13 liters of mix. Grade: 0–3 mm. Layer thickness: 5-20 mm, patching holes max. 50 mm.


Application Conditions

The temperature of air, repair mortar and substrate must be at least +5 °C. Avoid working when it is hot or in direct sunlight.


Surface preparation

Remove any loose and damaged concrete. The edges of the area to be repaired are pick dressed to make them gently sloping. Remove concrete from around the exposed reinforcement bars (minimum 15 mm or 1.5 times the diameter of the reinforcement), clean the reinforcement of rust to grade St2 and coat the reinforcement with Finnseco Tartuntalaasti. PREPARING THE MORTAR: Add the Finnseco-KL 50 powder to clean water and mix to an even consistency, e.g. with a whisk attached to a power drill or in a mixer. Let the mix stand for approx. 5 minutes and mix again before starting work.


Painting

First coat:

Repair: The area to be repaired is moistened carefully 1–2 hours before starting. You can start the repairs when the moist area is no longer glossy. Finnseco Tartuntalaasti is recommended to be used on smooth or unevenly absorbent surfaces. Pack mortar into the hole to be repaired with a trowel. This eliminates any air pockets that could weaken the bond. The mortar can also be applied by spraying with a paste-spraying gun. Several layers are used to repair extensive areas that are more than 50 mm deep. Let the patch dry for at least one day before continuing to fill it.
