Coverage

A 25 kg sack will give approx. 12 liters of mix. Grade 0–3 mm.


Application Conditions

The ambient temperature of air, mortar and substrate must be at least +5 °C. Do not apply the mortar in hot weather or when the site is exposed to direct sunlight.


Surface preparation

Remove any loose and damaged concrete. Pick-dress the edges of the area to be repaired to make them gently sloping. Remove concrete from around any exposed reinforcement steel (minimum 15 mm or 1.5 times the diameter of the reinforcement), clean it of rust to at least grade St2 and apply a protective coat of Finnseco-KOR anti-corrosion paint. MIXING THE MORTAR Add Finnseco-KL 30 powder to clean water (3.5–4.5 l of water to 25 kg of powder) 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:

REPAIRS Moisten the area to be repaired carefully 1–2 hours before starting. You can start the repairs when the moist area is no longer glossy. 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. Extensive areas several centimeters deep should be repaired in stages. In the first stage, pack mortar into the hole to a thickness of 20–30 mm. Let the patch dry for at least one day before continuing to fill it. If the damaged area is less than 15 mm deep and 100 × 100 mm large, fill it with Finnseco-KL 6 fine repair mortar. NOTE! When treating a surface containing asbestos, follow the Government Decision on Asbestos Work (1380/1994) and the related Decrees 318/2006 and 863/2010. Only mix the amount of mortar your can use in approx. 20 minutes. The repaired surface should be finished gently with a wood float.
