Mix the water at the following ratio: 1kg of powder to 100ml of water.

Due to the short working life of the mixed product, we recommend you carry out the mixing near to the repair and not near to the water source. Put the water into the empty bucket and gradually add the powder stirring constantly to achieve a pourable slurry.


When a smooth consistency is achieved, simply pour it in to the hole.

Working time

Approximately 5 to 10 minutes at 20°C, so do not mix at one time more than you can use within a few minutes.
