Harmony Deactivator is an aqueous surface deactivation agent, which poses no hazard to users and is harmless to the environment.

It can be used to delay the hydration of cement in an unshuttered concrete surface to a depth of 2mm for granulates of size 5 - 8 mm.

The final cleaning of concretes treated by this method will then allow the granulates to show through.

Prepare the support

To achieve good results, it is important that concrete should be of uniform consistency.

Thoroughly moisten the bottom of the mold to avoid cracks.

Always respect the dosage information.

For a homogeneous result, add Harmony Liquefying agent.

Carefully smooth the surface of the concrete without tipping too much.

The surface should always be flat, no holes and no waves.


After pouring and smoothing the concrete, wait for any bleed water to disappear

(approximately 30 minutes after pouring).

Before use, Harmony Deactivator should be homogenized by shaking.

Apply Harmony Deactivator in a uniform manner, using a spray system (nozzle with 0.79 mm opening, pressure of 2/4 bar).

Washing of concrete:

Concrete will be washed with water at a pressure of 100 bar.

The operator must take care to maintain a distance of 20 - 40 cm between the nozzle and the concrete surface.

The water jet must be applied at an angle of 45° to the concrete surface to be deactivated.

Time window for washing:

4 – 24 hours after application.

In conditions of severe exposure to wind and sunlight, washing should be completed between 4 and 12 hours if the temperature is lower than 35°C, and between 4 and 8 hours, if the temperature is higher than 35°C.
