Recommendations:
• Before application, remember to protect the surroundings of the site from accidental splashes during spraying or washing with a protective film. The surface of the assembly must be flat, without holes or waves.
• It is recommended to carry out a test beforehand on a small surface to better assess the start of washing.
• Use a sprayer fitted with a metal nozzle with an opening of 0.79 mm, pressure of 2/4 bars.
Application:
• Spray:
◦ Thoroughly homogenize the deactivator before application. After 30 minutes of pouring the concrete, spray the surface evenly and in a single step, keeping the nozzle between 20 and 40 cm from the support, the jet must make an angle of 45° with the support.
◦ In the event of rain within a period of less than 3 hours after its application, it is necessary to provide a new spraying of the product or to ensure the protection of the treated surface.
• Washing:
◦ Between 4 and 24 hours after application of the deactivator, wash with water under pressure of 100 to 150 bars maximum. For more efficiency when washing, pre-wet the surface by hosing it down, and leave it for a few minutes.
◦ In case of strong exposure to wind and sun, wash between 4 and 12 hours if the temperature is below 35°C, and wash between 4 and 8 hours if the temperature is above 35°C.
