weber accelerateur monocouche is a liquid setting accelerator solution for Monocouche through-coloured renders to speed up the time to scrape during colder application periods.


  • As a liquid component it can directly replace a proportion of the product gauging water
  • If added at the correct dose it will achieve 20 degree scrape times when working at 5 degrees.
  • Colourless liquid has no effect on the appearance of the finished product


weber accelerateur monocouche must be added to the gauging water for the Monocouche prior to adding the powder to ensure full dispersion. The correct dosage per 25 kg bag of Monocouche is 0.1 litres of weber accelerateur monocouche. Mix addition thoroughly into gauging water before adding powder. The total modified water mix must not exceed the allowable water content for the product used. When using a discontinuous mixer pump (such as a Putzmeister P11) the dosage per 6 bag mix is 0.6 litres of weber accelerateur monocouche replacing the same proportion of gauging water. When using a continuous mixer pump such as an M-tec Duomix every 10 litres of gauging water must include 0.2 litres of weber accelerateur monocouche.


The usage of the Monocouche product remains the same. Refer to the appropriate product instructions.
weber accelerateur monocouche solution will accelerate the initial set time such that, at 5 degrees working temperature, the scrape time of a Monocouche product will be the same as that during the summer months (20 degrees).
