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.
Features and Benefits
- 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°C scrape times when working at 5°C.
- Colourless liquid has no effect on the appearance of the finished product
weber accelerateur monocouche is not an antifreeze.
weber accelerateur monocouche is not suitable for warm weather work other than sample areas.
weber's Customer Services Department has a team of experienced advisors available to provide on-site advice both at the specification stage and during application.

Preparation & Application
The instructions regarding the application of Monocouche renders still apply with respect to cold weather working.
The substrate must not be frozen and material should not be applied if there is a risk of frost within 24 hours.
The minimum application temperature is 5°C for all Monocouche renders.
Replace correct proportion of Monocouche mixing water with the weber accelerateur monocouche solution. Dosages are given in the application section.
Mix product in accordance with standard product recommendations using the modified gauging water.
If using an electric continuous mixer pump the feed water connected to the render pump must be modified to the correct dosage using a water butt feed.
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°C working temperature, the scrape time of a Monocouche product will be the same as that during the summer months (20°C).
Please note that the temperature of the mix may be different than that of the ambient temperature due to the water supply/ powder temperature. Due to this fact the setting period is only an given as an indication.
