Preparation & Application


The instructions regarding the application of Monocouche renders still apply with respect to substrate preparation and appropriate good practice.

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.

Fill a standard bucket with Monocouche powder (approx. 11 litres of powder). Measure out enough water to achieve a wet Monocouche mix (typically 3.5 to 4 litres of water) for weberpral M into an appropriate mixing trough in preparation for mixing the powder.


weber aretes chrono monocouche must be added to the wet mix of Monocouche to ensure the maximum working time is achieved. Do not blend neat weber aretes chrono monocouche with Monocouche powder.

It is recommended that the prepared powder and water components are mixed together mechanically with a drill and whisk to achieve a homogenous wet paste mixture.

Open a 2 kg sachet of weber aretes chrono monocouche and pour entire contents into the Monocouche and mix rapidly to achieve workable consistency. Do not add additional sachets of weber aretes chrono monocouche as working time will be seriously reduced.

Once mixed do not attempt to remix.


Apply product as required.

For the formation of traditional edges ensure that once the temporary formwork is removed (typically 1.5 hours) scrape the exposed edges to ensure a good future bond with the main application of Monocouche.

Do not apply outside the temperature range of +5°C to +35°C.

It is important that the main application of Monocouche follows the preparation of traditional edges in reasonable time to prevent contamination of the exposed faces.
