Suitable backgrounds

Lightweight blocks, brick and stone. LC**** is not recommended for clay substrates. For loose or friable substrate, it may be necessary to consolidate with a hydraulic Limewash or a bonding agent.

Working Temperature

Not below 8°C or above 30°C. Ensure high suction substrates are thoroughly dampened before application. Avoid rapid drying due to high temperatures and strong winds by covering and curing with a light water mist as necessary.


Can be mixed in a cement mixer or using a whisk. Maintain slow revolutions (about 450-700 rpm) to prevent adding too much air that could change the properties of the mix. Mixing time must be at least 5 minutes until you obtain a uniform consistency with no lumps. Avoid manual mixing as it does not guarantee an optimum mix. Once the mix is ready is should be left to stand for approx. 5 minutes before use to allow proper development of the binder.
