Fine skim coat — UFIX SKIM COAT
UFIX SKIM COAT

Care should be taken to ensure that (USC) is thoroughly mixed. Small quantities (up to 10kg) can be mixed by hand using a suitable mixing drum or bucket. Greater quantities must be mixed with a mechanical forced mixer with a high shear stirrer. Use potable water while mixing and add water into the mixing vessel and with a mixer in operation, add one full bag of (USC) and mix for 3 to 5 minutes until a fully uniform and homogeneous mix is achieved. Dependent on the ambient temperature and the desired consistency the amount of water required may vary slightly but should not exceeded 10 liters. per 40kg of (USC). Excess mixing water may result surface crazing, cracking as well as lower strength and adhesion. Note: In all cases UFIX MONTRA must be added to water.

Setting begins after 30-45 minutes (at 250C substrate and ambient temperature) and ends after 75-90 minutes. The working period depends very much on the product temperature and on the amount of mixing water added. Therefore, the times given above should be regarded as a guideline. The lower the temperature, the longer the setting time. The less water added, the shorter the setting time. The addition of water to the mortar after it has started to stiffen is not recommended and the product should be discarded.
