Preparation of mortar: Empty the package (25kg) into ca. 5.5-5.75 l of clean water. Stir the mixture with a low-evolution agitator, until a smooth mass is obtained. Wait fro 2 minutes and stir again. The use of at least 2 containers is recommended, as this considerably facilitates fast and even pouring and joining of the cast screed fields. The mortar can also be mixed and fed with a mixing and pumping unit, with a design guaranteeing precise mixing and feeding of water. Attention should be paid so that water is not added in excess, as this may worsen the strength and increase mortar shrinking.
Mortar casting: The mass should be cast in parallel belts. Mortar portions should be cast in such a manner that the already cast fields could be connected when they are still liquid, which guarantees a smooth surface. The mortar can also be evenly distributed with a steel trowel or trapezoidal floating rule, at a desired thickness. Surfaces cast in this manner should be de-aerated with a spiked roller. Mortar should be laid non-stop, until the entire surface is covered.
