Readymix plasters

Main component of plaster is sand resp. fine-grained gravel with a particle size up to 4 mm, depending on application. Furthermore binder and water are added to ensure stability after drying.

Mineral plaster contains binder like lime or lime hydrate, cement or portland cement, gypsum, clay or combinations of these materials. Mineral plasters are specially characterised by their regulating effect on ambient air humidity. After applying on brickwork the plaster builds up capillary structures during the drying process which are able to absorb humidity and desorb it short term.

Readymix plaster is available for various applications. Exterior plaster is differentiated into plaster which is applied on areas above the base of the building, on basement walls in the area of earth fill and on walls above the earth fill. Before use readymix plasters only have to be mixed with water. Readymix plaster protects facades and walls, adheres reliably, is mechanical resistant, forms no shrinkage cracks and is weatherproof and non-ageing as well as UV resistant.
Usually plaster is available in particle sizes of 2 mm, 3 mm and 4 mm and various colours, standard colour is white. Plaster is produced in a readymix plaster plant which consists of the following parts: screening machines, crusher and mills, weighing and dosing equipment, mixers, fluidised bed dryers with filter system, screw conveyors and conveyor belts, bucket elevators, shutes and silos. Furthermore the packing and loading unit are part of such a plant. In most cases besides the readymix plaster also tile adhesive and dry mortar are produced.

After drying and crushing of the mineral raw materials they are screened to the required particle size and mixed with various additives. The final product is packed in bags, filled in mobile silos or loaded as bulk material.
