ZB Universal Clay Plasters Earth-Moist
without straw 1000 kg

ZB Clay PlastersZB Clay Plasters are an ecologically optimized building material sourced regionally and with the possibility of individually mixed variants. Easy processing by hand or with machines, favourable building physics properties.
CompositionZB - Clay Plasters consist of different natural clays and sands in equal parts. Organic additives are possible.
Field Of UseZB - Clay Plasters can only be used indoors.
PropertiesZB - Clay Plasters can also be used in heated wall areas in three layers with full-surface overlapping reinforcement.
ZB - Clay Plasters are not suitable as a base plaster and in areas with soil contact.
ZB - Clay Plasters are not suitable as a substrate for tiles.
ZB - clay plasters are capable of vapor diffusion, body and air sound insulation, heat-storing, heat-regulating, moisture-regulating. They have a low equilibrium moisture content and are very easy to process.

Basic rules for the processorWhen mixing the clay plasters with gypsum, lime or cement-bound materials, the binding power of the clay is lost. Adjust the consistency of the plasters so that little mixing water is needed. Ensure adequate ventilation so that the masonry can dry out quickly. Clay plasters get their strength only by drying and do not bind by a chemical reaction with binders.
Processing UndergroundThe substrate must be firm, dry, stable and evenly absorbent. It must be salt-free and free from fungi (sponge). Less absorbent substrate (clinker) and drywall systems (Fermacell, gypsum plasterboard) are to be specially pre-treated.
CompensationUnevenness must be levelled with clay plaster before the actual clay plaster application. The levelling plaster should be flush with the surface and, during drying, roughened with a notched trowel or similar.
Preparation of the plaster mixturesFor example - clay plasters are delivered damp or dry and mixed in a clean mortar tub with the required amount of water.
Apply plasterSlurry surfaces with a medium-sized clay slurry, then put the clay plasters on the still moist slurry. ZB - Clay Plasters are raised or sprayed with the trowel. A plaster layer should be between 5 and 10 mm thick. Larger plaster thicknesses are achieved by multi-layered work. Before applying the next layer, make sure that the earlier clay plaster layer is dry and roughened.
Surface TreatmentImmediately after applying the clay plaster this lot?? and horizontally withdrawn and then rubbed with a wooden board or felted with a sponge board. By etching the surface can also be reworked later.
Subsequent PaintLoose parts are removed from the dry clay plaster with a soft broom. Subsequently, an open-pored, low-stress hardening paint system is applied. Pre-wetting the clay plaster walls should be avoided.
Nachträglicher FarbanstrichLose Teile werden von dem trockenen Lehmputz mit einem weichen Besen abgekehrt. Anschließend wird ein offenporiger, spannungsarm erhärtendes Anstrichsystem aufgebracht. Ein Vornässen der Lehmputzwände ist zu vermeiden.
Safety InstructionsNot mandatory
StorageZB - Clay Plaster will be delivered earth-moist in a big-bag. They are to be stored weather-protected on the construction site. The earth-moist mixture should be watered regularly, especially under summer conditions, in order not to dry out the surface.
