ZB Fine Clay Plaster-dry
without straw 1000 kg

ZB - Fine Clay PlasterZB - Fine Clay Plaster is 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 and a wide range of applications make ZB - Fine Clay Plaster a valuable building material.
compositionZB - Fine Clay Plaster consists of various natural clays and sands in equal parts. Organic additives are possible.
Field Of UseZB - Fine Clay Plaster can only be used indoors. ZB - Fine Clay Plaster can also be used in three layers with full-surface overlapping reinforcement in heated wall areas. ZB-Fine Clay Plaster is not suitable as a base plaster and in areas with soil contact. ZB-Fine Clay Plaster is not suitable as a substrate for tiles.
PropertiesZB-Fine 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 substrates (clinker) and drywall systems (Fermacell, gypsum plasterboard) are to be specially pre-treated (mineral primer).
compensationUnevenness must be levelled with clay plaster before the actual clay plaster application. The levelling plaster should be removed flush with the surface and roughened, during drying, with a notched trowel or similar.
Preparation of the plaster mixturesZB-Fine Clay Plasters is delivered dry and mixed in a clean mortar tub with the required amount of water.
Apply plasterSlurry surfaces with a medium-fat clay slurry, then apply the Fine Clay Plasters on the still moist sludge. ZB-Fine Clay Plasters is applied with the trowel or sprayed on. A plaster layer should be between 3 and 6 mm thick. For larger plaster thicknesses multi-layered work is needed. Before applying the next layer, make sure that the earlier clay plaster layer is dry and roughened.
Surface TreatmentFine Clay Plasters is pulled off adequate to lot and horizontally and then rubbed with a wooden board or felted with a sponge board . By soaking the surface can also be reworked later.
Subsequent paintLoose parts are swept off the dry clay plaster with a soft broom. Subsequently, an open-pored, low-stress hardening paint system is applied. Pre-wet the clay plaster walls should be avoided.
safety instructionsNot mandatory
storageZB-Fine Clay Plasters is delivered dry in big bags and standard bags. It must be stored weather-proof on the construction site. The mixture should be watered regularly, especially under summer conditions, in order not to dry out the surface.
