bond Earth is a building material that bridges the traditional and the modern. Many cultures around the world have traditionally used and still use earth building materials, especially clay plaster. There are many good reasons: few building materials have such good environmental and mechanical properties and are also so abundantly available. In addition, the material’s ease of use as well as the ability to recycle it completely make it a good choice for users of all levels of experience. Fig. 1: Clay plaster, single coat Plasters are one of the most popular surface finish materials for walls both inside and outside. The composition of clay plasters and the ability to shape and work the material in many different ways make them an extremely versatile surface finishing material. Whether strongly textured or smoothed and polished, whether applied with a trowel or brushed-on like paint, conluto’s wide range of different clay plaster products can be used to achieve almost any surface

s, but can be used outdoors on surfaces not exposed to the weather. Clay plasters are not only used as finishing or decorative facing plasters but are increasingly replacing conventional choices such as lime, lime-cement or gypsum plasters. In bathrooms and kitchens, clay plasters can be used on all surface not directly exposed to splash water. For surfaces that are exposed to greater wear and tear, for example, corridors or staircases in heavy use, the suitability of a clay plaster, or the selection of a suitably durable clay plaster should be assessed on an individual basis. We can advise you on suitable options. www.conluto.de The properties of clay plasters Clay plasters do not set chemically but dry physically, hardening as the moisture in the material evaporates into the environment. By adding water, they can be made soft and malleable. This property means that mixed plaster mortar remains workable for long periods and that the material can be re-used without the need for ener

gy-intensive recycling processes. Clay plasters have good capillary conduction at a low level of equilibrium moisture. That means that it is effective at dissipating moisture and is therefore an ideal material for keeping the wooden structure of half-timbered buildings dry. Drying characteristics Moisture transport Clay plasters have the capacity to buffer fluctuating levels of humidity in rooms (for example from showering, cooking or heating): the material absorbs humidity in the air, retaining the moisture in its pores until the air in the room is drier, whereupon it is released again. This property is termed sorption capacity. Positive room climate conluto clay plasters are simple and easy to use. They are available in normal-sized packaging forms and can be prepared and applied by hand or using a plastering machine. Easy to use conluto clay plasters are electrostatically neutral and do not therefore attract dust and dirt. Electrostatically neutral The clay minerals within

the clay plaster are able to bind foreign substances and pollutants. Clay plasters are therefore widely held to “clean” the air. This cleansing property of earth is also used in naturopathy in healing earth and mud packs as well as in waste water treatment systems. Absorbs odours and binds pollutants Clay plaster requires comparatively little energy for its manufacture. The extraction and refinement of clay plasters do not destroy the face of the landscape nor pollute air or water. Conserves resources Because clay plasters do not set chemically, they do not suffer from the dehydration problems1 that affect conventional curing plasters, and it is not necessary to apply corresponding primers or barriers to prevent moisture loss. Wall surfaces should, however, be wetted with a fine spray of water to bind dust and prolong the workability of the plaster coat. Clay plasters are differentiated according to their composition, particle granularity, additives and mixing proportions. conl

uto clay plasters are made of naturally-occurring earths excavated from suitable earth pits along with sands of varying granularity. Different variants may be mixed with chopped straw or fine plant fibres. Are clay plasters subject to curing problems? 1 Composition of clay plasters 1: Curing problems occur with conventional plasters, mortars or paints when mixing water is absorbed too quickly by high-suction backgrounds. The water is absorbed from the plaster before it can adequately cure. This problem does not affect clay plasters. 4 | 5 Supply forms conluto clay plasters are available in a naturally-moist and/or dry state depending on the respective product. The package sizes, supply forms, and quantities are detailed at the end of this work sheet in the “conluto product finder” section and in conluto’s product overview brochure.

f closed plastering machines is that there is no danger of freezing in winter. Naturally-moist clay plaster Naturally-moist clay plaster is made directly from freshly-excavated pit earth and is not mechanically-dried. The energy input required to make these earth mixtures is therefore very low. Naturally-moist clay plasters are supplied in big bags. They should be used within three months of delivery on site. In the winter months, the material may freeze, however this has no effect on the quality of the product; it only leads to delays on site as the material must thaw fully before plastering can continue. Naturally-moist plasters can be processed using all open plastering machine systems (compulsory mixer plus mortar pump). Suitable machines include the PFT Wing N2V or PFT ZP3 with corresponding mixer, the Putzmeister S5 with corresponding mixer or the SP11 or P13, and the UMP1 L-Power by Deutsche Fördertechnik. These are just some common examples; other manufacturers also have suit

When stored dry, these products will last indefinitely. Dry clay plasters can be processed using closed plastering systems, for example the PFT G4 and G5 plastering machines or the UMP1 L-Power by Deutsche Fördertechnik. Mixing plasters conluto’s naturally-moist and dry clay plasters are both ready-mixed plaster mortars that only need mixing with water to be ready for use. The quantity of mixing water required varies depending on the kind of plaster and method of application. When applying plasters by hand, the mixture is usually prepared slightly thicker than when applied with a plastering machine. Likewise, the consistency of the plaster mortar should be adjusted depending on the thickness of the coat and the properties of the substrate.

It can be used as a bedding mortar for conluto insulation board systems or for single- or multicoat plasters on masonry, wood fibreboard, reed mats or gypsum dry-lining boards (primed with a coarse granular primer). The finely chopped straw gives the surface finish a fine texture. In most cases topcoat plaster is left as the final finish and painted. It can also serve as a base for a facing coat of deco clay facing plaster. Depending on when the surface is worked after plastering, the surface finish can be given a different texture. As a rule, the texture of the surface finish is finer the later the plaster mortar is rubbed or sponged. Smooth surfaces can be achieved by subsequently working the surface with a smoothing trow

lasters for creative interior wall finishes with a subtle, slightly cloudy appearance. Deco clay facing plasters can be applied to all flat and even substrates with a surface finish quality of Q2 or better. As deco clay facing plasters are made without additional pigments, their colours are a product of the specific earths and clays used. The result is a natural palette of colours that can be mixed with one another. Deco clay facing plasters must be applied at a universal thickness of between 1 and 2 mm. Uneven thicknesses lead to subsequent uneven working characteristics which in turn can result in an uneven surface finish. Cracking or spalling can also result. It is important that the substrate is very flat (surface finish quality level Q2) as deco clay facing plasters are unsuitable for filling holes or uneven substrates. conlino deco clay facing plaster is supplied in 25 kg sacks. 2: conlino is a range of creative clay plaster products by conluto and includes clay paints, brush-ap
