A dry mineral mix based on clay, sand, and natural additives, designed to create decorative finishes with expressive texture and natural aesthetics. The product contains no harmful impurities, toxic substances, volatile organic compounds, or synthetic components — only purity in every particle.

Its coarse-grained texture allows for the creation of deep, lively surfaces with character — from subtle natural relief to more emotional, handcrafted effects.

This material is ideal for finishing interior walls and ceilings in spaces where tactility, naturalness, and a warm material presence are appreciated.

The plaster is applied to mineral substrates not exposed to direct moisture — such as lime, clay, or cement-based surfaces, as well as compatible existing coatings. It can be tinted with natural pigments, giving the space a unique appearance while preserving its natural harmony.

Regulates humidity and supports a healthy indoor microclimate
Compatible with clay, lime, and lime-sand substrates
Can be tinted with natural pigments

The substrate must be clean, solid, and free from dust, grease, mold, or remnants of old coatings. Surfaces with high or very low absorbency should be pretreated with a suitable mineral primer. It is recommended to use “Quartz Primer Grosso” for mineral or clay-based substrates. All irregularities should be leveled using appropriate fillers before applying the plaster.

Pour the contents of the bag into a clean container with water, using approximately 4.5–5.5 L per 12 kg of dry mix. Mix thoroughly with an electric mixer until a uniform consistency is achieved. Let the mixture rest for 10 minutes, then mix again. Use the prepared mixture within 8 hours. If necessary, slight adjustment of the consistency with water is allowed.

ARHE can be applied manually using a metal trowel or plastering hawk. Application in two layers is recommended, with a total thickness of up to 3 mm. The first layer should not be overly compacted or smoothed. After partial drying (2–4 hours), apply the second, finishing layer, which can be shaped according to the desired decorative effect.

Once the second layer is dry, the surface can be compacted or textured. For polishing, use a stainless steel Venetian trowel or a plastic float. A matte, grainy, or semi-gloss finish can be achieved depending on the tools used and the timing of the intervention. To enhance water-repellent properties, a special topcoat is recommended, such as natural wax.
