Award for the Calcedicampo basic plaster product at Klimahouse 2023 in Bolzano
Last Friday, on March 10, 2023, the company’s base coat product Calcedicampo was awarded a prize in the category of circular economy, protection of the environment and human health at Klimahouse 2023 at the Bolzano trade fair.

Calcedicampo base plaster is highly breathable, open to diffusion, very porous and hygroscopic, has thermal insulation properties, is mold-resistant and environmentally friendly. It is a product made from pure, recycled raw materials from the agricultural, food and brick industries. It is composed of pure, natural lime and granules from eggshells, amorphous ash from rice husks and cocciopesto – grit and flour in continuous grading and from bricks fired at low temperatures. The mortar is free of substances that are harmful to health and the environment. Calcedicampo base plaster is used to regulate and optimize the thermal and hygrometric situation in rooms. Condensation and mold form due to vapor-tight insulation materials on the outside, low diffusion capacity of the walls and/or thermal bridges. Thanks to its special composition and the resulting properties, Calcedicampo organic base plaster ensures a healthy indoor climate. It is ideal for sustainable, ecological, organic construction and renovation. Thanks to its excellent MBV value, Calcedicampo is a good substitute for clay plaster. This characteristic was tested and confirmed by measuring the Moisture Buffering Value Ideal (this parameter determines the amount of water vapor that is absorbed and released over a certain period of time in the event of fluctuations in relative humidity). The basecoat plaster also has high compressive strength and durability. The base coat is environmentally friendly, reduces CO2 emissions and reduces the consumption of raw materials. It is ideal for indoor and outdoor areas, on old and new masonry made of stone, brick, mixed masonry, concrete, aerated concrete, hemp bricks, rushes (reed mats), bamboo and straw. The plaster mortar has excellent compatibility with antique and historical materials and is therefore also recommended for the restoration of listed buildings. In the case of concrete and aerated concrete, the air, material and substrate temperature must be between +5°C and +35°C during application and the setting process. Concrete and aerated concrete must be primed in advance with Silifix – Calchèra San Giorgio to bind the water-soluble salts contained in these building materials and prevent these salts from blooming in the plaster. After a drying time of twelve hours, Fortis Vorspritz – Calchèra San Giorgio serves as a bonding bridge.
