Caleosana : Insulating, macroporous, dehumidifying, anti-condensation plaster

Caleosana A plaster for interiors and exteriors that is macroporous, in respect of green building standards, with high thermal insulation and anti-condensation performance, having a base of natural hydraulic lime NHL 3.5, siliceous aggregates, metakaolin, granular expanded silica with an extremely high volume of interconnecting voids and a low elastic modulus. Its particular characteristics make it suitable for dehumidification, for heat and humidity treatments on buildings and walls, in ecological building operations and in the restoration of historical buildings and monuments. Caleosana does not contains traces of resins, solvents or radioemissive aggregates. Vintage and new construction masonries subject to rising damp, condensation, mildew. Recommended mainly for thermo-insulating anti-condensation rehabilitation of internal perimetral masonry and underground areas in general. Removal of degraded plaster up to the ceiling. Cleaning the resulting supports, including the removal of salt deposits; thorough dedusting and saturation with water, to obtain the condition "saturated with dry surface". In the presence of salt efflorescence brush thoroughly and spray the saline inhibitor Sanareg. If necessary, to increase plaster adhesion, apply a breathable anchoring scratch coat made with the specific lime-based preparation Untersana. Prepare the plaster by adding Caleosana to the mixing water, continue to mix until the desired mixture and the complete elimination of lumps is obtained. Apply with float and trowel or plastering pump. It is recommended to apply a minimum thickness of cm 2.5. Regularisation of the plastered surfaces with Sanastof lime-based ecological building fine mortar. Untersana rendering, applied by "spraying", must provide a rough, corrugated surface, designed to promote the bonding of the subsequent plaster, which must be applied no later than 2-3 days. For thicknesses greater than 2.5 cm, to improve the anti-cracking capacity, ensure the Armaglass 160 mesh is inserted. Protect fresh surfaces from direct exposure to the sun, the rain and the wind, cure the prolonged moist hardening. Approximately 9 kg/m² of Caleosana for every centimetre of thickness to be implemented (approximately 900 kg per cubic metre). Packaging: 25 kg bag Unit of Measure: €/kg
