MAPE-ANTIQUE FC GROSSO By MAPEI
Smoothing compound
MAPE-ANTIQUE FC GROSSO is a salt-resistant, large-grained lime and Eco-Pozzolan cement-free, breathable skimming mortar for a rough finish on render.
WHERE TO USE
Large-grained skimming mortar for macro-porous, de-humidifying render for repairing old masonry deteriorated by the presence of capillary rising damp and soluble salts, including on buildings of historical and artistic interest. Large-grained skimming mortar for transpirant or “structural” base render. Large-grained skimming mortar for lime-based render deteriorated by the action of atmospheric agents and environmental conditions or by ageing.
Some application examples
- Rough finishing internal/external de-humidifying, macro-porous render when repairing masonry deteriorated by the presence of capillary rising damp and soluble salts.
- Rough finishing de-humidifying render on masonry in lagoon areas or close to the sea.
- Rough finishing new de-humidifying render or old lime-based render on stone, brick, tuff and mixed masonry, including on buildings of historical and artistic interest and listed buildings.
- Rough finishing transpirant or “structural” base render.
TECHNICAL CHARACTERISTICS
Mape-Antique FC Grosso is a pre-blended, large-grained, cement-free skimming mortar in powder form made from lime, Eco-Pozzolan, natural sand and special additives with very low emission level of volatile organic compounds (EMICODE EC1), according to a formulation developed in MAPEI’s research laboratories. This product is classified as GP according to EN 998-1 Standards: “General purpose mortar for internal/external render”, Category CS IV. When mixed with water in a suitable clean container, Mape-Antique FC Grosso forms a salt-resistant, largegrained, transpirant skimming mortar with a plastic consistency which is easy to apply with a flat metal trowel on both vertical surfaces and on ceilings. The properties of a mortar made from Mape-Antique FC Grosso, such as mechanical strength, modulus of elasticity and vapour permeability, are very similar to the ones of a skimming mortar made using lime, limepozzolan or hydraulic lime originally used in the construction of old buildings. Compared with these types of mortar, however, Mape-Antique FC Grosso also has properties which make the product resistant to various chemical-physical aggressive phenomena, such as the presence of soluble salts, freeze-thaw cycles, the leaching action of rainwater, alkali-aggregate reactions and the formation of cracks caused by plastic shrinkage. Typical values are shown in the Technical Data table (see Application Data and Final Performance sections) which refer to the main characteristics of Mape-Antique FC Grosso at both fresh and hardened states.
