GECO ADDITIVE

LIQUID ADDITIVE FOR THE CREATION OF MACROPOROUS DEHUMIDIFYING MORTARS

GECO ADDITIVE is a liquid additive for macroporous dehumidifying mortars. Added to the mixing water of a normal cement, cement-lime or lime mortar, it creates a porous structure that increases the air flow in the plaster and speeds up the evaporation of the moisture contained in the wall.

It lets you make dehumidifying and renovating plasters on site with your usual sand and binders: the mortar becomes more breathable (μ 10.5, against μ 15/35 of traditional mortars at 1600-2000 kg/m³ (99.9-125 lb/ft³)) and more insulating. Non-toxic and non-corrosive, it is dosed simply: one 1 kg (2.2 lb) bottle per mix.

NOTE

Non-toxic and non-corrosive
For any mortar: cement, cement-lime, lime
