Technical features

After application the soluble silicates react with the carbon dioxide in the air originating colloidal silex hydrate which has remarkable fixative powers. The silex, reacts with the plaster’s calcium salts producing silicate calcium. The film free mineral nature offers optimum breathability & an excellent bond on lime plaster, cement mortar renders & civil plastering without flaking or detachment. SILREST FILL is not thermoplastic so a low-dirt pick up is guaranteed together with a mould and bacterial resistance thanks to its inorganic nature

A particular blend of inert fillers confer an optimum filling power which level rough surfaces without altering the hygrothermal balance. Said features in conjunction with the aesthetically appealing effects make an optimum product for the refurbishing of listed buildings & buildings of architectural interest
