SilibondLSI-726 stabilises weathered and worn building materials and protect it against acid rain. The modified silicate material penetrates deep into the structure where it supplements the missing binding agents and creates new stability. SiliBond Si-726 doesn´t create a film or a shell on the surface, the material is still breathable. The 1 component system, doesn´t change the appearance or the colour, it doesn´t contain water soluble side products which could lead to efflorescence. SiliBond SI-726 is suitable for the stabilisation of sucking stones, plasters and joint mortars and concrete. Do not use for sand stone and on weak sucking materials. The strengthening effect develops over 1 - 2 days time.
