Vandex Mineralit produces through a physio-chemical process an improvement in the surface structure of cementitious building materials. The crystallization resulting from the high silicic acid content produces compounds, which improve the strength and density of substrates.The substrate must be clean and free of any contamination and weak material. The substrate must be dry at the time of application. Apply Vandex Mineralit in one to two coats, by brush or low pressure spray.
To be applied by a suitably qualified contractor.
