510 SURFACE HARDENER
A ready-to-use liquid for structural solidification, based on silicates, for use on concrete or cementitious surfaces.
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.
Consult Safeguard Europe Ltd technical literature for details. Safeguard Europe Ltd can also provide a design and specification service and it is recommended that they are consulted early in the design process.
Clean cured concrete to remove dirt, grease, oil and other surface contaminants.
Evenly to dry surfaces. After absorption, wash surface immediately with clean water.
