Mixing and Handling
Caution must be used in exposed micro-silica applications, as concrete or mortar-containing micro-silica is darker than standard concrete. Micro-silica is very fine and dust may cause eye and respiratory irritation. Use good industrial hygiene practices (i.e. wear goggles and approved usage dust mask). For further handling and safety instructions, please consult the Material safety Data Sheet (MSDS).
