M&L for (i) Surface preparation: The concrete substrate must be sound and of sufficient compressive strength (minimum 20 N/mm2) with a minimum pull off strength of 1.5 N/mm2 for durable and lasting flooring. The substrate must be level, clean, dry and free of all contaminants such as dirt, oil, grease etc. All previous floor coating if any must be mechanically removed to the maximum extent possible. It is acceptable to relay on floor coating that has a firm bond (pull out strength of 1.5N/mm2). Concrete substrates must be prepared mechanically using abrasive blast cleaning, scarifying or grinding equipment to remove cement laitance and achieve an open textured surface. Weak concrete must be re moved and surface defects such as blowholes and voids must be fully exposed.Repairs to the substrate, filling of blowholes/voids and surface leveling must be carried out using appropriate repair product. The concrete or screed substrate has to be primed or leveled in order to achieve an even surface. High spots must be removed by grinding.
