Applications: old concrete, terrazzo, Emery wear bare cement floor and all surfaces. Such as: warehouses, transport stations, factories, electronics factory, indoor parking, port facilities, shopping malls, stadiums, airports and so on. Product Description: permeability of concrete hardener is a performance improvement from the source technology. It is the main component of the inorganic silicates, he penetrate into the concrete of the concrete through the capillary, in particular under the action of a catalyst, the reaction activity of calcium in the concrete and metal ions other active materials, a crosslinked structure condensate glue, the more dense concrete surface, hardness, wear resistance becomes better improve the mechanical strength of the concrete. Effectively inhibit water, oil, and other corrosive substances immersed channels and compacting concrete, resulting in a clean, compact whole, greatly improving the surface hardness of the concrete strength, performance characteristics: green, easy maintenance, waterproof, anti- improve the performance of concrete dust, and extending the service life of concrete. Construction process: cleaning the ground: with washing machine or washing with water and brush construction, careful not to use acidic cleaners, use a neutral or alkaline cleaning agents for cleaning; polished floor: The No. 300-800 on the ground followed by grinding coarse grinding, trimming the ground is rough place, using No. 1000-3000 grinding, fine grinding in turn, so that the ground is smooth and light brightness. Spray sealer: use MF-B108 performed by low pressure sprayer or hand sprayer spray nozzle as close to the ground, a waste product to prevent atomized; within 30 minutes to keep the ground moist, dry surface within 30 minutes if you need to supplementary material, after 30 minutes if there is a concave plot material, with a dry rag. Polishing: After polishing spray on the ground is dry with 2000 r / min or more high-speed polishing machine; generally available washing machine fitted with 3M polishing pad, the first black, the red
