Coating composition with inorganic-elasticity and concrete waterproofing and water repellent method using thereof

摘要

The present invention relates to an elastic inorganic coating composition applied on a concrete base material, which comprises: 35 to 45 parts by weight of a first composition, 25 to 35 parts by weight of a second composition, 3 to 7 parts by weight of an inorganic elastic resin unit, 8 to 12 parts by weight of an inorganic elastic powder unit, 3 to 7 parts by weight of a water-soluble acrylic resin, and 8 to 12 parts by weight of cement or glass bead. The first composition includes silica, a powder resin, an antimicrobial agent, white cement, a hydrophobic additive, a thickening agent, cellulose fiber, and a curing accelerator. The second composition includes a silyl compound, an organosilane compound, amino siloxane, an aqueous acryl resin, a pH stabilizer, and a chelating agent. The content of the second composition relative to that of the first composition is 0.7 to 0.8. The elastic inorganic coating composition is applied to a concrete base material to provide waterproofing and water-repellent properties.
