PURPOSE: An aqueous acrylic one-component film waterproof agent composition capable of preventing the leakage of water generated by cracking of structures and the fracture of a film and having excellent physical properties such as adhesion to a substrate, weather resistance, durability and cold resistance and waterproof construction method employing the same are provided which are easy to use, reduce labor cost and are harmless and nontoxic. CONSTITUTION: The color film waterproof agent comprises 50 to 70% by weight of an acrylic emulsion, 1 to 5% by weight of water, 0.1 to 0.5% by weight of a dispersing agent, 0.5 to 1% by weight of a deforming agent, 5 to 10% by weight of a pigment, 15 to 35% by weight of an inorganic filler, 0.1 to 2% by weight of a dissolution aid, 0.01 to 0.5% by weight of a freeze stabilizing agent, 0.1 to 1.5% by weight of a thickening agent and 0.1 to 1.5% by weight of other additives. The waterproof construction method comprises the steps of executing slope work to enable water to flow easily on the concrete (10), forming an adhesion layer (11) by coating a primer on the surface of a substrate, forming a plurality of waterproof films (12) by coating a one-component film waterproof agent on the surface of the adhesion layer several times and forming a protective film (14) by coating a film protecting agent on the surface of the waterproof film. |
