In general, concrete is recognized as a semi-permanent structural material because of its excellent durability and compressive strength.

However, concrete deterioration is promoted over time due to various physical, chemical and environmental factors, and if the surface of the concrete is left unprotected, aggregate exposure, surface peeling, cracking, rebar exposure and Various deterioration phenomena such as decrease in corrosion strength, penetration of chlorine ions, increase in porosity, carbonation, salt damage, leakage, etc. are caused, resulting in deterioration of the performance of the concrete structure, resulting in a serious problem in the actual structure. , The interior and exterior walls are waterproofed.

Conventional surface coating or waterproofing method has excellent mechanical, physical and chemical properties such as durability, acid resistance, alkali resistance, chemical resistance, elasticity, and waterproof/corrosion properties, and has excellent adhesion, and it is possible to construct a seamless continuous coating film, as well as to complex structures. A waterproofing method of coating a concrete structure with a polyurea resin coating film using ultra-fast hardening, which is excellent in applicability, is being implemented.

The waterproof construction of concrete structures using polyurea resin employs a so-called pure polyurea coating, hybrid polyurea coating, urethane rim polyurea coating, or the RIM spray coating method, which is generically referred to as such a coating method.

However, conventionally, additional components such as polymers or ground control agents were used, but various types of voids exist in the concrete structure, and the voids contain water contained in the process of mixing concrete, moisture absorbed by rainfall, snow, etc. Etc. are included, so even if the surface is dry and waterproofing, water vapor pressure is generated at the interface of the waterproof layer of the coating film due to the difference in humidity depending on the usage environment, or bubbles are expanded, causing pinholes and swelling to occur. The resulting problems remain.

In addition, when the concrete structure is not completely dried and is in a wet state, it is difficult to spray or paint the polyurea resin, and there is a problem that a pinhole phenomenon or swelling phenomenon due to moisture is also caused after construction.

Moreover, since the polyurea resin coating has to form a waterproof film by closely installing the outer surface or the floor surface of the concrete structure, there is a problem in that defects or cracks in the concrete structure occur or break.

This waterproofing work mainly uses a polyurea waterproofing method to construct roofs and exterior walls of buildings using polyurea resin as a waterproof coating material.

Polyurea uses a general construction method of manually spraying the paint supplied from the equipment using a two-component coating equipment. These methods have many problems when working with a manual gun, that is, spray (coating) film defects due to poor mixing of the main material (RES) and hardener (ISO).

Particularly, defects that occur frequently during construction may cause bubbles, uncured (not hardened), and the like. The polyurea coating film caused by such a defect phenomenon is not only very difficult to remove, but also has a disadvantage that it is difficult to repair.

Therefore, by using a spray (coating) painter, the wrong spray (coating) method by the operator that occurs during spraying (coating) is prevented in advance, and a good quality coating film is formed by maintaining a uniform spray (coating) coating film thickness. Devices that can do this are emerging.

Accordingly, the present invention has excellent waterproofing, curing, corrosion resistance, heat resistance, weather resistance, antifouling properties, etc., and particularly excellent in moisture permeability, so that bubbles, pinholes, or swelling can be completely prevented. Its purpose is to provide a waterproof material construction method in which a circular hollow particle type U-coat is mixed corresponding to a construction environment that prevents cracks and fractures due to improved tensile and elasticity.

Therefore, in the waterproof construction method that is constructed with a coating layer coated with polyurea that can block UV heat, develop various colors and apply to complex areas, and a thin film layer that blocks UV rays and enhances the durability of the polyurea coating layer on the surface of the coating layer. , The coating layer is biopolyol 10 to 60% by weight, chain extender 0.1 to 10% by weight, filler 10 to 70% by weight, antifoaming agent 0.1 to 1% by weight, plasticizer 0.1 to 10% by weight, pigment, UV stabilizer, anti-settling agent, Additive consisting of moisture absorbent and silane coupling agent 0.1-10% by weight of 4 kg of hardener mixed with 4 kg of curing agent and agitated dry primer installed on dry base surface with a moisture content of less than 10 ±2% and biopolyol 10-60 by weight %, chain extender 0.1~10% by weight, filler 10~70% by weight, defoaming agent 0.1~1% by weight, plasticizer 0.1~10% by weight, pigment, UV stabilizer, anti-settling agent, moisture absorber, additive consisting of silane coupling agent It is characterized in that it is composed of a wet primer that is applied to a moist base surface with a moisture content of 10 ±2% or more by mixing and stirring 3 kg of a hardener in 15 kg of a main substance mixed with 0.1 to 10% by weight.
