NOVELTY - Water-soluble epoxy paint composition for environmentally friendly concrete protection comprises 30-40 pts. wt. water-soluble phenol novolac epoxy resin, 1-10 pts. wt. modified graphene, 15-25 pts. wt. filler, 0.5-5.0 pts. wt. aminopropyltrimethoxysilane, 0.1-0.5 pts. wt. water-soluble dispersant, 0.2-1 pts. wt. complex antifoaming agent mixed with a mineral (mineral oil) and a silicone type, 0.1-0.5 pts. wt. wetting agent, 20-30 pts. wt. water-soluble amine curing agent, and 10-20 pts. wt. diluents. The complex antifoaming agent is a mineral-based and a silicon-based in the mass ratio of 1:1. USE - Used as a water-soluble epoxy paint composition for environmentally friendly concrete protection. ADVANTAGE - The composition: has high strength; increases the usage period of the structure; and reduces maintenance costs. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for concrete repair method using a water-soluble epoxy paint composition comprising chipping and removing latent, impurities, or deteriorated areas formed on the base surface using a grinder, a planer, a grinder, and/or a shot blaster, cleaning chipped area with a hand water jet or/and a vacuum aspirator, preventing penetration of water or chloride ions by filling the grooves or cracks formed on the cleaned surface with a waterproofing agent/repair agent, providing 0.2-1 pts. wt. complex antifoaming agent in which a mineral (mineral oil) and a silicone are mixed (in the mass ratio of 1:1), 0.1-0.5 pts. wt. wetting agent, and 20-30 pts. wt. water-soluble amine, forming a coating layer by applying a water-soluble epoxy paint composition curing agent on concrete surface.
