PROBLEM TO BE SOLVED: To provide a coating treatment method for the excellent waterproof and degradation prevention of a concrete floor slab and a waterproof and degradation preventive agent for the concrete floor slab. SOLUTION: In the coating treatment method for the concrete floor slab, the surface of the concrete floor slab is coated with an acrylic acid, a methacrylic acid and a polymerized resin composed of these mixtures or a composition cubically dispersing the resin in alcohol. The coating treatment method for the concrete floor slab is useful because it improves a waterproof effect and a degradation-preventive effect of the concrete floor slab. Special modified polyester and a composition containing the polyester have effects excellent in the shielding property of gas/liquid, and is effective as the waterproof and degradation preventive agent for the concrete floor slab.
