Abstract
A concrete treating composition including an aqueous solution of a polymer binder and water is disclosed. The composition is added to unset concrete during various concrete finishing steps in a process to treat the upper region of the concrete and protect the finished concrete from staining, wear, erosion, damage from chemicals and weathering. In an alternative embodiment, a wetting agent is also added to the composition.
Claims17
A method of treating concrete containing a wetting agent to protect the upper region of the concrete comprising the steps of:
- a) providing a binder which increases the flexibility and durability of said concrete, said binder being a copolymer which is capable of forming an aqueous dispersion when mixed with water, wherein said binder is a vinyl acetate/ethylene copolymer;
- b) mixing said binder with water to form an aqueous dispersion, said aqueous dispersion consisting essentially of said binder and water, in which the ratio of said binder is 5-20 wt % per weight of said aqueous dispersion;
- c) applying said aqueous dispersion of said binder and said water to a surface of said concrete before said concrete sets;
- d) penetrating said aqueous dispersion beneath said surface of said concrete to a desired depth;
- and
- e) allowing said aqueous dispersion to dry whereupon an integral, protective region of treated concrete is formed in said concrete.
A method of treating concrete to protect the upper region of the concrete comprising the steps of:
- a) providing a binder which increases the flexibility and durability of said concrete, said binder being a copolymer which is capable of forming an aqueous dispersion when mixed with water wherein said binder is a vinyl acetate/ethylene copolymer;
- b) providing a wetting agent which allows said aqueous dispersion to spread easily across said surface of said concrete by reducing surface tension of said aqueous dispersion, and which is capable of forming an aqueous dispersion when mixed with water, wherein said wetting agent is propylene glycol;
- c) mixing said binder and said wetting agent with water to form an aqueous dispersion, said aqueous dispersion consisting essentially of said binder, said wetting agent and water, in which the ratio of said binder is 5-20 wt. % per weight of said aqueous dispersion and in which the ratio of said wetting agent is 0.01 to 0.02 wt. % per weight of said aqueous dispersion;
- d) applying said aqueous dispersion of said binder and said water to a surface of said concrete before said concrete sets;
- e) penetrating said aqueous dispersion beneath said surface of said concrete to a desired depth;
- and
- f) allowing said aqueous dispersion to dry whereupon an integral, protective region of treated concrete is formed in said concrete.

- d) applying said aqueous dispersion of said binder and said water to a surface of said concrete before it sets;
- e) penetrating said aqueous dispersion beneath said surface of said concrete to a desired depth;
- and
- f) allowing said aqueous dispersion to dry whereupon an integral, protective region of treated concrete is formed in said concrete.
