Abstract
The present invention is directed to a method of enhancing the appearance of a soiled porous surface. The inventive method includes applying a concentrated, alkaline, cleaning composition to the soiled porous surface. This concentrated, alkaline, cleaning composition is then allowed to remain on the surface for a period of time before it is rinsed with water. After drying, a maintainer composition is then applied to the surface. The maintainer composition includes a pore-filling component. The cleaning composition includes an alkaline source and, optionally, a solvent.
Claims20
A method of enhancing the appearance of a soiled concrete surface including pores comprising:
- applying a concentrated, alkaline, cleaning composition to the soiled concrete surface;
- allowing the cleaning composition to remain on the surface for a period of time;
- rinsing the surface with water;
- applying a maintainer composition to the surface, said maintainer composition including a pore-filling component, said pore filling component selected from the group consisting of plasticizers, oils and combinations thereof, said maintainer composition being diluted with water at a dilution ratio of 1:100 to 1:512 maintainer composition to water prior to applying said maintainer composition to the surface;
- allowing the maintainer composition to remain on the surface for a period of time;
- and
- removing that portion of the maintainer composition not filling in the pores from the surface.
A method of enhancing the appearance of a soiled concrete surface including pores comprising:
- applying a concentrated, alkaline, solvent containing, cleaning composition to the soiled concrete surface, said composition including about 0.1–50% of an alkaline source, 0.1–50% of an amine, and 0.1–90% of a solvent;
- wherein the amine is different from the alkaline source;
- allowing the cleaning composition to remain on the surface for a period of time;
- rinsing the surface with water;
- applying a maintainer composition to the surface, said maintainer composition including a pore-filling component, said pore filling component selected from the group consisting of plasticizers, oils and combinations thereof, said maintainer composition being diluted with water at a dilution ratio of 1:100 to 1:512 maintainer composition to water prior to applying said maintainer composition to the surface;
- allowing the maintainer composition to remain on the surface for a period of time;
- and
- removing that portion of the maintainer composition not filling in the pores from the surface.
