1. A method comprising:
applying a first chemical to a surface; and
applying a second chemical to the surface after the first chemical is applied to the surface,
wherein the first chemical comprises a first percentage by volume of an organosilicon compound, a first percentage by volume of an alcohol, and a first percentage by volume of an acid,
wherein the second chemical consists of a second percentage by volume of the organosilicon compound, a second percentage by volume of the alcohol, and a second percentage by volume of the acid, and
wherein the first percentage by volume of the organosilicon compound is different than the second percentage by volume of the organosilicon compound, the first percentage by volume of the alcohol being different than the second percentage by volume of the alcohol, the first percentage by volume of the acid being different than the second percentage by volume of the acid,
wherein the first percentage by volume of the organosilicon compound is about 58% volume/volume and the second percentage by volume of the organosilicon compound is about 8% volume/volume,
wherein the first percentage by volume of the acid is about 0.11% volume/volume and the second percentage by volume of the acid is about 0.14% volume/volume,
wherein the organosilicon compound is dimethyldiethoxysilane, and
wherein the acid is sulfuric acid.
2. The method recited in claim 1 , wherein the alcohol is a secondary alcohol.
3. The method recited in claim 1 , wherein the alcohol is isopropanol.
4. The method recited in claim 1 , wherein the first percentage by volume of the alcohol is less than the second percentage by volume of the alcohol.
5. The method recited in claim 1 , wherein the second percentage by volume of the alcohol is more than two times greater than the second percentage by volume of the alcohol.
6. The method recited in claim 1 , wherein the first percentage by volume of the alcohol is about 53% volume/volume and the second percentage by volume of the alcohol is about 92% volume/volume.
7. The method recited in claim 1 , wherein the surface is dry when the first chemical is applied to the surface.
8. The method recited in claim 1 , further comprising drying the first chemical on the surface before applying the second chemical to the surface.
9. The method recited in claim 1 , further comprising cleaning the surface before applying the first chemical to the surface.
10. The method recited in claim 9 , wherein cleaning the surface comprises cleaning the surface with alcohol, rinsing the surface with water and letting the surface dry.
11. The method recited in claim 1 , wherein the chemicals are each applied to the surface using a wipette.
12. The method recited in claim 1 , wherein the surface is a granite surface.
13. The method recited in claim 1 , wherein the surface is a cement surface.
14. The method recited in claim 1 , wherein the surface is a plastic surface.
15. A method comprising:
applying a first chemical to a glass surface when the glass surface is dry;
drying the first chemical on the glass surface; and
applying a second chemical to the glass surface after the first chemical is dried on the glass surface,
wherein the first chemical comprises a first percentage by volume of dimethyldiethoxysilane, a first percentage by volume of isopropanol, and a first percentage by volume of sulfuric acid,
wherein the second chemical consists of a second percentage by volume of dimethyldiethoxysilane, a second percentage by volume of isopropanol, and a second percentage by volume of sulfuric acid,
wherein the first percentage by volume of dimethyldiethoxysilane compound is about 58% volume/volume and the second percentage by volume of dimethyldiethoxysilane compound is about 8% volume/volume, and
wherein the first percentage by volume of sulfuric acid is about 0.11% volume/volume and the second percentage by volume of sulfuric acid is about 0.14% volume/volume.
16. A method comprising:
applying a first chemical to a glass surface when the glass surface is dry;
drying the first chemical on the glass surface; and
applying a second chemical to the glass surface after the first chemical is dried on the glass surface,
wherein the first chemical comprises a first percentage by volume of dimethyldiethoxysilane, a first percentage by volume of isopropanol, and a first percentage by volume of sulfuric acid,
wherein the second chemical consists of a second percentage by volume of dimethyldiethoxysilane, a second percentage by volume of isopropanol, and a second percentage by volume of sulfuric acid,
wherein the first percentage by volume of dimethyldiethoxysilane is about 58% volume/volume and the second percentage by volume of dimethyldiethoxysilane is about 8% volume/volume,
wherein the first percentage by volume of isopropanol is about 53% volume/volume and the second percentage by volume of isopropanol is about 92% volume/volume, and
wherein the first percentage by volume of sulfuric acid is about 0.11% volume/volume and the second percentage by volume of sulfuric acid is about 0.14% volume/volume.
