Methods for polishing inorganic substrates
A composition for protecting a surface of an inorganic substrate, such as concrete, terrazzo, or ceramic tile, includes a silicate (i.e., an alkali metal polysilicate or a colloidal silica), a siliconate (e.g., a metal siliconate, such as an alkali metal methyl siliconate, etc.), acrylic latex, a silane coupling agent, and a solvent, such as ethylene glycol monobutyl ether. Inorganic substrates, such as concrete, stone, and ceramic materials, with such a composition on their surfaces are also disclosed, as are methods for polishing and protecting inorganic substrates.
1. A method for protecting an inorganic flooring surface, comprising:
applying a composition including a silicate and a siliconate to an inorganic flooring surface; and
with the composition on the inorganic flooring surface, burnishing the inorganic flooring surface.

4. The method of claim 1 , wherein applying the composition comprises applying a composition including a leveling agent to the inorganic flooring surface.
5. The method of claim 4 , wherein applying the composition including the leveling agent includes allowing gravity to enable the composition to spread substantially evenly across the inorganic flooring surface.
6. The method of claim 1 , wherein burnishing the inorganic flooring surface comprises polishing the inorganic flooring surface.
7. The method of claim 6 , wherein polishing the inorganic flooring surface comprises polishing the inorganic flooring surface to a glossiness that reflects at least about 80% of incident light when the incident light is directed toward the composition at an angle of 60° to the inorganic flooring surface.
8. The method of claim 1 , further comprising:
repeating the acts of applying and burnishing at least once.
9. The method of claim 1 , wherein applying the composition comprises applying a composition further including acrylic latex, a silane coupling agent, and a solvent to the inorganic flooring surface.

12. A method for protecting an inorganic substrate, comprising:
applying composition including a silicate, a siliconate, an acrylic latex, a silane coupling agent, and a solvent to a surface of an inorganic substrate; and
with the composition on the surface, polishing the surface to a glossiness that reflects at least about 80% of incident light when the incident light is directed toward the composition at an angle of 60° to the surface.
13. The method of claim 12 , further comprising: repeating the applying and the burnishing at least once.
