One company is really pushing diamond grinding the surface with finer and finer grits. They claim it will leave a high gloss finish that protects the floor and lasts for years. They claim a sealant after the grinding is not necessary.
Help? Is this too good to be true? What's the truth on diamond grinding and the results? Should I consider other methods that would give a better result? Thanks in advance for a response.
