Nails in Concrete Polishing

By Rick Amorey

My friend, under the impression that I'm a concrete polishing guru, invited me to his place a few weeks back to gauge his concrete floor. He wanted to know if it was fit for polishing. His nightmare for a floor turned out to be quite disastrous to my eyes. Thankfully, I was able to get my contractor to have a look. He said that, while dreadful, the floor still had a chance to be something special.

Last week, I got the chance to go back to my friend's place, upon the urging of the contractor. He seemed to really like what he had done, so I decided it was worth a look. What I saw was so worthwhile, it made me an even bigger fan of concrete polishing, if that was even possible.

When we were removing the carpeting that covered my friend's concrete, we realized that some genius decided to nail the carpet to the floor. The problem then became the chips and cracks left behind by this. My contractor had an idea, though. Perhaps he could use the crack lines as a guideline for a new design.

They decided to prepare the surface first using coarse grinding. Now, I have a limited understanding of how concrete polishing works, but I think I can explain. Basically, concrete polishing involves a batch of diamond tooling. The first few passages are meant for coarse grinding, and here they use low grits of diamonds. They do this to add design to the concrete.

Using the crack lines as a guide, he divided the floor into irregular, but artistic sections. Each section was then colored with a different dye, which he applied before going to the higher grits meant for the actual polishing. he said that this was necessary to lock the colors into the concrete.

As I've noted before, the end result was astonishing. Like mine, which sported a coffee-colored hue, my friend's home now has colored, polished concrete. His floor, however, was a combination of favorably-colored hues. Now my friend keeps on bragging at how better his floor is when compared to mine. Go figure. - 16459
