How long does it take to grind??

[krouchchocolate]

I am currently in the process of grinding my 600 sq ft 3 door garage right now and I was wondering how long does it typically take? I have been at it for about 6 hours now, and I only have 1/4 of the garage done. How are you guys finishing this up in 6-10 hours? At this rate, it will take me 15+ hours to finish the garage if I work non-stop.

They first gave me a worn out diamabrush so I went to the store and picked out a newer looking one. Using a clark FM1700 grinder that I borrowed from my friend. However, the diameter of the clark is a little bit bigger than the diamabrush. Could this be affecting the process?

Are you guys holding the grinder in 1 spot until the concrete turns into a "whiter" color? BTW, this is a brand new house, so the bare concrete looks pretty clean already. It does not really have any oil residue or anything like that on it.

Here was the original pad

that's not a grinder you are using. check out An Edco Floor Grinder.

None of my Home Depots have one I can rent.

You'll likely have to go to an industrial rental place instead of a home depot.

Agree, we have made many postings here about the limitations of Diamabrush. They really aren't grinders. Most tool rental places can assist you. A real grinder is heavier and has much larger diamond tooling that should make short work of your project!

The Diamabrush Should still be okay to use correct?

Absolutely! We sell the Diamabrush as a convenience item, and they work fine for light surface prep and such. For heavy grinding or on vary high psi concrete a traditional grinder may be much faster.

Some slabs are in excess of 5000 psi at the surface due to excessive power troweling. These floors will take longer than a hand troweled floor to grind. Keep in mind the DB cuts between 12:00 and 3:00 only. Hold in one place until it penetrates and then slowly move to the right. You can add a little weight to the top to encourage a better bite.

Ultimately, these over troweled floors are easier to prepare with a real diamond tool grinder like an Edco unit.

We use both types, a real diamond grinder and a db for edges and tight spaces.
