Concrete grinding recommendation

[sbacro]

Hi all - new poster here. Appreciate all the phenomenal information I've been reading over the past few days as I get set to epoxy my floor. It's a relatively old slab, but seems moisture free (we've had a lot here in the NE lately, so I'm trusting it would have shown up). There's enough old sealant, paint, rough marks that I'm looking to have a professional grind the top layer (it's ~750 sq ft). A couple questions:

1. anyone have specific contractor recommendations in the Fairfield County, Connecticut area?
2. if not, who generally should I get in touch with about this type of job (e.g. paving company)?
3. about how much do people charge for basic grinding with some touch up fill-in work?

I'm sure someone covered this at some point but I'm not terribly good at searching old boards.

Thanks for everyone's help!

PS - I'm leaning to Wolverine. AlphaGarage, will be in touch soon with specs.

An epoxy contractor may be the best preparation company because they have the equipment and they know what you need. Other than that use a company that does grinding. Google often produces good results from "concrete grinding fairfield connecticut". Another source of info might be your epoxy supplier.

No matter if there dosnt seem to be moisture present you should still do a moisture test on the surface. Can either be a calcium chloride test or simple 12 X 12 inch clear plastic duct taped to floor for 24 hours.

After grinding out floor you may want to consider using a densifier or a moisture vapor block application to reduce any moisture numbers and potential out-gassing of concrete after the cut.

Two part A/B solvent based epoxy usually works best, keep an eye on temp. A polyaspartic clear may be substituted for clear epoxy top coat depending upon how late in year you finish job

There should be a good reputable applicator in your area. Don't let anybody talk you out of the grind out in favor of an acid etch especially on older surface

Diamond grinding does not take that much off to remove all your divots or inconsistencies your concrete may have. When the floor is really rough and wavy, we opt for a self leveling urethane concrete system, more info on that system here: http://bit.ly/oeSk5h, which gets poured at 1/4 inch thick.

With that said, we do service your area and we typically charge $1500 to diamond grind and clean your slab. More info on our concrete prep process here: http://bit.ly/pnIWCo

This Thursday I'll be in Riverside and Greenwich on appointments, I can swing by and see your place that day as well. Let me know.
