What specific tools to rent for Epoxy flooring

[iexaltu]

I have decided to do an epoxy floor coating for my garage which is about 450sf. This was supposed to be done before we moved into the house 4 years ago. However, the contractor put paint down the garage floor even though our contract said Epoxy. He ran out of money he said. Anyway, fast forward to today, I still want to do the project because the paint is peeling everywhere but would prefer to go the DIY route this time around. Since I have paint on the floor, I know I need to grind it. I've seen so much information on possible ways to accomplish this that I am a bit confused. Can anyone recommend exactly what to rent by make and model perhaps? Concrete grinding for dummies
What accessories and attachments would I need

I've heard that you can use

1)Floor polisher + Diamabrush grinder + Diamabrush prep tool?
2)Angle grinder?
3)10 inch grinder?
4)Planetary Grinder

If I rented these tools, would I require any accessories? I also looked at sunbelt rentals to see what is available to rent. I found the following list which is quite long https://www.sunbeltrentals.com/equi...surface-preparation-equipment/?items=915,917#


For those who have done this or do it regularly, what tools and accessories would you use for a garage my size? Would some of these tools/equipment combinations make things go faster? I found some recommendations for Edco but not sure which one to get and how fast things would be.

TIA

You'll need a 4.5" angle grinder with a diamond cup wheel and dust shroud. A walk-behind grinder, preferably a dual disc, and a compatible HEPA vac. I have no affiliation with SunBelt Tool Rental but have found that they typically can get you everything you'll need including a good selection of diamond tooling. Big Box HW store rental depts will usually have the single disc Edco at a minimum and many also have the dual disc available. The problem usually is that their HEPA vac selection is meager at best.

For a standard garage a 10 in grinder would suffice, but a planetary would make the job go faster. Make sure though that you don't rent a 230v machine and not have power available. We have seen customers grind floors with a 7" hand grinder but that's tough work. Most important is to make sure to rent the proper vacuum as most shop vacs will plug up in minutes. Use of a 'Dust Deputy' avaialable on Amazon does a great job of separating the dust prior to the vac.

Thanks for all the advice so far.

Based on all of the advice here, I plan on renting the following:

Is this the right vacuum? Do I need anything else for these? Some accessories maybe? How long can I expect to grind with a single disc edco vs. a dual disc for a 2 car 450sf garage? Am I better off using this tri-disc instead? https://www.sunbeltrentals.com/equipment/detail/915/0320065/diamond-grinder-electric-3-head/

Do I need to rent the magna-blades, dyma -dots and dyma-segs for the Edco or is one sufficient? I have attached some pictures of my garage for reference.

I would suggest a thorough degrease 1st using one of the readily available degreasers like Simple Green Industrial Cleaner, OilEater, Purple Power etc. and would avoid pressure washers.

Have SunBelt, or whomever you choose to rent from, set you up with a HEPA vacuum to match the grinder that you select. Wet/Dry vacuums will not work unless you use a debris separator like the Dust Deputy with them.

For 450sf a twin head Edco should be fine, I would count on a solid 4-5 hours of grinding though not including the edge work. The Lavinas are great machines and would probably knock that out in less than half the time but they are pricey and, at least with the SunBelt locations that I've dealt with, they do not rent the diamonds. You have to have or purchase your own which gets VERY expensive. Also, if you go this route, be absolutely sure that you have adequate and proper electrical supply or rent a propane unit.

SunBelt carries/rents a variety of Dyma-Sert tooling for the Edco's and will likely include a heavy duty extension cord as this protects the equipment.

I'd scape the loose paint, sand what's left and call it good.

Agree. Get a rotary floor sander like what is used for refinishing wood floors. Not the drum type. Go over the floor with coarse sandpaper, its cheaper than buying diamond pads. What doesnt come off with the sander is stuck real well. Apply the epoxy.
