Undulating concrete

Hello, first post here I believe, I like the wide variety of options for concrete topics. I will participate and learn, thank you all.

I'm posting in the polishing section because I believe one needs to get past my situation as rapid as possible to polish concrete.

Small areas of unflat concrete I use hand grinders, but for large areas and concrete that is flat 3/16" or less in 10 ft lengths but has undulations that need flattening for a luxury vinyl plank. I have read a post here on planetary verse counter rotating. Seemed like C R was better. I believe planetary is available for rental, a TPS machine may be harder to find.

I am willing to hand grind all/most of it, but looking for a standup machine that will remove drywall compound ,grind any non plane surface.

I do have quite a bit of experience in floor prep and have dust extraction vacuums, 10" grinder(rough grinding), planer,shot blaster etc.

Any recommendations on flattening a slab with surface imperfections extremely fast?

flar floors

Check out the Werkmaster brand of floor grinders. and they have lots of product videos on their website.They are not a planetary machine....they will level out a floor very fast, with the right tooling.

We normally float a floor

We normally float a floor after grinding to fill in the low spots. If it really bad we use a self leveling epoxy and flood the floor, come back next day and grind flat with a planetary. Or you can trowel down with a cement based product.

In any case, you have to charge for that labor and material.

any planetary will flatten

any planetary will flatten out your floor quick enough, as long as your diamond tooling is right. imo, . Dr j's suggestion on the workmaster will work fine also.

personally tho if your installing vinyl plank i would just lay some ardexK15 or some other SL down to get your nice flat floor you are looking for.  Good luck

Thanks, I assumed I would get

Thanks, I assumed I would get emails to notify of replys, nice to see a few choices. I am a little familiar with werkmaster, I don't know any local source for them. I will probably end up renting a planetary to decide for future purchase. Maybe a skanmaskin 450 if not larger.
