How to level slightly uneven concrete floor

[Todd Brewer]

Three point tools occured to me but not always a good solution. I don;t want to add too much overall thickness if I can help it.

I need to find a local supplier of coatings. Not a Home Depot or Lowes. Otherwise I will live with what I have. It's not that bad, but if I could improve it without too much hassle I would.

How out is out? You haven't stated how unlevel it is, 1/8", 1/4" or larger. Is it high in the middle and lower to the sides, wavy, etc.

If its only off by 1/8" or so try some floor leveler and see what happens. If it cracks then you need to consider a wood floor. The wood floor will work fine with the floor leveler since it will spread the force across the floor and not just on 1 area where the machine is.

I have a 20x20 shop and my wood floor cost 700.00 or so and that was 3/4 OSB, pressure treated sleepers, insultation, plastic, screws and paint. I mainly did it for insulation but my back has felt better also.

It's not that bad, just enough that four legged stands/tables wobble. Not sure I want to put down a wood floor. However, I should give it some thought. I haven't built any cabinets yet so now is the time to do it. I'd have to have a slope or slight step down at doorways though.

I need an auto-leveling product that can tolerate 1/8" thickness or so. I would think epoxy based would hold up the best if it can tolerate the variation in thickness (paint-thin to 1/8" or so, maybe a hair thicker).
