I'm always impressed with the smooth, level floors in a typical Home
Depot or Lowe's. They look like concrete with some kind of coating over
1. Anyone know what the actual construction of these floors is,
especially how they get the top layer so perfectly smooth?
2. What kind of contractors do this work?
3. Even though they may be an expensive overkill, are they practical for
home use, as an underlayment for ceramic tiles or Pergo-type flooring, ?
Yes, I am aware of self-leveling products that are hard to mix without a
1/2" drill, and even after mixing are thick enough to require troweling.
My situation is a bedroom where the edges of floor along three of the
four walls are about 1/4" below the level of the floor two feet in from
the walls. There are also some minor low spots in the center.
Polished concrete is usually called terrazo. Ask at the concrete place to
find out if any does terrazo in residential property where you live. Are you
sure that your house can support the weight? I'd get an engineer involved
since you may need somestructural reinforcemant.
You would need to give a lot more information. You never bothered
to tell whether your floor is a concrete slab or suspended on
The store's floors are concrete. The newest trend is to grind the
finished concrete after it is set with diamond. The concrete just
begins to shine at about 600 grit. If you really want to know
more about it, go here:
It is far too expensive to do under some other floor covering. If
you want to flatten a floor under flooring, the standard approach
would be to use a floor leveling compound. I prefer the cement
based/vinyl modified products. I prefer Mapei and Ardex products.
Keep the whole world singing . . . .
Can't imagine why you would want a super smooth, polished concrete
finish for a sub floor that Pergo, ceramic tile, or anything else is
going over. Pergo, ceramic, etc floors are installed successfully
every day over ordinary construction slabs, plywood sub flooring
And as others have pointed out, for existing construciton,
particularly if it's wood frame, you have the issue of supporting the
additional weight. There are methods to deal with leveling your
floor prior to applying most flooring products without going extreme.
Thanks everybody. The house is a ranch on a concrete slab. Now that I
have a better understanding of HD floors, I'll avoid that approach and
struggle with a self-leveling product and try to improve my poor
Same here. In fact I'd like to see a discussion in this group on
the merits vs. drawbacks of slab foundations. Probably not a
lot of love for them among repair guys, installers etc, but my
last house was the first one that had a slab foundation and I
loved it. Perfectly level floors, absolutely no creaks, squeaks
etc. It just felt a lot more solid compared to a pier foundation.
