Like concrete.  Good product

Easy to apply.  Expands quite a bit.  About triple.  Hardens rock hard, like concrete.

Good stuff.  It is easy to install, can be cut with a sharp, sturdy scissors or utility knife.  Plenty of edge pieces for straight sections.  This is not hard flooring, it is very soft foam floor.  We installed over concrete with just a think foam underlayment to act as a barrier. Heavier items placed on the floor will sink in a little and leave marks.  There is also some sort of coating, residue that will get on your feet and make other surfaces your walk on slippery.  Not sure if that will dissipate over time or not. Not really a complaint, just an fyi for others looking at this. We have been able to work out on the floor without worry of any pieces coming loose from one another. Very happy so far.

Good product and comes out good - not too mushy.

is a good product.  It is not thick or stiff like I thought. Maybe for some projects you would need that stiffness but not for what I needed it for.

Product seems to really adhere to concrete and it does flow readily.  Getting it to go and stay where you want it is a problem.  Some instructions and or suggestions would have been nice.  The volume is only 6 ounces and not 10 ounces.  The plunger on the caulk gun stops about 2/3 of the way into the tube...apparently because of the internal storage device of hardener and resin.

Very chic. I think it would be perfect if the base was more concrete looking than a painted grey. Still very happy with my purchase.

this product works very well, just like real cement but so simple to use.

I found the product to apply easy and virtually mess-less,  It was easy to apply and looked like a quality product.  My first coat is down and I ordered not slip additive to be sure my visitors don't slip in the rain.  Technical noted the non skid material is clear and won't show.  It turned my faded tinted concrete to a like new state.  Love it.

Bought these for working on concrete an hard or uneven surfaces they work great , the foam is thick an does not compress easily , the logo actually works to grip the surface , good product with a lot of thought to design put into them ,even came with a spare clip an storage bag.

Haven't had it long but It works well for finishing Concrete. Battery seems robust, hopefully it continues to hold its charge.
  In the month I've had it I would recommend

Pros:
One part is white, the other black, so just mix till it's gray, the color of concrete.
Has fine sand to mimic the texture and workability of concrete
Long, long working time (at least three hours) at 75F and in the sunshine
Great for large gaps (not small cracks)

Cons
Disposable, plastic putty knives recommended as this mix is very hard to clean up.  Sticks to everything.  Wear gloves.

Seems like a good product, the color is a little lighter than our other dark bronze fixtures, however, it blends in nicely, super flexible, hopefull will hold up well.

Good product.  A little larger than expected, but turned out good.

I had some concrete that had chipped away around a 4" basement floor drain. From the product description on the container, this seemed to be just the stuff to patch it with. The depth in the area to be filled was about 1/4". The area to be filled extended out about 4" around the floor drain. The repair area was dry, with the water level well below the floor slab.

I applied the DAP Pre-Mixed Concrete Patch with a drywall knife. After one week the stuff was still soft, I could push on it with my finger and see the indentation. I then began using a hair dryer to try and harden it. After about a month, and repeated hair dryer treatments, I decided it was hard enough to paint over, as opposed to ripping it out and starting over with something else.

Another reviewer mentioned that this is not concrete, but a vinyl polymer. I guess that makes sense, it did seem a lot like spackle to me. When it does finally cure, it is closer to silicone rubber than concrete.

Our kitty loves this.  There were no reviews when I bought it, but it seemed worth a try based on other options having negative reviews at twice the price.  To get it going, you have to get the water level just right, but then you can add a little water each day and it keeps on going.  We found out through trial and error that you have to have it on a level, solid surface, like a concrete or other hard floor, otherwise it won't keep running.

Item as described and works well with heavy doors on concrete and hardwood floors. I did not try on other surfaces but expect it will work well.
