So, I am talking about the concrete floor in my garage. The specific section is when when the garage door is shut, there is about 5 inches of this slab on the outside of the door. This 5 inches is not level and actually is angled towards the house. So, when it rains, water flows into the garage. My house is six years old.

I just recently got a contractor to put down a concrete overlay then stain and polish it on top of our basement slab. I am so utterly disappointed with the results. I want to now figure out what I can do to either fix it or cover it up. I'm also hoping to get opinions on whether or not I have the right to complain to the contractor and have him correct it. I've attached some images. There are a couple reasons I am so disappointed: [LIST=1] [*]The color has a sickly greenish hue to it, not the rustic amber we were going for [*]The amber color where it is applied is very patchy, ie: it looks like it was thrown randomly from a bucket in some areas and completely missed in others [*]The stain already is chipping and popping off (after less than a week) [*]The overlay is smooth and nice in many places and rough in others. It does not have the desired level of gloss (although I suspect it will look better in this regard if I put a wax or top coat on it) [/LIST] I was hoping for the kind of result you see if you google "stained concrete", ie: subtle and rustic looking and similar to a nice tile floor. I understand that staining of concrete is influenced heavily by the underlying material but this is on top of a white 3/8" overlay material that they put down. Surely being on top of an overlay would mean it could be better controlled and the underlying concrete would have no effect? What I know about the materials used is that they said they would use Butterfield Color Elements for the stain which I read is water based. They also applied a sealer, of what type I don't know but intend to ask just in case it is paintable. Likewise with the overlay material, not sure exactly what was used. Is this a bad contractor job or were my expectations too high? It looks to me like they didn't follow the manufacturers advice about applying the stain evenly with pressured air. It seems like they just slapped it on with something more crude. It is what it is now and I am hoping to get opinions on how to fix it. I'm thinking of these options: [LIST=1] [*]Get the contractor come back and redo the stain, my only worry being that I'll end up back where I am now or that my floor will be even patchier looking and/or more orange [*]Prep the surface somehow and put down a porch paint or epoxy and achieve a single tone (I would be happy with industrial garage gray at this point) [/LIST] Any advice for how to prep the surface? Could I just take the sealer off and apply one of the basement/porch paints on top of the overlay? Is there a more "breathable" option that would be less likely to bubble off in the event of moisture? Does anyone have experience sanding off concrete sealer? I would prefer to use this than a chemical stripper as we have an infant in the house and I can't easily clean the material out. Drum sander and several hours on the weekend would be enough to allow me to paint or epoxy? Thank you for reading this, any suggestions or shared experiences would be much appreciated. Evan
