I'm sorry I don't know a lot about your issue, however it seems your flooring guy is willing to stand by his work. I would let him redo it, but I can't imagine that he can redo it the same way he did it before and get any different result.
Or just check with a moisture meter, and get a true reading. :thumbsup:painterman said:Could be moisture. Tape a 1 foot square piece of plastic to the bare areas if possible. Wait a couple of days and see if any moisture is trapped under the plastic.
The acid stain may not have been neutralized properly before sealer application.Thanks for the input.
Sorry I didn't make that more clear...yes it is the sealer that is peeling. The stain underneath seem to be fine.
Slab has a proper moister barrier under it so I cant imagine moisture being the problem.
I'm working on getting to the bottom of this. My floor man calls the product he originally put down an epoxy...it was an acid stain. He says he used the urethane sealer recommended by the company that manufactured the stain...I have no way of verifying that he did or didn't, he may have just used a clear poly thinking it would work as well. When I started researching this evening I noticed that that urethane he said he used requires a primer...I wonder if the primer wasn't used and that may be contributing to the problem.
He is working to fix the problem. This is a spec house so I have to be careful with the budget...but this isn't a hack contractor. He spends most of his time doing pool decks and porches in nicer neighborhoods, and does alot of commercial work. I hate to admit it but I've honestly never payed much attention...I always trusted him to know his stuff and honestly kind of felt like they're isn't much to wrong with stained concrete floors. Live and Learn I guess.
