My garage had a concrete floor that was pitted so I had a professional epoxy the floor. I believe they said the put down 2 coats totaling 1/8th inch thick. Now that it’s done, I have water pooled in one area of the garage from snow melting off my car. One side of the garage is fine but about a third of the other side constantly has water pooled. I expected that the epoxy would self level and it would drain out the front. Should it drain like I expected it to? The people who did it said I have a low spot and that I’d need to buy a squeegee.
If your contract with the company that did the epoxy did not specifically address remediation of low spots or drainage issues, then you need to buy a squeegee.
Epoxy is not a leveling compound, and I know of no company that will advertise it as such. If you expected it to do so you were assumptive. I believe you got what you paid for.
