I used the Behr 1 part epoxy garage floor paint on a client's garage floor. Floor was sanded and cleaned thoroughly.
No traffic was allowed on floor for 96 hours. Floor looked fine and client was happy. Received a call from client several weeks later and was told that the paint was "coming up". I went next day and inspected, expecting intercoat peeling from clients description, even though I couldn't understand that with the prep work done initially.
After onsite inspection, the paint was not coming up or peeling, it was stuck tight. What it was doing was dissolving where water was dripping on it from the car's a/c drain. You could actually take your finger and work it up like water colors. Product also marked very easily from car tires and foot traffic.
Complained to HD store where purchased and was pretty much dismissed as being something I did. After heated exchange was told to contact Behr paint rep, which I did.
Asked the rep to come out and take a look at problem and was told that he didn't do house calls! I have been a paint contractor for 30 years and have had issues with products on occasion, but the one thing I will guarantee you is that if you have an issue with Benjamin Moore or Sherwin Williams, someone from the company will come and look at it and try to work with you.
