Hi JC,
Thank you for writing in. I'm sorry to hear about the peeling issue experienced with Porch & Patio Anti-Slip Floor Paint. It certainly isn't what we want our customers to go through.
To fix the peeling issue, I recommend sanding down the peeled areas to a smooth finish before cleaning and touching up. This coating requires a 72-hour dry time before going back to normal use and moving furniture back on the surface.
I understand this situation must be disappointing and encourage you to contact Behr's Customer Care Department for further assistance. We'd love to help.
Kindest regards,
Doris
