Hi Mereliv76,
Thank you for reviewing Behr Premium Solid Color Waterproofing Wood Stain. I'm very sorry to hear about the peeling issue experienced after snowfall, as it isn't typical or what we want our customers to go through.
The loose stain can be removed by power washing, sanding, or with a wood stain stripper. After stain removal, the deck can be cleaned with Behr All-in-One Wood Cleaner. The deck should dry for at least 24 hours before recoating within the recommended temperature (2-32C) and humidity (below 50%) range.
Customer satisfaction is very important to us, and I encourage you to contact Behr directly for further assistance. We'd love to learn more about your project and find the best way to help.
