How does this hold up in northeast winters?

Thank you for your question. We apologize for the delay in response. Yes you can successfully use this product for your deck in your Ohio home. UV rays (sunlight) and moisture (rain/snow/dew) are wood’s natural enemies, so minimize exposure. Evaluate finish each spring and maintain as needed. Finish durability depends upon weather, wear and other local conditions, Sincerely, Alex @ Cabot Customer Support
