I live in ohio and just had a pressure treated pine deck built in April of this year. I have purchased the restore a deck system, and want to use TWP stains. Which do I use, 100 vs 1500? I would say that the deck receives full sun, as it sits south to southwest, in a newly constructed area with no mature landscaping.
For Ohio you need to use the 1500. Only 1 coat this year for new wood. You can always add a light coat next year if needed.
Thank you
