Am I the only one who ruined a project with quick-dry poly on a humid day?
I was finishing a cherry wood table last week and picked a quick-dry polyurethane because I needed it done fast. The air was thick with moisture, but I ignored it and applied the coat. It looked perfect at first, drying smooth in minutes. But when I checked the next morning, the finish felt dry on top but was sticky underneath. I tried to sand it lightly, and my sandpaper got gummed up right away. Now I have to strip the whole thing back to bare wood, which is a huge pain. This happened to me before with a different brand, so it's not a one-off thing. Always check your shop's humidity or use a slower drying finish when it's muggy, or you'll waste hours fixing it.
